Lead-free tin-halide perovskite solar cells with 13% efficiency
, 2020 Despite the similarities of the optoelectronic properties between tin halide and lead halide perovskites, the performance of tin perovskite solar cells (PSCs) is still far below that of lead PSCs with highest reported efficiency to date of around 10 ...

Generation of Alkyl Radicals: From the Tyranny of Tin to the Photon Democracy
Chemical Reviews, 2020 Alkyl radicals are key intermediates in organic synthesis. Their classic generation from alkyl halides has a severe drawback due to the employment of toxic tin hydrides to the point that “flight from the tyranny of tin” in radical processes was ...
