辐照强度及温度对双层异质结有机光伏器件性能的影响
Effects of Illumination Intensity and Temperature on Double-layer Heterojunction Organic Photovoltaic Device Performance
摘要
制备了基于CuPc/C60双层异质结有机光伏器件, 研究不同光辐照强度及温度对器件性能的影响。测试结果表明: 辐照强度直接决定器件的短路电流大小, 但对开路电压影响不大; 器件的短路电流对温度依赖性不强, 但随着温度的降低, 器件的开路电压逐渐增大。结合实验数据从理论上解释了光辐照强度及温度与有机光伏器件短路电流密度和开路电压的关系, 为有机太阳能电池性能的改善提供了研究基础。
Abstract
This article fabricated the CuPc/C60 double-layer heterojunction organic photovoltaic devices, investigated the effects of different illumination intensity and temperature on device performance. The results showed that the illumination density directly determined the value of photocurrent under short circuit condition, while had little effect on the open circuit voltage. The short circuit density had little weak dependence on temperature. The device exhibited larger open circuit voltage with the reduction of temperature. According to the experimental data, This article theoretically analyzed the relationship of illumination intensity, tempe-rature short, circuit density and open circuit voltage, which provided a research foundation for the high performance of organic solar cells.
