Abstract
Wireless networks for novel applications such as the "internet of things" and "smart dust" require the availability of efficient miniaturized power sources for the realization of autonomous sensor nodes. The most common power source currently utilized is the conventional battery. Energy harvesting from ambient light is an efficient alternative way to circumvent the necessity to periodically replace such batteries. In the frame of a customized development Fraunhofer IMS has developed recently a miniaturized photo cell that can be integrated monolithically on a CMOS-substrate, thus enabling the realization of extremely miniaturized sensor nodes. In order to design and optimize such miniaturized solar cells a careful modelling is required. We report on simulation results on the amorphous solar cells based on experimental material parameters and report on comparisons with experimental results.
