Summary:Power generation for the Internet of Things (IoT), particularly wearable electronics, is a significant challenge and a subject of great interest in the field of photovoltaics research. Here, we have designed and fabricated single crystalline silicon solar cells using a single-sided micromachining process. Preliminary results indicate that the solar cell is flexible and ~50% transparent. Furthermore, the open-circuit voltage and the short-circuit current density of the fabricated device under indoor light with the power density of 2 mW.cm -2 are 0.4 V and 110 µA.cm -2 , respectively. The fabricated solar cells have been specifically designed to conformally fit on the commercial contact lenses.
