Texto completoLes performances et la durée de vie des cellules solaires organiques sont fortement dépendantes de la qualité des matériaux de la couche active et des interfaces dans le dispositif. Dans ce manuscrit, nous avons développé des nouveaux matériaux hybrides organiques-inorganiques pour favoriser le contact entre les matériaux donneur/accepteur d’électrons et ainsi faciliter le transfert de charges à travers le dispositif. Tout d'abord, la synthèse de poly(3-hexylthiophène) P3HT fonctionnalisé par le triéthoxysilane a permis le greffage direct (« grafting-onto ») sur des oxydes métalliques. L’analyse des propriétés électro-optiques montre un transfert de charge efficace du polymère aux nanoparticules; ce qui suggère que ces matériaux sont des candidats potentiels pour l'application photovoltaïque. Dans la deuxième partie, nous avons montré pour la première fois, l’élaboration de brosses de polymères dits à faible bande interdite sur des surfaces d’oxydes métalliques par la technique « grafting-through ». Une densité de greffage élevée, un meilleur empilement des chaines de polymères et des propriétés optiques améliorées ont été obtenus grâce à la technique de greffage et aux caractéristiques du polymère greffé. Enfin, des brosses de P3HT ont été élaborées sur la surface d’oxyde d'indium et d’étain (ITO) en tant que couche de transport de trous de cellules solaires organiques. Les performances photovoltaïques ont montré que les monocouches auto-assemblées de P3HT (SAM) peuvent être une alternative au PEDOT: PSS

A series of crosslinkable maleimide/thiophene based conjugated polymers with different contents of hydroxyl group containing side chains have been synthesized by the Suzuki coupling reaction. The crosslinkable maleimide/thiophene based conjugated polymers (TM2C41, TM2C21, TM6C41, TM6C21) were reaction with 3,3''-dimethyl-4, 4''-biphenylene diisocyanate by thermal crosslinked in solution state to formed cross-linked polymers (STM2C41, STM2C21, STM6C41, STM6C21), and cross-linked in film solid state to formed cross-linked polymers (FTM2C41, FTM2C21, FTM6C41, FTM6C21), respectively. The chemical structures and crosslinking degree of the maleimide/thiophene based conjugated polymers were identified by the 1H-NMR spectroscopy. The solubility, thermal stability, optical properties, electrochemical properties, and surface morphology of polymer thin films were also studied in the work. Excellent thermal stability was observed for maleimide/thiophene based crosslinked polymers. Polymer solar cells (PSCs) were fabricated from the blends of the conjugated polymer and fullerene derivative (PCBM). The PSCs based on the solution state crosslinked polymers (STM2C41, STM2C21, STM6C41, STM6C21) exhibited power conversion efficiencies of 0.115, 0.118, 0.047, 0.072 %, respectively. The solid state crosslinked polymers (FTM2C41, FTM2C21, FTM6C41, FTM6C21) exhibited power conversion efficiencies of 0.051, 0.050, 0.038, 0.042 %, respectively. As compared to the linear polymer based PSCs, the crosslinked polymer based PSCs show a better operational stability due to the rigid imide rings in the backbone and high morphology stability of the photo-active layer.

In recent years, polymer solar cells (PSCs) have been attracting considerable attention for many advantages, such as low cost, light weight, easy fabrication and their potential application in large area flexible devices. Since the discovery of the photovoltaic effect in bulk heterojunction (BHJ) devices, the considerable publications in PSCs have been reported. PSCs based on the concept of bulk heterojunction (BHJ) configuration where an active layer comprises of a p-type donor (conjugated polymer) and an n-type acceptor (fullerene derivative) materials, represents the most useful strategy to maximize the internal donor-acceptor interface area allowing for efficient charge separation. The goal of this research is to design and synthesize a series of new p-type conjugated polymers to achieve highly efficient BHJ solar cells. Six new cross-conjugated and low bad-gap copolymers have been synthesized and characterized. These of three-component donor-acceptor random copolymers are symbolized as (thiophene donor)m-(thiophene acceptor)n. The PCSTBT series are prepared by Stille coupling polymerization of 2,5-bis(trimethylstannyl)thiophene D1 with 1,4-dibromo-2,5-{bis(4-[N,N-(dioctylamino)styryl])}-benzene) D2 and4,7-dibromo-1,2,3-benzothiadiazole A1, while PCSTDPP series are prepared by Stille coupling polymerization of 2,5-bis(trimethylstannyl)thiophene D1 with1,4-dibromo-2,5-{bis(4-[N,N-(dioctylamino)styryl])}-benzene) D2 and3,6-di(2-bromothien-5-yl)-2,5-dioctylpyrrolo[3,4-c]pyrrole-1,4-dione A2. Thesynthesized copolymers are soluble in common organic solvents and possess good thermal stability. The UV-vis absorption spectra of these copolymers contain an intramolecular charge transfer (ICT) transition band, which lead to an absorption extending into near-infrared region and optical band gaps ranging from 1.36 eV to 1.75 eV. Polymer solar cells of a BHJ were fabricated with the structure of ITO/PEDOT:PSS/Copolymer:PCBM(1:2, w/w)/Ca/Al. The PCE were 0.10 % (PCSTBT25), 0.18 % (PCSTBT50), 0.32 % (PCSTBT75), 0.37 % (PCSTDPP25), 0.54 % (PCSTDPP50), 0.62 % (PCSTDPP75). The higher PCE for PCSTDPP75 copolymer solar cell is attributed to the low band gap of this copolymer compared to others, which increases the numbers of photogenerated excitons and corresponding photocurrent of device. Although their PCE is still relatively low, further improvement on device performance can be achieved through morphology control by thermal annealing and chemical annealing, and carefully device engineering.
