The spherical 3D cells can reportedly generate around 101% more power than conventional flat solar cells. Measurements have also shown that the spherical cells provide a 10% lower maximum temperature compared to flat cells, while accumulating less dust.

A German research team has developed a new photovoltaic-electrochemical device for alkaline water electrolysis. The prototype has an initial solar‐to‐hydrogen efficiency of approximately 7.7%.

Scientists in the Netherlands have demonstrated an interdigitated back contact copper-indium-gallium-selenide solar cell with a sub-micron thickness of 673nm. The device has an aluminum oxide and magnesium fluoride-based anti-reflective coating.

European scientists have developed mini modules with an active area of 14 cm² and a 3.68% efficiency rating. The panels also have a self-adjusting feature that can help to mitigate the amount of light when they are exposed to full sunlight, or to the temperatures of buildings with large windows and/or glass facades.

Risen Solar has unveiled plans for a 15 GW cell and module fab in Yiwu City, Zhejiang province and China South Glass is fundraising for a PV glass factory in Anhui province. Such growth, however, may be slowed by the introduction of new standards by the government.

Researchers in Iran have applied the Stackelberg leadership model to determine whether the creation of a closed-loop solar module supply chain – including panel refurbishing – is feasible. According to their findings, a similar supply chain may only be set up with public subsidies, which would ensure that costs for R&D, module production, and recycling are distributed between the government and all the chain’s players.

A Silver Institute study says demand for the precious metal for solar manufacturing accounted for 11% of global consumption last year but reduced solar generation capacity up to 2023 will eat into that figure and ‘thrifting’ technological advances will kick in after that point.

The companies aim to jointly develop higher quality and more competitive cells and modules that will in turn ensure the viability of PV power plants.

JinkoSolar has begun construction of a new 16 GW module production base in Yiwu city, Zhejiang province and Eging PV has resumed a 200 MW solar project in Qitai county in the Xinjiang Uygur Autonomous Region, after securing approval from local authorities. The China National Energy Administration has confirmed the nation can add no more than 48.45 GW of solar to the grid this year.

Scientists have developed a hybrid production method combining metal mesh and a metal-oxide layer over a glass substrate which they say brings down production cost by 80% compared to the tin-doped, indium oxide-based technology currently in use.
