摘　　要：基于热蒸镀法制备了超薄透明银(Ag)电极,将其利用在半透明有机太阳能电池中,研究了超薄Ag透明电极的厚度对半透明有机太阳能电池透射率和光伏性能的影响。测试不同厚度Ag透明电极的透射率发现,当Ag电极厚度由15 nm增加到20 nm时,可见光区的透射率逐渐降低。透明Ag电极的厚度在18 nm时,器件在可见光区的平均透射率为23.02%,光电转换效率(PCE)可达到2.70%,比不透光器件的PCE数值3.93%降低21.95%。The ultra-thin transparent silver(Ag)electrodes were prepared by using thermal evaporation method and were used in semi-translucent organic solar cells to study the effects of different thickness of Ag electrodes on the transmittance and photovoltaic characteristics of the cells.The tests of the transmittance of Ag electrodes with different thicknesses showed that the transmittance in the visible region decreased with increase of thickness from 15 nm to 20 nm,and the highest transmittance of the device reached 23.02%when the thickness was 18 nm.Further test results found that the photoelectric conversion efficiency(PCE)reached 2.70%,which was only 21.95%lower than the opaque device with PCE of 3.93%.
