Meiji Renewable Energy Laboratory (MREL) has been newly established in 2014 by reconstructing former Solar Cell Research Unit. This Lab is founded by a “bottom-up” manner which is rare case in Meiji Univ. As the start of the Lab, the research area also has been expanded form the mostly concentrating on the energy creation by the solar cells to more widely whole technical issues of the next generation energy including energy storage and saving. Therefore, our research subjects are the energy creation, saving, and storage. We believe that we have to keep efforts to balance them appropriately to generate a synergy.
