A research team from the Ulsan National Institute of Science and Technology (UNIST) in South Korea has developed transparent solar cell technology capable of directly charging a battery from a glass surface. This innovation offers numerous applications, allowing for direct energy generation from sources like smartphone screens, car windows, and building facades.
Weight is extremely important in automotive applications, and I see no info on how this compares to the weight of conventional auto glass.
Most “solar on cars” doesn’t get past the gimmick stage because of unfavorable power to weight ratio.
