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.
