標題: | Performance enhancement in organic-inorganic hybrid photovoltaic cells by adding a carbon-nanostructure interface layer | 作者: | YANG-FANG CHEN | 公開日期: | 2011 | 起(迄)頁: | 000716-000718 | 來源出版物: | Conference Record of the IEEE Photovoltaic Specialists Conference | 摘要: | Inverted photovoltaic configuration overcomes the stability problem in conventional polymer photovoltaic device. However, the charge transport property at the organic-inorganic junctions is one of the important issues affecting the performance of this type of photovoltaic cells. To solve the problem, we deposit a carbon-nanostructure layer, C 60, on the inorganic ZnO-nanorod array surface to be in contact with a polymer blend, poly(3-hexylthiophene):(6,6)-phenyl C 61 butyric acid methyl ester (P3HT:PCBM), forming a ZnO/C 60/P3HT:PCBM/Ag device. In the presence of the C 60 layer, both the short circuit current (J SC) and open circuit voltages (V OC) are improved leading to an enhancement in the power conversion efficiency from 1.3% to 2.1%. The role of the C 60 layer is to assist the exciton separation and transport the electrons to the collecting electrode. © 2011 IEEE. |
