Abstract:
The developments in halide perovskite research target the next era of semiconductors. Photovoltaic solar cells are only one of the technologies that could be exploiting the potential of perovskites soon. Stability and toxicity are two critical aspects of photovoltaic applications because of the long-lasting lifetime and large volumes of the targeted technologies, such as multijunction solar cells with high power conversion efficiency. In this Perspective piece, I discuss how stability and toxicity can be addressed now, incentivizing the research toward lead-free and low-lead formulations. Recent works demonstrated that tin is a possible way out of the toxicity and stability issues of current perovskite formulations. I give speculative directions for stable tin-based perovskite solar cells.
