Alta Devices’ gallium arsenide solar research cells have been certified with a 29.1% efficiency, setting a new single junction solar cell efficiency record. The most significant change, however, isn’t actually the efficiency; it is that the weight fell 30%, and from the words of Alta Devices, its process has lowered material costs to “essentially nothing”.
Con Edison states that it has become the number two solar power generator in North America with the finalization of its Sempra purchase which included 980 MWac of operating solar.
NREL has proposed a new methodology for determining solar module degradation rates, taking into account measurement challenges such as sensor drift, inverter nuances, soiling and others – keeping the focus on the solar modules themselves.
A University of Michigan team hopes to offer a 15% efficient solar window product, which allows 50% of the light through. It has received US$1.3 million from the Department of Energy’s Solar Energy Technologies Office to develop the idea further.
Lazard’s newly released Levelized Cost of Energy Analysis 12.0, and Storage 4.0, finds that where utility scale wind works, it dominates – and that the unsubsidized cost to build new utility wind and solar facilities is equal to, and often less than running already-built fossil facilities.
Enphase’s 3rd quarter results saw revenues at $78 million with an estimated $10 million sales shortfall due to a component shortage, as the company shipped 204 MW of inverters. Future speculation saw an international play on the IQ8, the SunPower partnership, and energy storage driving growth.
Researchers at the University of Amsterdam have found what they describe conclusive evidence that perovskites feature “efficient carrier multiplication,” effectively increasing the single layer efficiency limit from 33% to 44%.
