Quantum dot solar cells and the search for stability
In various forms, quantum dot technology has attracted plenty of attention among PV researchers recently. And as efficiencies have crept past the 15% mark, the community is beginning to look at other factors limiting the viability of quantum dot solar cells in a commercial setting. Scientists in Germany examined the degradation mechanisms affecting different quantum dot materials; and suggest a standardization of stability testing to enable comparability of results.Almost exactly one year ago, scientists at Australia s University of Queensland demonstrated a quantum dot solar cell at 16.6% efficiency, .

DESCRIPTION:
CHARLOTTE, N.C. and MAUNA KEA, Hawaii /3BL Media/ - Duke Energy’s REC Solar and W. M. Keck Observatory have completed the world’s largest commercial solar system installed at the record-breaking altitude of 13,600 feet.
The rooftop solar project – located near the summit of Mauna Kea, a dormant volcano on the Big Island of Hawaii – will reduce Keck Observatory’s carbon footprint and lower its cost of energy.
The solar photovoltaic (PV) system is located on the rooftop of Keck Observatory’s telescope facility, between the domes of the twin Keck I and Keck II – among the world’s largest optical and infrared telescopes. The system will annually produce 259.1 MWh of energy, which will reduce the observatory’s electric power needs by about 10-15% and eliminate 183 metric tons of carbon emissions.
The Solar Together scheme offers residents the opportunity to buy solar panels at a discounted rate through a group buying scheme, with Richmond Council the latest to join.
Atlantic Wind & Solar Inc.: Atlantic Wind & Solar Completes Formation of KBI s New Sustainable Divisions
Formation of new divisions to meet the ever-expanding demand for Next Generation Infrastructure Needs

First attempt to fabricate solar cells based on antimony selenoiodide
South Korean scientists have produced a solar cell based on antimony selenoiodide, with a 4.1% efficiency, a short-circuit current density of 14.8 mA cm2, an open-circuit voltage of 473.0 mV, and a fill factor of 58.7%. They claim the cell exhibits excellent stability in humid conditions.Researchers at South Korea s Ulsan National Institute of Science and Technology (UNIST) have tried to build a solar cell based on antimony selenoiodide (SbSeI). SbSeI is a ferroelectric photoconductor compound that has promising optical properties. It has been applied with success in various optoelectronic applications, .
