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, […]

Hokkaido University scientists have developed a photoelectrode that can harvest 85% of visible light. It is built in a 30 nanometers-thin semiconductor layer sandwiched between gold layers, converting light energy 11 times more efficiently than previous methods. The research team, led by Professor Hiroaki Misawa of the Research Institute for Electronic Science at Hokkaido University, […]

A team of semiconductor researchers based in France has used a boron nitride separation layer to grow indium gallium nitride (InGaN) solar cells that were then lifted off their original sapphire substrate and placed onto a glass substrate. The French team’s technique is the third major application for the hexagonal boron nitride lift-off technique, which […]
