Chalcogenide perovskites—challenges, status, and future prospects

This is the authors' abstract. We don't add key points for this paper.

Perovskites dominate the photovoltaic research community over the last two decades due to its very high absorption coefficient, electron and hole mobility. However, most of the reported solar cells constitute organic perovskites which offer very high efficiency but are highly unstable. Chalcogenide perovskites like BaZrS3, CaZrS3, etc. promise to be a perfect alternate owing to its high stability and mobilities. But, till now no stable photovoltaic device has been successfully fabricated using these materials and the existing challenges present in the synthesis of such perovskites are discussed. Also, the basic thermodynamic aspects that are essential for formation of BaZrS3 are discussed. An extensive review on the precedent literatures and the future direction in the BaZrS3 photovoltaic device research is clearly given.
