Abstract
Transparent energy-harvesting windows are emerging as practical building-integrated photovoltaics
(BIPV), capable of generating electricity while simultaneously reducing heating and cooling demands.
By incorporating spectrally-selective diffraction gratings as light deflecting structures of high visible
transparency into lamination interlayers and using improved spectrally-selective thin-film coatings,
most of the visible solar radiation can be transmitted through the glass windows with minimum
attenuation. At the same time, the ultraviolet (UV) and a part of incident solar infrared (IR) radiation
energy are converted and/or deflected geometrically towards the panel edge for collection by CuInSe2
solar cells. Experimental results show power conversion efficiencies in excess of 3.04% in 10 cm × 10 cm
vertically-placed clear glass panels facing direct sunlight, and up to 2.08% in 50 cm × 50 cm installationready
framed window systems. These results confirm the emergence of a new class of solar window
system ready for industrial application.
