In recent years, development of hybrid solar cells which combines the advantages from inorganic materials and organic solar cells provides a simple, low temperature process to fabricate solar cell devices with reduced cost. Content of this thesis work was divided into two parts. In the first part, we demonstrated a PEDOT:PSS on GaAs thin film hybrid solar cells by using wafer bonding and chemical wet etching techniques. The thin film hybrid solar cells reached an excellent power conversion efficiency efficiency of 8.93% when an additional p+ Al0.3Ga0.7As epi-layer is deposited on the surface of the solar cells to provide a front-surface field. However, we uncovered that the bonding materials was able to diffuse into the GaAs thin film during the wafer-bonding stage, which led to the decrease in efficiency. In the second part of the thesis, we demonstrated an 4 inch PEDOT:PSS/silicon hybrid solar cell device by adding the DuPont Capstone FS-31 surfactant into the spin-coated PEDOT:PSS layer. Effects of the non-uniformity of the PEDOT:PSS layer on cell performance was investigated. The device achieved an overall conversion efficiency of 10.25% and a total output current and voltage of 26.23 mA/cm2 and 0.46 V, respectively. The as-made large-area solar cells benefits from the reduction in the fabrication time and cost, and particularly in preventing the pollution from the wafer-cutting.

Hybrid organic/ silicon solar cells employ low-temperature and solution processes and is compatible to be fabricated on bendable and thin substrates, making them promising candidates for future photovoltaic industry. However, scalability of hybrid solar cells has been limited by the uniformity of the organic thin film. In this work, we have developed a blade coating technique to expand the active area of the hybrid solar cells, from 1x1 cm2 up to 10x10 cm2 while minimizing the power loss upon scaling. First, an carbon-nanotube (CNT) doped poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) is employed as the hole conducting material for its high transparency and conductivity. The properties of CNT-doped PEDOT:PSS against the blade coating speed are tested, followed by the material modifications using surfactant and ethanol. By optimizing the amount of surfactant, we achieve a power conversion efficiency of 13.0% on a 1x1 cm2 device at the 200 nm/sec coating speed. Second, we scale up the cell area to 2x2 cm2 by optimizing the shadow ratio of the frontal silver grid, while controlling the uniformity of the film thickness at proper coating speed. An excellent PCE of 13.5% was achieved on the 2x2 cm2 device using 1wt% surfactant, 10% shadow ratio and 400 mm/s blade coating speed, showing an PCE enhancement factor of 13.4% compared to the spin coating process. Finally the film thickness and blade coating speed have been tested on a 6-inch silicon wafer for therealization of large-area hybrid solar cells. Preliminary results show that a cell with a 10x10cm2 active area exhibits a PCE of 6.9% possibly limited by the Ag grid design.

This thesis aims at the improvement of back-junction type PEDOT:PSS/Si hybrid solar cells, which was first proposed and demonstrated by Zieke and coworkers with a decent power conversion efficiency. The limited efficiency of current PEDOT:PSS/Si solar cells were basically due to the facts that the heterojunction was located on the front of the cell, resulting in a parasitic light absorption within the organic material. In addition, the rear surface of those front-junction solar cells was usually poorly passivated. To overcome above difficulties, one must place the PEDOT:PSS on the rear side of the device and the solar cell must be fabricated on a thin Si wafer to reduce carrier recombination. By adapting back contact cross-finger type PEDOT:PSS/Si heterostructures on thin Si wafers, we are able to reduce the shading loss to zero and enhance carrier collection. The absence of the metallization grid on the front side increases the short- circuit current (Jsc) of the cells dramatically. BackPEDOT cells with cross-finger type electrodes of different back emitter shading ratios were fabricated and tested. An optimized efficiency of 15.7% was achieved from cells with a shading ratio of 67%. It indicates that, at this particular shading ratio, diffusion lengths and carrier collection efficiency were optimized for both majority and minority carriers. By further increasing the width of Al electrodes from 200 um to 300 um and reducing the pitch between anode and cathode from 200 um to 150 um, the Fill Factor and efficiency of the BackPEDOT solar cells were further improved from 0.54 to 0.6 and from 15.7 % to 17.6%, respectively. Due to the cross-finger type electrodes employed on the devices, the rear side of the cells is not fully covered by the electrodes, which means that there are still exposed organic-silicon junction areas that can absorb sunlight. An efficiency of 1% was measured when the rear side of the solar cell was under 1.5AM illumination. Therefore, in principle, one can expect a total conversion efficiency of 18.6% when both sides of the cell are illuminated simultaneously.

Research work presented in this thesis is divided into two parts: (1) to investigate the interface of PEDOT:PSS/Si using X-ray photoelectron spectroscopy and simulations. (2) to enhance the efficiency of PEDOT:PSS/GaAs solar cells by using front-surface and back-surface field. (1)In this study, results from X-ray photoelectron spectroscopy indicate that the unsaturated carbons of PEDOT are bonded with the electron-withdrawing groups. The Gaussian simulations also show that the HOMO and LUMO levels of the PEDOT are mostly contributed from the unsaturated carbons. Therefore, chemical reactions are most likely to take place on those unsaturated carbons. Based on preliminary results from X-ray photoelectron spectroscopy, Gaussian simulations, and VASP calculations, we speculate that the unsaturated carbons on the PEDOT interact with oxygen or silicon atoms of the silicon oxide. (2)Planar hybrid solar cells based on bulk GaAs wafers with a background doping density of 1016 cm-3 and poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate), which demonstrated an excellent power conversion efficiency of 8.46%. The efficiency of the cell was enhanced to 9.87% with a back-surface field feature using a molecular beam epitaxially grown n-type GaAs epi-layer. The efficiency and fill factor reaches a record high 11.86% and 0.8 when an additional p+ GaAs epi-layer is deposited on the surface of the solar cells to provide a front-surface field. The demonstrated hybrid solar cells that combine GaAs and conjugated polymers at low temperatures provide a possible alternative technology to simplify fabrication processes and reduce costs.

