Columbia University scientists have designed organic molecules capable of generating two excitons per photon of light. The process is called singlet fission. Of importance is the excitons can live for much longer than those generated from their inorganic counterparts, which leads to an amplification of electricity generated per photon that is absorbed by a solar […]

New research under way at the Universities of Birmingham and Utrecht seeks the secret to the next generation of organic solar cells from tiny fluorescing light-emitting microalgae found in the ocean. Microalgae are probably the oldest surviving living organisms on the planet. They have evolved over billions of years to possess light harvesting systems that […]

A Helmholtz-Zentrum Berlin für Materialien und Energie team has succeeded in producing inorganic perovskite thin films at moderate temperatures using co-evaporation – making post-tempering at high temperatures unnecessary. The process makes it much easier to produce thin-film solar cells from this material. In comparison to metal-organic hybrid perovskites, inorganic perovskites are more thermally stable. The […]

Kanazawa University researchers have documented a new method for controlling the orientation of conducting molecules in organic solar cells that results in the enhanced light adsorption and performance of the cells. Solar cells are an alternate source of energy. A subtype of these, organic solar cells, make use of organic polymers inside the cell. Using […]

Scientists from the Energy Materials and Surface Sciences Unit at the Okinawa Institute of Science and Technology Graduate University (OIST) believe they’ve found a winning formula in a new method to fabricate low-cost high-efficiency solar cells. Professor Yabing Qi and his team from OIST in collaboration with Professor Shengzhong Liu from Shaanxi Normal University, China, […]
