How far does the defect tolerance of lead-halide perovskites range? The example of Bi impurities introducing efficient recombination centers

Wolfgang Richard Tress, Simone Meloni, Zaiwei Wang, Björn Niesen, Juan-Pablo Correa-Baena, Chien-Jen Yang, Mozhgan Yavari, Firouzeh Ebadi Garjan

One of the key properties of lead-halide perovskites employed in solar cells is the defect tolerance of the materials, in particular regarding intrinsic point defects, which mainly form shallow traps. Considering that high luminescence yields and photovolt ...

Greener, Nonhalogenated Solvent Systems for Highly Efficient Perovskite Solar Cells

Michael Graetzel, Ulf Anders Hagfeldt, Michael Saliba, Silver Hamill Turren Cruz, Mohammad Mahdi Tavakoli, Mozhgan Yavari

All current highest efficiency perovskite solar cells (PSCs) use highly toxic, halogenated solvents, such as chlorobenzene (CB) or toluene (TLN), in an antisolvent step or as solvent for the hole transporter material (HTM). A more environmentally friendly ...
