摘要
选用CuPc(酞菁酮)为供电子的材料,Alq3(8-羟基喹啉铝)为激子阻挡层,研究了结构为ITO/CuPc(20 nm)/C60(40 nm)/Alq3(x)/Ag(100 nm)的有机太阳能电池(OPV),考察了OPV性能同阻挡层Alq3厚度之间的关系。通过分析发现,OPV效率同有机功能层厚度密切相关,在标准太阳光照条件下,结构为ITO/CuPc(20 nm)/C60(40 nm)/Alq3(x)/Ag(100 nm)的器件效率随着Alq3厚度的增加先增大后变小,当厚度为0 nm时,效率为0.285%;当厚度为2.5 nm时,效率为1.13%;而当厚度为5 nm时,效率为0.569%;当厚度为10 nm时,效率则为0%。
CuPc（Phthalocyanine ketone） and Alq3（8-hydroxyquinoline aluminum） are selected separately as donor materials and exciton blocking layer to study the structure of ITO/CuPc（20 nm）/C60（40 nm）/Alq3（x）/Ag（100 nm） of the organic solar cells（OPV）.The relationship between the OPV property and the thickness of Alq3are discussed.OPV efficiency and the thickness of the organic function are closely related.The structure of ITO/CuPc（20 nm）/C60（40 nm）/Alq3（x）/Ag（100 nm） device efficiency first becomes higher and then lower as the thickness of Alq3becomes smaller,when the thickness is 0 nm,the efficiency is 0.285 %;when the thickness is 2.5 nm,the efficiency is 1.13 %;when the thickness is 5 nm,the efficiency is 0.569 %;10 nm,the efficiency is 0 %.
