Investigation on characteristics of solar cells made of MOPPV/ZnSe quantum dots composite system∗
摘要
Abstract
Based on some special physical properties of solar cells prepared from quantum dots polymeric materials, which have high photoelectric conversion performance, we use MOPPV solution for obtaining controllable grain sizes, good crystallinity, with a particle size of about 3.75 nm ZnSe quantum dot polymer composite materials, and different quality ratios of the composites. We also use XRD, TEM, UV-vis absorption spectra to study the characterizstics of the materials. The result shows that MOPPV and ZnSe quantum dots have effectively combined together and photoinduced charge transfer. Through the study of MOPPV, ZnSe, and MOPPV/ZnSe composite materal solar cell performance, we found that the composites exhibit an increasing trend compared with MOPPV, ZnSe monomer material photovoltaic characteristics, and the photoelectric properties of the composites showed an increase at first and then reduced with increasing quality of ZnSe quantum dots;when the ratio of MOPPV and the quality of the ZnSe is 1:1, its conversion efficiency reaches a maximum, The Voc, Isc, FF and conversion efficiency of solar cells were 0.516 V, 2.018 mA, 25.53%, and 0.167%.关键词
