Abstract

La présente invention concerne un verre photovoltaïque à concentration de lumière à motif matriciel (1). Une face du verre est plane, et des unités de lentilles matricielles sont réparties de manière uniforme sur l'autre face du verre, l'unité de lentille étant une unité de lentille de surface sphérique. La projection vers le bas de l'unité de lentille est un carré. Le verre photovoltaïque à concentration de lumière (1) est utilisé pour encapsuler des cellules photovoltaïques solaires à concentration de lumière, ce qui permet de réduire la quantité de plaquettes de silicium (2) utilisées, et ainsi de diminuer les coûts de production de cellules solaires.
