Perovskite Photovoltaics for Artificial Light Harvesting

Abstract

Perovskites have encountered a growing interest as light-absorbing materials for harvesting and recycling ambient light. This interest comes from the distinct and impressive intrinsic properties of these materials and is necessitated by the need for reliable and sustainable power supplies for wearable and portable internet of things (IoT) applications. Perovskite artificial light cells (PALCs; i. e., indoor perovskite photovoltaics) have been intensively explored, and thus their device performance has been rapidly augmented. In this review, we summarize and consolidate the research outputs of PALCs by focusing on the tuning of photo-absorber and interlayer materials for efficient harvest and collection of artificial light sources. We also emphasize various challenges and possible future research directions that should be addressed for realizing a large market uptake of PALCs.
