All solar cell efficiencies at a glance
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.
Transparent solar panels for agrivoltaics
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.
Trina Solar achieves 23.03% efficiency for 210 mm PERC solar module
The result was confirmed by Germany’s TÜV Rheinland and TÜV Nord.
Using the oceans’ depths to store renewables, compress hydrogen
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.
1366 Technologies merges with Hunt Perovskite Technologies
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%.
New renewables cheaper than legacy coal or gas for almost half the world’s population
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.
New perovskite material for 23.5%-efficient solar cell
Researchers in Japan have found a new way to fabricate one of the most promising perovskite materials for PV application — the α-formamidinium lead iodide known as α-FAPbI3. With a pre-synthesized version of this material, they were able to produce a cell with a power conversion efficiency of 23.5% and a lifespan of more than 2,000 hours.
‘Low-cost renewable hydrogen may already be in reach’
If the three record-busting low solar price tariffs recorded in the Middle East in the past 18 months are to be believed, renewables-powered hydrogen in prime sites in the region could already compete with gas-plus-CCS production, according to IRENA. Has the Gulf discovered the new petrol?
New microinverter from the US
Yotta Energy’s new micro-inverter is claimed to be an ideal solution for commercial rooftop PV systems linked to between 500 kWh and 1 MWh of storage. The device has a peak efficiency of 96.5% and a nominal maximum power point tracking (MPPT) efficiency of 99.5%.
Concrete flywheel storage system for residential PV
A French start-up has developed a concrete flywheel to store solar energy in an innovative way. Currently being tested in France, the storage solution will be initially offered in France’s overseas territories and Africa.
