Most recent researches have focused on the production of the transparent solar cell (TSC) based on organic materials such as a dye-sensitized solar cell (DSSC). Although they are good candidates to produce very thin solar cells, they suffer from “low-efficiency” and “degradation problem”. Therefore, many of these candidates remain in the experimental scale.
As good news, a team of scientists at the Ulsan National Institute of Science and Technology in South Korea developed a technique of producing tiny holes, “windows”, that let a portion of visible light to pass through the otherwise of the opaque silicon wafer (SW).
They used just 200-micrometer thick SWs which included windows with between 500 nanometers and 100 micrometers in diameter. Windows let a part of visible light to pass from the front side to the rear side and eventually exit from them. Crucially, the researchers were able to size and space the holes throughout the wafer to ensure that light across the visible spectrum could pass through the wafer. This gives the light passing through the solar cells a “neutral” color and prevents the light from adopting a particular color, according to Reneweconomy.
They could be widely used in windows and facades of buildings, BIPV, as well as windshield and roof of your car as a vehicle integrated photovoltaics (VIPV). It is a promising candidate for commercializing in the solar industry, especially net-zero emission buildings and solar cars.
