Saudi scientists have tested several cooling technologies for solar panels and have found that active techniques work better than passive ones under harsh climatic conditions. The most effective one consists of a system based on four heat pipes immersed in a box of liquid, as liquid bulk, integrated with the back of the solar panel.

The PV module relies on Jinko’s TOPCon mono cell technology, for which a record efficiency of 25.25% was announced in late May. TÜV Rheinland has confirmed the result.

There’s talking the talk, there’s walking the walk, and then there’s walking the walk on water. Earlier this year at US President Joe Biden’s Virtual Leaders Summit on Climate, Singaporean Prime Minister Lee Hsien Loong said the city-state would need to “innovate and use technology extensively” to overcome its resource scarcity. With one of the world’s largest floating PV arrays now in operation, it seems as if Singapore is floating in the right direction.

We will need 10.7 TW of clean energy generation capacity this decade to stay on track with the most ambitious of the climate change paths agreed in Paris, which would include plenty of solar investment and jobs, according to the International Renewable Energy Agency.

The research group led by Professor Martin Green has published Version 58 of the Solar cell efficiency tables. He spoke with pv magazine about the criteria with which these tables are compiled and the importance of result certification by independent third parties.

Romande Energie and Swiss research institute Agroscope are testing startup Insolight’s transparent PV panels in an agrivoltaic project. The modules are replacing the plastic covers used to grow strawberries and raspberries.

The result was confirmed by Germany’s TÜV Rheinland and TÜV Nord.

Underwater gravity energy storage has been proposed as an ideal solution for weekly energy storage, by an international group of scientists. The novel technology is considered an alternative to pumped-hydro storage for coasts and islands without mountains that are located close to deep waters, and may also be interesting for PV if used to store green hydrogen.

U.S. thin-film manufacturer First Solar and Bill Gates-owned Breakthrough Energy Ventures (BEV) are among the investors in the new company, which is called CubicPV and is expected to develop multi-junction perovskite solar cells with efficiencies of around 30%.

Electricity bill payers in nations as diverse as China, India, Germany, and Greece should be aware new solar projects can now generate electricity cheaper for them than legacy coal and gas-fired plants.
