Tokyo, Japan [RenewableEnergyWorld.com] Mitsubishi Corporation (MC), the National Institute of Advanced Industrial Science and Technology (AIST) and Tokki Corporation (TOKKI) say they have developed a new, highly-integrated Organic Photovoltaics (OPV) module.
The new module uses laser-scribing technology on a glass substrate. Organic semiconductor materials are deposited on the substrate and then divided into several cells with the laser. The technology eliminates the need for, deposition mask patterning, which is used in conventional methods.
The new module is also highly integrated and should improve sunlight conversion efficiency, Mitsubishi says, adding that the partners believe they have developed a technology to address the low efficiency previously associated with the use of organic materials to make thin-film PV modules.
OPVs are expected to be used in windows, walls, cloths, textiles, outdoor equipment and toys. These applications have proven difficult for the silicon type of PV modules currently in use, and the hope is that OPVs will be more effective. Until now, however, the efficiency of OPVs has been a problem.
The companies have been conducting a Joint Research and Development project for OPVs since 2008.
