Semiconductor device comprising a solar cell, method of manufacturing a semiconductor device and apparatus comprising a semiconductor device

Abstract

The invention relates to a semiconductor device includes a substrate (1000; 2000), a solar cell (1910; 2910) formed on the substrate (1000; 2000) and a battery (1900; 2900) formed on the substrate, the battery comprising a plurality of trench batteries in a plurality of corresponding trenches (1400; 2400) in the substrate (1000; 2000). The solar cell can include a silicon solar cell (1910) comprising a plurality of p-n junctions for, during use, receiving incident light and converting at least part of the received incident light into an electrical current. Alternatively, the solar cell can include an electrochemical cell (2910) for, during use, receiving incident light and converting at least part of the received incident light into an electrical current. The invention further relates to a manufacturing method for a semiconductor device. The invention further relates to an apparatus comprising a semiconductor device.
