A Cambridge team’s hybrid cell—using organic and inorganic materials—generates two electrons for every photon, which could enable a big boost in energy capture.
PV keeps getting better: Alta Devices says its panel registered 23.5 percent efficiency, while Semprius, using concentrated photovoltaics, hit 33.9 percent.
First Solar continues to drive efficiency up (and cost down), with a cadmium-telluride PV solar module checks in at a record 14.4 percent total area efficiency.
Solar3D says that tests of its three-dimensional solar cell design that “traps” sunlight suggest that a prototype could hit 25.47 percent efficiency.
Notre Dame researchers are turning heads with their “Sun-Believable” solar paint, which needs improvement but hints at a cheap and easy way to do photovoltaics.
Texas researchers say they’ve found a way to harvest double the electrons from a photon, increasing the limit for solar cell efficiency to 44 percent.
Berkeley researchers realized that external fluorescence output was the key to building a solar cell that busted the old efficiency records.
