Abstract

La présente invention a trait à des techniques pour la collecte d'une grande quantité de rayonnement solaire sans surchauffe des cellules solaires sous-jacentes. Selon un aspect des techniques, un réseau de lentilles de concentration sont prévues, chacune des lentilles présentant une surface sphérique comportant une pluralité d'anneaux concentriques en forme de V. Il a été démontré que de telles lentilles sont capables de focaliser une grande quantité de rayonnement solaire sur des cellules solaires tout en réduisant la chaleur provoquée par le rayonnement solaire concentré. En vue de favoriser la dissipation de la chaleur, les cellules solaires sont fixées à un panneau métallique. Divers agencements d'électrodes sont conçus pour entraîner vers l'extérieur des signaux d'énergie en présence du panneau métallique.
