ABSTRACT
We used p-type CuPc and n-type TPyP to grow up organic solar cells on ITO conductive glass by thermal evaporation. We have fabricated the sample No.S37 which is the best. The structure is ITO/TPyP(100 nm)/TPyP+CuPc(100 nm,2:1)/CuPc(100 nm)/Al.
We also measured this sample and know the ISC=1.73 mA ,VOC=0.73V ,and evaluated fill factor(FF)=86.9% ,efficiency(η)
=0.69%。Finally, we discussed the result what we got to find out the rule: the thick of n-type TPyP is thicker, or the ratio of TPyP in the mixture layer, we could get a better efficiency (η).
Keywords : organic solar cell ; CuPc ; TPyP ; absorption ; efficiency Table of Contents
