Transparent photovoltaics

Definition

Transparent photovoltaics are solar cells that allow light to pass through while also converting some of that light into electrical energy. This innovative technology combines the functionalities of traditional solar panels with transparency, making it possible to integrate solar energy generation into windows, displays, and other surfaces without obstructing visibility.
