Kesterite solar cell coated architectural stainless steel

点击翻译按钮获取中文摘要

This project aims to develop cost-effective, high-performance kesterite architectural stainless steel coated with solar cells for application in roofing, skin and facades of smart buildings. The project will integrate expertise in producing kesterite solar cells with expertise in manufacturing new steel to eliminate toxic, scarce materials and high-cost processes employed in conventional solar-driven steel. The initial target of the project would be to increase kesterite cell efficiency to beyond 10 per cent, and ultimately beyond 17 per cent, but still at a low cost.
