Gallium arsenide phosphide tandem solar cell with 25.0% efficiency
The demonstrated device, according to the academics, is built with interfaces between the active cell layers that improve the top cell carrier collection. The cell was built with texturing and a hydrogenated amorphous silicon (a-Si:H) passivation of a silicon back surface.
Financial closing for 82 MW of PV in Guinea
German developer Clean Power Generation will build three PV plants in two different parts of the West African nation. All of the projects will sell electricity to state-owned utility Electricité De Guinée.
US residential solar set for a record-breaking year — despite, and because of, 2020
With folks housebound by Covid-19 restrictions and more conscious of their home energy needs, April proved a banner month for companies generating digital leads through their own accelerated transition to a new way of working.
Floating solar nearing price parity with land-based US solar
Four years ago, there were just two floating solar arrays in the United States. But by the end of this year, there will be more than 20.
Improving outdoor I-V curve measurements with PV module irradiance sensors
Japanese scientists have replaced common pyranometers with PV module irradiance sensors to measure the I-V curves of crystalline silicon PV modules. The sensors provide highly precise outdoor measurements, the researchers said.
South African platinum mine tenders for 10 MW of solar
Developers have until October 20 to submit bids with the Marula Platinum Mine having lost patience with unreliable power supply from the troubled state electric utility.
India tenders for Himalayan off-grid solar and storage
The Solar Energy Corporation of India has issued a call for expressions of interest to supply clean energy to isolated off-grid communities and warned components will probably have to be transported manually.
Soltec plans IPO
The Spanish solar tracker maker is hoping to debut on the stock markets of Madrid, Barcelona, Bilbao and Valencia this year.
Concentrating photovoltaic-thermal system with 91% efficiency
A global research team has developed a parabolic trough linear concentrating photovoltaic-thermal system to produce heat and electricity, for both residential and large-scale applications. The PV unit relies on Azure Space’s multi-junction solar cells, based on indium gallium phosphide (InGaP), gallium arsenide (GaAs) and germanium (Ge).
kWh Analytics unveils tool to address optimistic pricing, underperformance in PV projects
Jigar Shah, the president of Generate Capital, says that accuracy will come with the use of “objective market data.”
