Eco-friendly Fabrication of Perovskite Solar Cells: From Material Engineering to Recycling

Abstract

Perovskite solar cells (PSCs) are one of the most promising and rapidly developing emerging technologies in the field of photovoltaics. With the high development rate of photovoltaic technology, it is important to be aware of its environmental impact and eco-friendliness. Being a renewable energy harvesting technology, fabrication of PSCs is known to be a green manufacturing method, however, with the recent progress and various fabrication techniques, the environmental impact should be monitored and managed. Therefore, the environmental issues of the manufacturing process from materials design to perovskite deposition and recycling became crucial for their later commercialization. This review provides an outlook on the recent development of PSCs in the context of eco-friendliness and highlights the technology’s low contribution to environmental pollution.
