Photovoltaic Thermal Management in Luminescent Solar Concentrators

Cesium Copper Halide Perovskite Nanocrystal-Based Photon-Managing Devices for Enhanced Ultraviolet Photon Harvesting

“…This is mainly due to the dimension limitation of the mounted PV cells and their low efficiency for the high-energy UV photon collection and conversion. ,, In particular, the solar radiation in space consists of ∼7% UV light of the total solar spectrum, i.e., 0.45% UVC (100–280 nm), 1.12% UVB (280–315 nm), and 5.43% UVA (315–400 nm) photons, which is ∼2.5 times more than the total UV radiation on the earth’s surface (due to the strong UV absorption and scattering effects by the ozone layer). , Therefore, desirable lightweight photon-managing devices are pressingly needed to boost the specific power, especially by more efficiently harvesting high-energy UV photons through aerospace satellite systems. In this regard, luminescent solar concentrator (LSC) is a dielectric device that can harvest, direct, and concentrate incoming photons to small areas for the use of energy conversion by the attached PV cells. − And the luminescent downshifting (LDS) layer can be directly attached to PV top surface to improve the short-wavelength response of PV modules by downconverting high-energy photons to a longer wavelength range. − The integration of LSC or LDS devices has been proposed as a potential solution for boosting the solar energy harvesting and increasing the specific power of space-based solar panels. ,− …”
