The J-aggregates and the photosensitive properties of two kinds of mixed cyanine dye and the corresponding independent cyanine dyes absorbed on AgBr cubic microcrystal were investigated. The reflection spectra of the J-aggregates of the mixed cyanine dyes and the corresponding independent cyanine dyes were measured by the use of UV-Vis spectroscopy. The results showed that the absorption band of the mixed J-aggregates absorbed on AgBr cubic microcrystal had two-peak wavelengths and accorded with the independent cyanine dyes, respectively. The sensitive performance of the mixed cyanine dyes was much enhanced compared to the corresponding cyanine dyes.

We propose an effective method to fabricate highly efficient organic photovoltaic cells based on poly [N-9"-heptadecanyl-2, 7-carbazole-alt-5,5- (4′7′-di-2-thienyl-2′1′3-b-enzothiadiazole):[6,6] -phenyl C71-butyric acid methyl ester (PCDTBT:PC71BM). A power conversion efficiency of as high as 5.6% and a fill factor of 53.7% are achieved from the optimized cells. The influence of surface morphology of the active layer on the performance of the cells is also investigated. © 2011 Chinese Physical Society and IOP Publishing Ltd.

The effects of insertion of ZnO thin layer on organic solar battery performance with P3HT:PCBM for active layerswere were studied, because of the influence of ZnO reactive functions PCBM conducive to close to the transmission and electronic ZnO low HOMO plays the role of block cavity, thus balance electronic and cavities transmission; In the active layer and Al electrodes between insert 3 nm ZnO thin layer as the cavitation linings and electronic choice layer, making battery efficiency of conversion increased from 2.65% to 3.45%. Bcause ZnO thin layer could improve the active layer internal light field intensity distribution, the active layer absorption was further strengthen, thus the purpose of improving efficiency was achieved.
