The Stability

ABSTRACTWe report on Cr2O3 layer by thermal evaporation of Cr2O3 powder as cathode interfacial layer to improve the stability in air for the bulk heterojunction solar cells of poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl C61 butyric acid methyl ester (PCBM). Devices with Cr2O3 interfacial layers show higher power conversion efficiency (PCE) and stability than those without interfacial layer. Devices with Cr2O3 show improved stability approximately 100 times than that of devices without interfacial layer or with LiF interfacial layer.

AbstractThe roll-to-roll reverse gravure (RG) coating technique was used to produce thin homogeneous films (∼100 nm) for organic bulk heterojunction solar cells. The conducting polymer poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) and the active layer regioregular poly(3-hexylthiophene-2,5-diyl):[6,6]-phenyl-C61-butyric acid methyl ester (P3HT:PCBM) were successfully subsequently RG coated on an ITO covered plastic substrate in ambient air. Working solar cells were achieved after annealing and thermal evaporation of the top contact. The AM1.5 power conversion efficiency (PCE) of the RG coated organic solar cells was determined to 0.74% (at 100 mW/cm2). This was very similar to the results of a reference device that was spin coated on a glass substrate in a nitrogen glove box.

Pet Substrate

Bulk-heterojunction solar cells were fabricated based on poly(3-hexylthiophene) (P3HT) and [6,6]-phenyl C61 butyric acid methyl ester (PCBM) on an indium tin oxide (ITO) coated flexible polyethylene terephthalate (PET) substrate. Performance improvements of the flexible solar cells by optimizing post thermal annealing conditions are reported. The solar cells annealed at 150 oC showed the minimal deformation of the PET substrate, and the resulted conversion efficiency was 1.35% under the light irradiation conditions of the Superscript textAM1.5 simulated solar intensity of 100 mW/cm2.
