Method for recovering lead in perovskite solar cell

Abstract

The invention discloses a method for recovering lead in a perovskite solar cell. The method comprises the following steps of manually stripping a substrate material, conducting glass and a top electrode; the chemical solvent dissolution method is used for removing the hole transport layer; the lead-containing compound is extracted; and the lead recovery rate, the recovery quality and the recoveryeffect are detected. The toxicity problem of the perovskite solar cell material is solved, the green and environment-friendly effects are ensured in the implementation process, and the pollution problem in the recovery process is avoided.

Description

technical field [0001] The invention discloses a method for recovering lead in a perovskite solar cell, belonging to the technical field of pollutant recovery. Background technique [0002] Among emerging photovoltaic technologies, organolead halide perovskite solar cells with low-temperature and dissolution processing capabilities have received increasing attention in recent years. In addition to continuous progress in efficiency, perovskite solar cells show great promise as a new large-area and cost-competitive photovoltaic technology with good stability. [0003] However, the toxicity of lead in traditional lead-based perovskites has greatly limited the large-scale commercial application of perovskite solar cells. Environmental threats and ecotoxicity caused by the use of the toxic metal lead may hinder perovskite solar cells from becoming a flourishing new photovoltaic technology. Therefore, from the perspective of economy and environmental protection, to realize the w...
