Resumen
In order to manufacture an intermediate-band solar cell, it is necessary to connect the intermediate band material (1) with an n-type semiconductor (2) and another p-type semiconductor (3), which will act as emitters. Said emitters must have external contact (4). In comparison with the traditional design of superimposed layers, the present invention proposes a lateral configuration, the 3 different materials being arranged horizontally across a support substrate. Said configuration solves the problem of thermal instability of the B1 material manufactured by ion implantation and the effect of implantation tails.
