A review paper in Solar RRL on Lead-Less Halide Perovskite Solar Cell by L. Gollino

The rise and commercialization of perovskite solar cells (PSCs) is hindered by the toxicity of lead present in the perovskites employed as the solar light absorber. To counter this problem, lead can be fully (lead-free) or partially (lead-less)

replaced by diverse elements or molecules. Liam Gollino and Thierry Pauporté have just published a review paper which summarize the various strategies employed by the scientific community to reduce the lead content in PSCs. The present achievements and the outlook of those strategies are presented and discussed.

A new article by D. Zheng in J. Mater Chem. A

The roles of mixed ammonium chloride and potassium chloride additives on the growth of Cs0.1FA0.9PbI3 perovskite film is investigated along with the surface treatment by a n-propylammonium iodide solution which produces an interfacial buffer layer. The optimized perovskite solar cell reaches a stabilized power conversion efficiency over 21%.

A review paper on halides and pseudohalides additives for efficient and stable perovskite solar cells was published in ChemSusChem by F. Cheng

Progresses made on the employment of halide and pseudo-halide additives in organo-metal perovskite solar cells are reviewed.

Their function in morphology adjusting, phase stabilizing, energy-level adjusting, trap state passivation and hysteresis elimination are detailed. A deep understanding of the relationship between halide/pseudohalide additive and the improved properties of perovskite solar cell is presented.
