Development of non-toxic and stable perovskites for high efficiency solar cells

The goal of this project is to develop lead-free perovskite light absorbing materials, and use them to construct high efficiency and stable solar cells. In particular, this project focuses on understanding the changes in the optical, electrical, and electronic properties of the bulk materials and thin films of the tin-based perovskite materials upon different preparation approaches. Once a clear understanding of the properties is established, the tin perovskites will be incorporated with other charge transport layers to fabricate devices. Device stability will also be addressed.
