South Korean scientists have transformed an opaque crystalline silicon solar cell into a transparent one by punching holes into it measuring around 100 μm in diameter. A neutral-colored, transparent c-Si substrate was used to develop the new cell, which is said to have an efficiency of up to 12.2%.

Japanese utility Kansai Electric Power has extended a demonstration project with Australian P2P energy pioneer Power Ledger to track renewable energy certificates and trade PV-generated electricity.

According to a new study by Finland’s LUT University, solar PV consumes between 2% and 15% of the water that coal and nuclear power plants use to produce just 1 MWh of output; for wind, this percentage ranges from 0.1% to 14%. Under the researchers’ best policy scenario, water consumption could be reduced by 75.1% by 2030, compared to 2015 levels.

The 8.5 kW pilot project, which was launched in February 2018, will soon be expanded to 50 kW. The Dutch consortium behind the installation eventually plans to expand it to 1 MW and then up to 100 MW at a later stage. The Netherlands Enterprise Agency (RVO) provided financial backing for the project.

The Australian state of Tasmania has approached international investors to present its unique potential for the production of hydrogen from renewable sources, as it aims to position itself at the forefront of the nation’s green hydrogen push.

Eleven U.S. Senators have signed a letter to the Federal Energy Regulatory Commission about the threat that Huawei’s equipment poses to the nation’s energy infrastructure.

The Australian Renewable Energy Agency has announced AUD 15 million ($10.3 million) in research funding to investigate end-of-life issues for PV modules. Ultimately it is hoped that the research will increase solar PV efficiency while lowering costs.

NREL has published a paper showing an experimental solar cell, with a unique technique for wiring two separate solar cells into one, that increased the cell’s efficiency by 4%. The document also offers a respectable review of other technologies being developed.

An international research team has developed a new approach for solar power forecasting that combines neural networks and pattern sequences for the first time. The performance of the new Pattern Sequence Neural Network (PSNN) was tested on an Australian data set that includes information from two years of forecasts. It can be used with different clustering and cluster-sequence extraction algorithms, and can be applied to multiple related time sequences

Scientists from Israel have used nanowires to detach particles from the surfaces of solar panels. The proposed microscopic self-cleaning technology is said to raise the efficiency of particle removal with hydrophobicity.
