Producing a maximum 300mw in a 27cm square, 0.8mm thick, this lightweight panel just announced by Sharp looks interesting and gives an indication of where we are in small consumer-focused solar panels.
This newly developed solar module makes effective use of compact semiconductor packaging technology to achieve a thickness of just 0.8 mm, the thinnest level in the industry. The solar cells that make up the module are based on polycrystalline silicon and deliver a maximum power of 300 mW*1 , and as an auxiliary power source for mobile devices, will contribute to saving energy. In addition, the electrode pattern on the cell surface can be formed to meet the requirements of device manufacturers, leading to increased design flexibility for mobile devices.
We’re still at a very poor level of efficieny though. 11% efficiency by my reconing. It’s no wonder they didn’t put that statistic in the press release!
300mw is enough to keep a very basic mobile phone topped up while in standby.
