Disclosed is a novel method for creating local contacts in solar cells. The first time interval and the second time interval are repeated alternately. This ensures an increase in area covered with the condenser lens in the pixel region, thereby causing more light rays to enter the condenser lens. Each nozzle has a nozzle inlet, a nozzle outlet, and a nozzle passageway extending between the nozzle inlet and the nozzle outlet. The vector processing array includes a plurality of vector processors which are operable in a single instruction multiple data configuration. In a closed position of the device, the switch is locked.
