ZnO/Cu2O光伏器件性能的模拟研究
Simulation Study on Performance of ZnO/Cu2O Photovoltaic Devices
摘要
Abstract
To explore the working mechanism and the main factors on the power conversion efficiency of n-ZnO/ p-Cu2O heterojunction photovoltaic devices,we simulated the photovoltaic performance of ZnO/Cu2O heterojunction devices by using Analysis of Microelectronic and Photonic Structures-one Dimensional software.The devices performances were systematically analyzed through adjusting the thickness and donor number density of ZnO,the thickness and acceptor number density of Cu2O,as well as the back electrode work function.The results reveal that the power conversion efficiency of the optimized devices can reach 16.9％ when the thickness and donor number density of ZnO are 200 nm and 1× 1019 cm-3,the thickness and acceptor number density of Cu2O are 9 500 nm and 1× 1019 cm-3 respectively,and the back electrode work function is higher than 4.8 eV.The influences of defects on devices performance were also analyzed by adding body defects in Cu2O and interface defects at ZnO/Cu2O interface.The conversion efficiency will deteriorate rapidly when the body defect density of Cu2O is more than i x 1017 cm-3 or the interface defect density is more than 1 × 1012 cm-2.Thus it is extremely important to decrease body defects of Cu2O and treat interface defects to achieve high conversion efficiency.关键词
