Perovskite Quantum Dots Based Luminescent Solar Concentrators

Abstract

Luminescent solar concentrators (LSCs) are emerging technology of current interest as a platform for solar energy harvesting. LSCs can serve as large-area sunlight collectors for photovoltaic cells to reduce the cost of electricity by decreasing the use of expensive photovoltaic materials. Among various types of fluorophores, perovskite quantum dots have been used as light-converters due to their size/shape/composition-tunable wide absorption spectrum, narrow emission spectrum, high quantum yield and structure-engineered large Stokes shift. In this Chapter, we summarized the use of various types of perovskites and different configuration to fabricate high efficiency and large-area LSCs. The optical properties of perovskite are strongly depending on their size, shape and composition. Therefore, one can optimize their structure to obtain the suitable emitters for LSCs. Among various types of perovskites, doped quantum dots offer a great opportunity to synthesize high quality perovskites with both high quantum yield and large Stokes shift, indicating the doped perovskites may be a great candidate as emitters for high efficiency LSCs. We conclude with a detailed account of the latest research progress in synthesis, structure, materials, and performance of LSCs based on perovskite quantum dots and a further perspective on the remaining key issues and open opportunities in the field.
