Advances in lead-free perovskite phototransistors

Abstract

Perovskites have been a popular research focus in the solar cell industry for the previous two decades for its high efficiency and low cost. Recently, the interest in perovskites have expanded into other electrical devices that include phototransistors. With increasing environmental concern regarding perovskite toxicity, lead-free perovskites have become a large focus in research. This review highlights recent research of different lead-free perovskites and gives insight into their effectiveness as phototransistors
