We describe an approach to solar downconversion in which a semiconductor is used for absorption, and substitutional rare earth ions are used for emission. The semiconductor would provide broad-band absorption, and the rare earth ions would provide em

The surface reflectance of low-iron soda-lime glass imposes a 4% power loss in most flat plate modules. Optical coatings and surface textures are two approaches to decreasing this loss. In this paper we report on a third method comprising ion implant
