Field: Semiconductors (Electrical engineering)
Classification: CPC H  G  Y | IPC G  H

Claim 9:
10. A photovoltaic device comprising:
a multi-PV cell group having a first PV cell of a first cell type and a second PV cell of a second cell type, wherein the first cell type and the second cell type differ from one another and wherein the first PV cell provides an electric cell voltage U1 and the second PV cell provides an electric cell voltage U2 under light incidence;
a first power electronics unit that is assigned to the first PV cell;
a second power electronics unit separate from the first power electronics unit and assigned to the second PV cell, wherein the electric cell voltage U1, U2 generated in the respective first PV cell and the second PV cell and a corresponding current yield I1, I2 are fed to the separate first power electronics unit and second power electronics unit assigned to the respective first PV cell and the second PV cell;
a control device for separately controlling the first power electronics unit and the second power electronics unit, the control device including a first controller and an independent second controller;
wherein
the first power electronics unit and the second power electronics unit operate independently of one another by way of the first controller and the second controller such that each of the first PV cell and the second PV cell operates at its optimum operating point.
