The scientists reported that placing a solar cell in the back of the OLED absorbed the incident light and internal OLED emission, and then converted the light to electrical power for reuse as a photovoltaic device. The modest, 0.26 percent power-recycling efficiency of the experimental unit might be improved by using more-efficient OLEDs and solar cells, according to the scientists." Very interesting and inventive. Thanks again!!! EGM, thanks for that link! very interesting indeed…especially towards the end

JKE. I am not one to encourage patent infringement, but its very tempting to take it apart and reverse engineer it 'the juakali way' I receive mine tomorrow, will do a quick test of it! I know! JKE.
