Performance of perovskite solar cells under simulated temperature-illumination real-world operating conditions
Michael Graetzel, Wolfgang Richard Tress, Ulf Anders Hagfeldt, Konrad Domanski, Essa Awadh R Alharbi, Brian Irving Carlsen, Anand Agarwalla
Since reaching 20% efficiency, research in perovskite photovoltaics has shifted from a race for efficiency to a race for stability. For efficiency, the standard test conditions set the rules for the race. However, the term 'stability' is used very broadly ...
NATURE PUBLISHING GROUP2019How far does the defect tolerance of lead-halide perovskites range? The example of Bi impurities introducing efficient recombination centers
Wolfgang Richard Tress, Simone Meloni, Björn Niesen, Juan-Pablo Correa-Baena, Zaiwei Wang, 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 ...
ROYAL SOC CHEMISTRY2019A chain is as strong as its weakest link - Stability study of MAPbI(3) under light and temperature
Michael Graetzel, Ulf Anders Hagfeldt, Michael Saliba, Pankaj Kumar Yadav, Amita Ummadisingu, Silver Hamill Turren Cruz, Philippe Jürgen Holzhey
The stability of perovskite solar cells is a key issue for industrial development. One reason for this is the volatile organic methylammonium (MA) cation, which is prone to degas under elevated temperatures from the perovskite. At the same time, small amou ...
