Los Alamos National Laboratory researchers have developed new quantum dot solar cells that match the efficiency of existing quantum-dot based devices, but without lead or other toxic elements relied on by most solar cells of this type. Victor Klimov, a physicist specializing in semiconductor nanocrystals at Los Alamos and lead author of the report featured […]

A Rensselaer Polytechnic Institute team of engineers, material scientists, and physicists have demonstrated how a new material – a lead-free chalcogenide perovskite – that hadn’t previously been considered for use in solar cells could provide a safer and more effective option than others that are commonly considered. A widespread transition to solar energy will depend […]

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 […]

Okinawa Institute of Science and Technology (OIST) Graduate University researchers have improved perovskite-based technology in the entire energy cycle. The progress ranges from solar cells harnessing power to LED diodes to light the screens of future electronic devices and other lighting applications. Perovskite is a naturally occurring mineral, but the perovskite used in today’s technology […]

Georgia Institute of Technology researchers have devised a new low-temperature solution printing technique allows fabrication of high-efficiency perovskite solar cells. The technique uses large crystals intended to minimize current-robbing grain boundaries. The meniscus-assisted solution printing (MASP) technique boosts power conversion efficiencies to nearly 20 percent by controlling crystal size and orientation. The process, which uses […]
