Design and performance evaluation of a Micro-CPV system for building integration applications

The present research aims at developing a micro-CPV system with static optical elements designed to be placed at the exterior side of buildings to maximize building integration features. The optical system is formed by two optical media with differentiated Abbe number that are designed to minimize f...
