Researchers in China have developed a smart solar window tech based on a photovoltachromic device that is able to achieve a high pristine transmittance and to be self-adaptable to control indoor brightness and temperature. The device was assembled via a full solution process in an architecture incorporating glass, a fluorine-doped tin oxide (FTO) layer, a perovskite-based PV cell, an electrochromic gel, another FTO layer, and glass.
Developed by Chinese researchers, the novel design methodology consists of utilizing metal brackets as mounting structures, conventional solar panels, and a grooved glass plate placed between the solar panels. According to its creators, it ensures a farmer’s average income increases by 5.14 times, including the solar power generation business. A system built with this approach should cost around €715 per kW installed.
