“…These cells consist of semiconductive material doped in a single junction, like a diode. Different materials can be used and combined to achieve a similar channel, with distinct properties such as III and V materials [7,17]. Elements such as Cu, Zn, Cd, Al, Ga, In, Si, Ge, P, As, Sb, S, Se and Te are considered semiconductor materials, therefore a P or N junction can be generated when combining these elements in a substrate base.…”
