Abstract

We report a robust method of hot addition (HAM) to prepare methylammonium lead trichloride (MAPbCl3) and Mn-doped MAPbCl3 (Mn:MAPbCl3) perovskite nanocrystals (PeNCs) for application in luminescent solar concentrators (LSCs). The HAM, which is free of solvent and operates at high temperatures, is applicable to the synthesis of highly crystalline and stable organic-inorganic PeNCs with tunable optical properties. The Mn:MAPbCl3 PeNCs showed a remarkable energy-transfer shift from 400 to 600 nm that enhanced the optical efficiency when these PeNCs were incorporated in an LSC with a silicon solar-cell module. An optical efficiency (OE) greater than 8% was achieved on incorporation of only 0.094 mass % Mn:MAPbCl3 PeNCs in the LSC. A Monte-Carlo ray-tracing simulation was developed to improve the understanding of the experimental results and estimate the ultimate device performance for future application in building-integrated photovoltaic devices.
