Photovoltaic transducer for obtaining energy from sunlight, uses fluorescent layer to match spectral range of sunlight to sensitivity of photocells

摘要

The transducer includes a photocell arrangement (1) and a fluorescent layer (2). The flat side of the fluorescent layer faces the light-incidence side of the photocell arrangement. The fluorescent material is selected so that the solar radiation is converted into radiation in a spectral range for which the photocells are operating at maximum efficiency. The fluorescent material may contain sub-materials with differing absorption-wavelength ranges.
