In order to harness green energy from solar cells multiple cells need to be in series to get their voltage high enough to power conventional electronics. Freescale Semiconductor has developed an integrated mixed signal chip that can convert the output from a single solar cell into a usable power source. Freescale's dc-to-dc power conversion technology, was announced today at the Applied Power Electronics Conference and Exposition (APEC, Feb. 16-19, Washington D.C.) Besides photovoltaic (PV) cells, thermoelectric-generators, electromagnetic-generators and even bioelectric energy can be harvested with Freescale's technology.
