Problems solved by technology

Compared with silicon solar cells, one of the characteristics of compound semiconductor solar cells is that they are resistant to radiation, but because most compound semiconductors are toxic, they are easy to pollute the environment, and the cost is high. Currently, they are mostly used in some special occasions such as the space environment.

Abstract

The invention relates to a method for preparing a solar battery sensitized by utilizing a zinc phthalocyanine bisphenol A epoxide derivative, belonging to the field of a preparation process of the solar battery. The method comprises the following steps: firstly preparing tetranitro zinc phthalocyanine by adopting a phthalic anhydride-urea solvent method; reducing the tetranitro zinc phthalocyanine to tetraamino phthalocyanine through Na2S.9H2O; synthesizing bisphenol A diglycidyl epoxy ether; and reacting diglycidyl epoxy ether with tetraamino phthalocyanine to obtain a zinc phthalocyanine bisphenol A epoxide derivative; and taking the derivative as a dye photosensitizer to sensitize a TiO2 nanocrystal membrane to prepare into the dye sensitized solar battery. The dye photosensitizer is high in fluorescence quantum efficiency and good in light absorption at an ultraviolet band of 300-400nm and an infrared band of 600-800nm. Compared with tetraamino phthalocyanine, the dye sensitized solar battery prepared by the dye is higher in light current, light voltage and photoelectric conversion efficiency.

Description

technical field [0001] The invention relates to a method for preparing a nano-film solar cell sensitized by zinc phthalocyanine bisphenol A epoxy derivatives. The invention belongs to the field of solar cell preparation technology. Background technique [0002] Due to the reduction of traditional fuel energy and the increasingly prominent environmental pollution, the search for clean and renewable energy has become a common concern of all countries in the world. Among them, solar energy has become the best energy source that is safe and pollution-free due to its unique advantages such as inexhaustible, inexhaustible, and not restricted by geographical environment. One of the most attractive alternative energy sources. [0003] From the analysis of the current global solar cell development status, silicon-based solar cell technology is becoming more and more mature, and has been mass-produced worldwide, achieving significant economic and social benefits. However, the hars...
