pairing of near-ultraviolet solar cells with electrochromic windows for smart management of the solar spectrum - smart

Current smart window technology provides dynamic control over visible and near-visible transmission
The infrared part of the solar spectrum to reduce the need for lighting, heating and cooling in buildings and to improve the comfort of occupants.
Solar cells harvested nearby
UV photons can meet the unmet need to power these smart windows in the same space footprint without competing for visible or infrared photons and without the same aesthetic and design limitations.
