Terbium-doped perovskite solar cell with 17.5% efficiency
An international group of scientists has used bulk passivation and surface passivation techniques to implement terbium doping in an all-inorganic perovskite solar cell, while using quantum dots to improve the stability of the perovskite itself.
Sharp presents 375 W rooftop PV module for gable roofs
Sharp’s new 375 W solar panels feature multi-wire technology, with a power conversion efficiency of 20.4%.
Wacker to expand silicon metal production in Norway
Polysilicon manufacturer Wacker has launched a feasibility study for its expansion plans in Norway. It said its production capacity in the village of Holla could increase by 50% by 2025.
Indian developers switch on 300 MW of large-scale solar
Tata Power has commissioned a 100 MW solar project in the Indian state of Maharashtra, while Acme Solar has turned on a 200 MW PV facility in Rajasthan.
Q Cells confirms location of next US solar panel factory
South Korea-based Q Cells will invest $171 million in a new factory in Dalton, Georgia, creating nearly 500 new jobs.
Irish authorities approve subsea power link to France
Ireland has given the green light to install a 700 MW, high-voltage direct current submarine power cable between its southern coast and the northwestern coast of France.
Multifaceted ferrocene interlayer for 23.45%-efficient perovskite solar cell
The cell stability was improved with the addition of ferrocene at the perovskite/spiro-OMeTAD interface. It was able to retain around 70% of its initial efficiency after 1,250 hours.
Open-source software to identify best locations for PV projects in urban areas
The proposed methodology relies on geographic information and meteorological data. Project developers can use it to evaluate the potential energy production by a photovoltaic system for either a long or short time.
Risen launches 450 W rooftop solar module with 21.7% efficiency
The panel measures 1,894 mm x 1,096 mm x 30 mm, weighs in at 22.5 kg, and has a temperature coefficient of -0.34% per C.
Cutting out cadmium for a 16.7%-efficient flexible thin-film solar cell
Scientists in Japan have developed new processes for CIGS solar cell manufacturing, entirely eliminating the use of cadmium and replacing a waste-intensive wet chemical stage. With a thin film deposited on a flexible steel substrate, the group achieved 16.7% efficiency, which it says is a record for a cell of this type produced using scalable fabrication processes.
