Epishine (Linköping, Sweden) and Optiqo (Linköping, Sweden) are cooperating to optimise Optiqo's QlvrBox, which currently operates on batteries, enabling the device to be installed independently of the facility’s infrastructure. This feature offers a great benefit when installing the boxes, however the batteries need to be replaced every 1-3 years. The new version of QlvrBox is developed using Epishine's light energy harvesting solution, and is thus powered by ordinary indoor lighting.
Solliance partners TNO, imec/EnergyVille and the Eindhoven University of Technology, realised an 18.6% efficient highly near infrared transparent perovskite solar cell. When combined in a four terminal tandem configuration with an efficient Panasonic crystalline silicon (c-Si) cell or with a Miasolé flexible CIGS cell, it delivers new record power conversion efficiencies of 28.7% and 27.0%, respectively.
SolarWindow Technologies, Inc. (New York City, New York), developer of transparent liquid coatings and processes for generating electricity on glass and plastics recently announced that it has more than doubled its prior certified performance, also achieving the highest independently-certified power conversion efficiency of previous organic photovoltaic devices fabricated at the U.S. Department of Energy’s National Renewable Energy Laboratory in Golden, Colorado through a cooperative research and development agreement (CRADA).
