A photovoltaic skylight is an innovative building-integrated photovoltaic (BIPV) product that combines the functionality of a traditional skylight with solar energy generation. These systems use semi-transparent or transparent solar cells embedded within glass panels to allow natural light to enter a building while simultaneously converting sunlight into electricity. Unlike standard solar panels, photovoltaic skylights are designed to be aesthetically pleasing and architecturally integrated, offering dual benefits: daylighting and renewable energy production. They are commonly installed in commercial buildings, atriums, greenhouses, and residential structures seeking to reduce energy costs and carbon footprints. The technology typically involves thin-film solar cells, crystalline silicon cells with spacing, or advanced transparent luminescent solar concentrators. As energy efficiency regulations tighten globally, photovoltaic skylights are becoming a key component in net-zero building designs.
