|- Achieved power conversion efficiency of 11.7%, the highest in the world! -
All eyes are focused on phtovoltaics (solar cells) as the clean, sustainable, and safe energy source. From the founding of our company, we have utilized organic compounds which combine ordinary carbon, hydrogen, and oxygen, to produce numerous products such as functional pigments, organic electrophotographic photoconductors, etc. Currently, leveraging the technology knowledge base in Mitsubishi Chemical, development for the solution-processable organic thin-film photovoltaics (OPV=Organic Photovoltaics) are in progress. OPV is made by applying a coating of organic semiconductor material onto thin plastic or metal substrates. It is possible to manufacture “flexible and light” devices and even devices with three dimensional curved surfaces. This expands the range of devices where the photovoltaics can be implemented. In order to apply this technology to practical uses, we have conducted end-to-end research from molecular design to device manufacturing, and as a result, we have achieved the power conversion efficiency of 11.7% currently and proved the high potential of OPV.
