Description

【Technical field】 [0001] The invention relates to the field of organic semiconductor materials, in particular to a carbazole-containing porphyrin-triphenylamine copolymer material and its preparation method and application. 【Background technique】 [0002] The preparation of low-cost and high-efficiency solar cells using cheap materials has always been a research hotspot and difficulty in the field of photovoltaics. Due to the complex production process and high cost of traditional silicon cells used for the ground, its application is limited. In order to reduce the cost of batteries and expand the application range, people have been looking for new solar cell materials for a long time. Organic semiconductor materials have attracted much attention due to the advantages of readily available raw materials, low cost, simple preparation process, good environmental stability, and good photovoltaic effect. Since 1992, N.S.Sariciftci etc. reported the light-induced electron transf...
