Description

technical field

[0001] The invention relates to the field of electron transport materials for photovoltaic devices, in particular to a photovoltaic device containing pyridine polymer. Background technique

[0002] As a kind of flexible and printable solar cells, organic solar cells are composed of organic semiconductor materials as the core part of solar cells. They have the advantages of wide source of raw materials, good flexibility, solution processing, and printability. The first organic solar cell was prepared by Kearns and Calvin in 1958. Its main material was magnesium phthalocyanine dye, and the dye layer was sandwiched between two electrodes with different work functions. Through this device, they could observe an open circuit of 200mV voltage, but the photoelectric conversion efficiency is very low. The most widely used solar cell device structure is a "sandwich" structure, which generally includes the following parts: (1) transparent electrode, usually an oxide m...
