Solarcell curtain
The two devices are also claimed to have high optical contrasts, excellent light sensitivity, and sufficient energy harvesting and storage.Ī perovskite solar cell technology was chosen, the researchers specified, due to its high photoelectric conversion efficiency, low cost, and mature assembly technique. “Among them, DPV-based ECD exhibited transparent deep blue color, as the light intensity changed, and MPV-based ECD demonstrated transparent-blue-magenta colors, depending on the light intensity.” “The characterizations and tests were performed in indoor and outdoor circumstances,” the Chinese group stated. The researchers sensitized two alkynyl-based viologen gels known as DVP and MPV used them to develop electrochromic materials with stability up to 70,000 cycles. Although these devices are capable of modulating their light absorption under a small driving voltage, the requirement for external electrical supplies causes response-lag. Scientists from the Southern University of Science and Technology, in China, have developed an automatic light-adjusting electrochromic device (ECD) powered by a perovskite solar cell (PSC) which they claim can be applied for all-day intelligent-curtains, and advanced electronic displays.Įlectrochromic devices are able to reversibly change colors in response to an electric field and generally consist of multi-layer structures with transparent conductors, electrochromic films, ion conductors, and ion storage films.
