Polymer Nanocomposites and Metal Halide Perovskites for Luminescent Solar Concentrator Applications—Host Materials Perspective

Abstract

One of the greatest persuasive classes of photonic devices depending on Stokes shift engineered emitters is the luminescent solar concentrators (LSCs). It has been recently proposed as an effective complement to conventional photovoltaic modules for the understanding of building-integrated photovoltaic (BIPV) devices. Luminescent solar concentrators (LSCs) are capable to proficiently gather solar energy through large‐area photovoltaic windows, where fluorophores are precisely entrenched. Amongst various types of fluorophores, all‐inorganic perovskite nanocrystals (NCs) are considered as an emerging class of absorbers/emitters in LSCs. This is due to their size, composition, dimensionality, tunable optical properties and high photoluminescence quantum yield (PLQY). However, due to the large overlap between absorption and emission domains, it is still challenging to fabricate high‐efficiency LSCs. In this chapter, a new kind of material (metal halide perovskite NC) used to fabricate semi‐transparent and large‐area LSCs will be discussed in detail. Also this chapter will provide information about the potential of doped perovskite NCs for LSCs, as well as for other photonic technologies, that rely on low-attenuation, and long-range optical wave guiding.
