Structural optimization of semitransparent power-generating
Semitransparent window glass with perovskite layers of doped core-shell nanoparticles. Average transmittance and photoelectric conversion efficiency are balanced by
A standardized model is presented for evaluating the efficiency of spectral converters integrated into PV glass, systematically assessing spectral absorption and emission properties, current drop and current gain, material stability, and integration feasibility.
Among the functionalities offered by windows, solar heat gain and visible light transmission represent two vital factors in the energy and environmental performance of buildings. Solar Heat Gain Coefficient (SHGC) is a measure of how much solar energy passes through a window, expressed by a ratio in the range of 0 to 1.
The naturally occurring (and fundamental) trade-off between glass transparency and power generation per unit area is approached differently in systems utilising different energy-conversion materials, resulting in a range of power-vs-transparency options, most of which do not result in colour-free visually-clear appearance.
The advancements in glass technology, such as rare-earth doping and the incorporation of heavy metal oxides, have shown promise in optimizing the solar spectrum for improved energy absorption and conversion.
