AI Technical Summary
Existing glass curtain walls cannot flexibly adjust the photothermal and electrical properties of sunlight according to the building's dynamic energy needs, resulting in increased heat gain from solar radiation in winter and increased cooling load in summer, and they cannot fully utilize non-lighting spectrum energy.
A dual-mode photothermal and photoelectric thin-film battery, made of dye-sensitized solar cells doped with silver nanoparticles, is integrated into a double-layer curtain wall. By changing the ventilation mode through louvers, flexible control of photothermal and electric power can be achieved, including switching between power generation and heat generation modes.
It enables flexible control of solar thermal power under different seasons and building requirements, improves photoelectric conversion efficiency, reduces building heating and cooling loads, and meets dynamic energy demands.
