A METHOD FOR PREPARING A PEROVSKITE SOLAR CELL MODULE BY ROLL-TO-ROLL PRINTING

摘要

A method for preparing a perovskite solar cell module by roll-to-roll printing compri-sing preparing a perovskite solar cell functional layer and a back electrode on a subs-trate by use of a roll-to-roll process with a solar cell production equipment to obtain a perovskite solar cell slice, i.e., a solar cell module. The functional layer comprises a hole transport layer, a perovskite layer and an electron transport layer； wherein th-e solar cell production equipment comprises a near infrared heating system and an a-ir heating system to heat synergistically when the perovskite layer is being prepared. The method can realize automatic, continuous and large-scale production, and can re-alize the efficient and rapid preparation of the perovskite solar cell. The area, size an-d shape of the resulting perovskite modules can be flexibly controlled as required, s-uch that a perovskite solar cell modules can be formed with the benefit of saving raw materials and adapting to the market requirements.
