France’s Sunbooster has developed a technology to cool down solar modules when their ambient temperature exceeds 25 C. The solution features a set of pipes that spread a thin film of water onto the glass surface of the panels in rooftop PV systems and ground-mounted plants. The cooling systems collect the water from rainwater tanks and then recycle, filter and store it again. The company claims the technology can facilitate an annual increase in power generation of between 8% and 12%.

The Asian Development Bank says developing countries in Asia and the Pacific should consider developing their own solar industry supply chains as the Covid-19 pandemic has exposed their over-reliance on China to carry through the energy transition.

Researchers in Brazil have suggested using solar radiation databases and simulator software to scale PV-diesel mini-grid generators. The profiles of PV generation and mini-grid load demand are critical to finding the right balance, according to the academics.

Chinese manufacturer Risen Energy will supply Malaysia’s Tokai Engineering with 20 MW of its new panels, unveiled in December. Risen claims its products can help reduce balance-of-system project costs by 9.6% and the levelized cost of energy by 6%.

Researchers led by Belgian institute imec claim to have achieved the result with a 1cm² flexible thin-film cell intended for building-integrated PV application. The result tops the 24.6% efficiency the consortium announced in September 2018. The cell’s developers are now aiming for 30%.

Australian researchers have compiled data from 173 studies which examined homeowner behavior when buying rooftop PV and identified 333 predictors related to the attitude, knowledge, tendency, awareness, willingness and intent of householders.

The Australian research team which developed the device said the higher efficiency was achieved through a nanowire design which eliminates the interface inside the titanium dioxide band.

Australian researchers have unveiled hydrogenation technology to reduce light and elevated temperature-induced degradation in Czochralski silicon PERC solar cells. The developers say the process can minimize degradation without sacrificing performance in cells and modules.

The Minerals Council South Africa has urged the government to solve the country’s energy crisis by adding more power generation capacity from both distributed and large-scale renewables. Meanwhile, several mining companies operating in South Africa are planning their own big solar parks, including two 200 MW facilities under development by Sibanye-Stillwater and Vedanta.

UK researchers claim to have proved the viability wearable photovoltaic devices as an integral part of regular clothing. A solar-powered fabric textile was created by embedding micro crystalline silicon solar cells within the fibers of a textile through very thin copper wires. The scientists claim that the novel device can maintain its performance even after 15 domestic machine wash cycles, 25 hand wash cycles, and 6000 abrasion cycles.