Silicon is a high-performance material for solar cells. The hybrid solar cells combine the advantages of organic solar cells and inorganic solar cells. This study used PEDOT:PSS as the p-type organic semiconductor material and Si substrate as the n-type inorganic material to fabricate hybrid solar cells. Various device fabrication parameters were investigated systematically. We first discussed the influences of the native oxide forming time on the PEDOT:PSS coating. Then, we studied the influences of PEDOT:PSS coating spin rate and coating time on the device performance. The optimal device fabrication parameters were found to be a native oxide forming time of 4 hr and the PEDOT:PSS coating spin rate and time of 3000 rpm and 60 s, respectively. The Si/PEDOT:PSS solar cell based on the optimal fabrication parameters has exhibited a power conversion efficiency of 5.811%.

Current poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS)/n-Si solar cells have limited efficiency because the heterojunction was located on the front of the cells that resulting in a parasitic light absorption within the organic material layer. And the rear surface of those front-junction solar cells was usually poorly passivated. To improve aforementioned shortcomings, we fabricated back-junction PEDOT:PSS/n-Si with front-surface field and SiNx anti-reflection layer but no front surface textures, which demonstrated a power conversion efficiency of over 11 %. By incorporating either a random pyramid or a nanowire anti-reflection structure to the front of the cell surface to enhance light absorption, the power conversion efficiencies were further enhanced to 13.9 % and 14.5 %, respectively. Moreover, cells with nanowire anti-reflection structure showed omni-directional light-trapping characteristics over the random pyramid structure and were able to maintain the power conversion efficiency even at an incident angle as large as 60 degrees. On the other hand, we also fabricated back-junction PEDOT:PSS/n-Si with back contact cross-finger type electrodes. Thus the front side of the devices would eliminate the shading loss and enhance carrier collection. However, the photovoltaic parameters of the cells were not improved as expected. It was attributed to the lacking of lateral diffusion driving force for carrier collection at the cross-finger type electrodes.

In recent years, highly efficient organic/inorganic hybrid solar cells were developed due to their low-temperature fabrication and low-cost processes. However, loss in light absorption due to the surface reflection is still the major concern for solar cells. It is known that the similar refractive index between interface result in the lower reflectivity. The pyramid-shaped nanostructures fabricated on the surface are able to provide graded refractive index and, therefore, reduce the surface reflection and increase light absorption. In this report, we modified a Si substrate surface with pyramid nanostructures by combining the UV-curing nanoimprint lithography and chemical wet etching processes. The nanostructures improve anti-reflection effect and provide radial junction architecture that have enhanced light absorption and carrier collection efficiency. Compared with a planar device , the short circuit current density of the nanostructured device increase from 24.5 mA/cm2 to 34.8 mA/cm2.

Recently, with further intensified energy crisis and consciousness of environmental protection, solar energy has caught much attention due to its non-polluting and highly abundant properties. However, an efficiency-to-cost ratio of photovoltaic techniques is still too low to substitute for fossil energy. Therefore, developing a cost-effective or high-efficient solar device has aroused many interests and become a must in the field of energy harvesting. Here, a potential candidate that combines a silicon substrate with a polymer layer as a heterojunction solar cell will be elaborated. In this study, a Si nanostructure/poly(3,4-ethylenedioxythiophene): poly(stylenesulfonate) (PEDOT:PSS) heterojunction solar cell is proposed and examined. First, different lengths of Si nanowire (SiNW) structures formed by metal-assisted chemical etching (MaCE) were fabricated to discuss a trade-off between light absorption efficiency and amounts of e--h+ recombination centers at surface defects. A solar device with 200 nm SiNWs possesses relatively low reflectance and less trapping defects, resulting in the best performance among the designed lengths of the NWs. Nonetheless, PEDOT:PSS cannot fully infiltrate into 200-nm-length SiNWs. Moreover, without passivation of PEDOT:PSS, there appear lots of surface defects at the bottom region of SiNWs. Hence, a step of post-KOH dipping is executed after the MaCE process to widen the spacing among SiNWs. Several lengths of SiNWs were used as starting substrates and devices with 150-nm-long nanostructures owned the best performance for both the starting substrates with the 200- and 300-nm-long SiNWs that might stem from suppressed surface recombination and also reduced contact resistance, benefiting from a better coverage of PEDOT:PSS on the surface of SiNWs. Moreover, influences from PEDOT:PSS as a hole transport layer are also discussed. In principle, the mobility of PEDOT:PSS (~10-2 cm2V-1S-1 for pristine film) is much smaller than Si’s (~103 cm2V-1S-1); thus, there exists a recombination region at the interface between Si and PEDOT:PSS due to the unbalanced mobility between an electron and a hole. Hence, in order to escalate the mobility of PEDOT:PSS, secondary dopants such as dimethyl sulfoxide (DMSO) and graphene oxide (GO) were mixed into PEDOT:PSS and a solar device based on the modified PEDOT:PSS of 0.2 wt% GO addition provided the best mobility and thus the best efficiency. Such Si nanostructure/PEDOT:PSS heterojunction solar cell could be simply fabricated via low temperature wet etching and spin-coating methods that can dramatically reduce fabrication cost. After optimizing the Si nanostructures and the amount of the secondary dopants, power conversion efficiency above 13% can be achieved and is believed to be ready for applications of energy harvesting.
