Spanish researchers have discovered a material said to offer radiative cooling and self-cleaning of devices which undergo critical heating during operation, such as PV panels. The thermal emitter enabled the scientists to lower the daytime temperature of silicon wafers by 14 degrees Celsius.

A U.S. research team has used protein bacteriorhodopsin to improve the efficiency of what it called ‘bioperovskite’ solar cells. The scientists used Förster Resonance Energy Transfer to predict the strength of long-range excitonic transport between the perovskite and protein layers.

The facility will be developed under the World Bank’s Scaling Solar initiative on a public-private partnership basis in Herat province.

A British study has found co-location of solar and storage may accelerate the deployment of profitable merchant renewable energy projects in the United Kingdom. The report predicts installed solar capacity in the U.K. could increase from around 13 GW next year to 19 GW in 2030 and 32 GW in 2040.

Deploying commercial and industrial PV in China without subsidy is already profitable in some areas, according to a new study, but prohibitive soft costs and cheap electricity are the main barriers for such installations in areas where grid parity remains out of reach.

According to the Taiwanese market research company, PV panel demand will increase by 16% over 2018 shipments. TrendForce also believes this growth trend will continue in 2020.

The European solar trade body expects 128 GW of new PV capacity in 2019, with China likely to bring around 43 GW online and Europe experiencing enough demand to deploy about 20.4 GW. In 2020, global solar demand is expected to reach 144 GW, while in the following three years new PV additions are forecast to total 158 GW, 169 GW and 180 GW, respectively.

A research team has applied a waterproof coating obtained from graphite to a perovskite cell intended to power the production of hydrogen underwater. The cell is said to have worked underwater longer than expected.

And the analyst expects that annual new additions figure to rise to 10.6 GW in 2025. This year the U.S. will surpass South Korea as the largest storage market due to new capacity for solar-plus-storage projects. In Japan and Australia, growth will be spurred by the termination of FIT programs.

The Japanese multinational will transfer its Panasonic Energy Malaysia unit to Chinese heterojunction module provider GS-Solar as part of a broader cooperation agreement. Panasonic’s solar R&D business will form part of a JV in Japan to be 90% owned by GS-Solar.
