pv magazine rounds up the latest Covid-19-related stories likely to affect the world of solar and energy storage.

Scientists in Germany have developed a “heavy duty” test to provide insight into the long term effects of potential induced degradation in PV modules. The tests go well beyond those established by IEC standards and seek to guide manufacturers and investors on the best choice of materials – encapsulants in particular – when it comes to long term PID resistance.

An Italian consortium has developed a panel recycling process it claims can recover up to 99% of raw materials. The developers claim their technique takes only 40 seconds to fully recycle a standard panel, depending on size and recycling site conditions.

French agricultural PV specialist Sun’Agri has revealed the results of tests run on a solar plant integrated with viticulture. During heat waves, the company said, vines shaded by solar panels continued to grow and needed less water.

Scientists in the U.S. and South Korea have identified what could be a new route to high-efficiency perovskite-silicon tandem solar cells. Through engineering negatively charged particles in the passivation layer, the group made a tandem cell with 26.7% efficiency. With further tweaks to the silicon layer they expect to be able to surpass 30%.

During an online launch event, a Blade Battery pack was pierced with a nail without becoming unstable or experiencing dangerous high temperatures. The company says the device will be safer during car accidents.

The Middle Eastern kingdom has ordered the shutdown of solar wheeling facilities which use the grid to connect to energy offtakers. The move has come in response to tumbling electricity demand after the nation halted all non-essential industries as it tries to limit the spread of Covid-19.

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%.

Another big solar event has joined the list of those canceled because of Covid-19. The next edition of The Smarter E event will take place next year.

French energy giant Total and German start-up Next2Sun have joined forces to develop vertical PV solutions in the French market. The oil group’s unit Total Quadran plans to use the solution in agrivoltaic projects.
