Solar Window Technology Opens Up
Researchers pioneer new window architecture making solar energy collection more efficient
Aaron Martin, January 4, 2018 (Daily Energy Insider)
“…Researchers have pioneered a double-pane window architecture that incorporates two varieties of designer quantum dots to split and absorb different parts of the solar spectrum. The quantum dots can reduce solar electricity costs by generating electricity more efficiently while providing shading, according to Los Alamos National Laboratory research. The solar-spectrum splitting is the] core element of the breakthrough. It allows for the separation of higher- and lower-energy solar photons. Higher-energy photons are capable of generating a higher photovoltage, which drives total power output…A layer of highly emissive manganese-doped quantum dots are placed on the fronts of glass panes, and copper indium selenide quantum dots are placed on the backs of glass panes. While the manganese-doped quantum dots absorb blue and ultraviolet solar light, the copper indium selenide quantum dots absorb the rest of the spectrum…After absorption, the light is re-emitted to edges of the panes for collection by solar cells.” click here for more
