A Review of Perovskite Nanocrystal Applications in Luminescent Solar Concentrators

Abstract

Luminescent solar concentrators (LSCs) are capable of absorbing solar light over a large area, which subsequently converts light into luminescence at a red-shifted wavelength and then redirects it to a smaller target to increase the per-unit yield of photovoltaic devices. Among various LSC materials, perovskite nanocrystals (NCs) have attracted great attention due to their adjustable band gap, multi-exciton effect, and good stability. In this review, a brief introduction of LSCs, including their advances and principles, is given, followed by a summary of perovskite-NCs-based LSCs. The selected examples for component optimization of inorganic perovskite NCs are outlined after an introduction to the structure and properties of perovskite NCs. The absorption and/or emission peaks of all-inorganic and inorganic–organic hybrid perovskite NCs can be efficiently regulated, which not only increases the Stokes shift but also improves the stability. Excellent performance and operability show a bright application prospect of perovskite NCs in the field of LSC applications.
