Collector i.e. sunlight collector, for use in building roof for e.g. building-integrated photovoltaic power generation, has substrate units comprising substrate layers and fluorescent material and spatially separated from each other by gap

摘要

The collector (10) has substrate units (12, 14, 16, 18) connected with a solar cell and comprising substrate layers (20, 22, 24, 26) and fluorescent material that is connected with the layers. The substrate units are spatially separated from each other by a gap (40), where end regions of the layers are connected by a spacer. A layer (38) filters the fluorescent material with noxious wavelengths of sunlight (36). The fluorescent material is designed as a dye film on a surface area of the layers, and exhibits gradated absorption or emission spectrum of the adjacent substrate units. An independent claim is also included for a collector arrangement comprising a receptacle.
