The ongoing Internet of Things revolution has led to strong demand for low‐cost, ubiquitous light sensing based on easy‐to‐fabricate, self‐powered photodetectors. While solution‐processable lead‐halide perovskites have raised significant hopes in this regard, toxicity concerns have prompted the search for safer, lead‐free perovskite‐inspired materials (PIMs) with similar optoelectronic potential....
Perovskite‐Inspired Materials
In article number 2106295, Vincenzo Pecunia and co‐workers investigate self‐powered photodetectors comprising antimony‐based perovskite derivatives. 2D embodiments—consisting of sheets of corner‐sharing metal‐halide octahedra—more readily convert light into mobile charges. This enables self‐powered photodetectors with considerably higher performance compared to lower‐dimensional...
