Title
(EN) IMPROVED OPTICAL DESIGN FOR PHOTO-CELL
(FR) AMELIORATIONS APPORTEES A LA CONCEPTION DE L'OPTIQUE DES PHOTOCELLULES
Abstract
(EN) A combination comprising a device (500) for receiving and for directing incoming light (501) in a three dimensional manner to at least one predetermined location together with a solar cell (514) is disclosed. Device (500) has two light reflecting surfaces (504) and (505) and a total internal reflection surface (503). In operation, total internal reflection surface (503) transmits incoming light (501) into device (500) and totally internally reflects light reflected from surface (504) which is incident at its surface at an angle within the range for total internal reflection. Surfaces (504), (505) and (503) are operatively disposed with respect to one another so as to perform the function of a receiver/director by directing incoming light (501) in a three dimensional manner to the rear surface (513) of solar cell (514).
(FR) Une combinaison comprend un dispositif (500) conçu pour recevoir et pour diriger la lumière incidente (501) de manière tri-dimensionnelle, vers au moins un endroit prédéterminé, grâce à une cellule solaire (514). Le dispositif (500) possède deux surfaces de réflexion de la lumière (504 et 505) et une surface de réflexion totale intérieure (503). Lors du fonctionnement, la surface de réflexion totale intérieure (503) transmet la lumière incidente (501) vers le dispositif (500) et réfléchit totalement intérieurement la lumière réfléchie par la surface (504) qui est incidente à sa surface avec un angle compris dans la plage de réflexion interne totale. Les surfaces (504), (505) et (503) sont disposées fonctionnellement les unes par rapport aux autres de manière à effectuer la fonction de récepteur/guide en dirigeant la lumière incidente (501) de manière tri-dimensionnelle vers la surface arrière (513) d'une cellule solaire (514).
