Doping Strategies for Promising Organic-Inorganic Halide Perovskites

Organic-inorganic halide perovskites (OIHPs) obtained tremendous attention due to their low cost and excellent properties. However, the stability and toxicity of Pb-based OIHPs (POIHPs), as well as the weakness of efficiency and stability in Sn-based OIHPs (SOIHPs), are still serious issues for commercial application. Notably, composition engineering is an effective and direct strategy for improving these issues along with the control and modification of properties. Recently, the doping strategies for POIHPs and SOIHPs are booming. Based on the relationship between properties and composition, the doping strategies for POIHPs and SOIHPs, aiming to provide a comprehensive review and guidance for the research are systematically summarized. Moreover, the doping strategies for Pb-Sn mixed OIHPs are also discussed. Finally, a brief perspective and conclusion toward future possible doping schemes and properties designment of POIHPs and SOIHPs are offered.

Automated summary

Organic-inorganic halide perovskites (OIHPs) have attracted tremendous attention due to their low cost and excellent properties. However, stability and toxicity issues in lead-based OIHPs (POIHPs) and efficiency and stability weaknesses in tin-based OIHPs (SOIHPs) have hindered their commercial application. Doping strategies for both POIHPs and SOIHPs have shown promising potential in improving these issues. This review systematically summarizes the doping strategies and provides guidance for future research, as well as discussing the doping strategies for Pb-Sn mixed OIHPs.
