Here, we report solar cells based on contorted hexabenzocoronene (cHBC) derivatives that selectively harvest near-UV light, and demonstrate their pairing with polymer-based electrochromic windows (ECWs) to modulate the transmission of visible and near-IR light.
Solar cells harvesting near-ultraviolet photons could satisfy the unmet need of powering such smart windows over the same spatial footprint without competing for visible or infrared photons, and without the same aesthetic and design constraints.
These single-junction cHBC-based solar cells exhibit photovoltages exceeding 1.6 V; the high photovoltages of the near-UV cells (relative to typical solar cells) enhances their utility for switching the electrochemical states of ECWs.
This work implicates near-UV solar cells as promising power sources for emerging dual-band smart window technologies to independently regulate visible and near-IR/infrared wavelengths over the same spatial footprint (Fig. 1) 4, 7.
Low-cost, visibly transparent photovoltaic cells (TPVs) can provide local, renewable power to such electrochromic windows 2 without altering building aesthetics or imposing further design constraints.
Integration of these solar cells with a low-cost, polymer-based electrochromic window enables intelligent management of the solar spectrum, with near-ultraviolet photons powering the regulation of visible and near-infrared photons for natural lighting and heating purposes.
