Highly transparent and semi-transparent perovskites and their applications

Perovskite has recently garnered significant attention as a promising semiconductor for optoelectronic applications and particularly for solar cells. In various applications, solar cells must be semi-transparent or even nearly fully transparent. Perovskite solar cells emerge as strong contenders to meet this requirement, owing to their remarkable versatility that allows for high transparency. Consequently, numerous studies on semi-transparent perovskite have been presented in recent years, demonstrating significant advancements in their properties. This review aims to explore color-neutral highly transparent and semi-transparent perovskite solar cells, encompassing their synthetic routes, challenges associated with their fabrication process, and potential solutions. The incorporation of potential additives or two-dimensional perovskites to enhance the properties of semi-transparent perovskite solar cells is also discussed. Finally, we will delve into some promising applications of semi-transparent perovskite solar cells and other applications that have been successfully studied.
