Chip-scale solar energy harvester delivers 0.75 to 9 V #solar #green

Sol Chip Ltd. (Haifa, Israel) has begun offering an energy harvester photovoltaic cell chip, the Saturn 100, that produces six selectable voltages from 0.75 volts to 9 volts. Sol Chip, founded in 2009, has a technology that enables the integration of standard solar energy conversion technology with established very large scale integration (VLSI) technology. Although this could allow fine-grained solar conversion one of the primary applications is expected to be as an energy harvest device that extracts energy from office lighting and uses a capacitor for storage to provide a 24-hour power source. The maximum power that can be extracted in full daylight from the company's first chip is 4 mW and in office lighting the power extracted is up to 5 µW. The size of the die is not publicly declared on the company website but it would appear to be about 1cm by 1cm. Additional volta...
