From PV EXPO - Konarka to Release Transparent Solar Cell in 2009

From PV EXPO - Konarka Technologies Inc of the US exhibited a variety of organic thin-film solar cell modules manufactured by roll-to-roll process at the 2nd International Photovoltaic Power Generation Expo (PV EXPO 2009). Taking advantage of their flexibility, some prototypes are attached to a bag and used as a power source of an electronic paper in the exhibition. Konarka's organic thin-film solar cells feature an energy conversion efficiency of 4% in a building and 3 to 4% outside a building, according to the company. The outdoor efficiency is slightly lower because "their high circuit resistance impacts more as current increases," said a spokesperson of Toppan Forms Co Ltd, which shares the booth with Konarka.
