Towards more efficient, non-toxic, and flexible thin-film solar cells

Climate change, one of the major global concerns today, has made it clear that fossil fuels are detrimental to our environment and are not a sustainable source of energy. It is imperative to adopt clean sources of energy, and solar cells are a popular candidate on this front. While efficiency is a primary concern for solar cells, researchers have also focused on developing solar cells that are lightweight, low-cost, and flexible. However, the fabrication process itself has posed a serious environmental concern: specifically, the use of toxic materials and generation of industrial waste.
