A study from the Lappeenranta University of Technology states a deeper complementarity between solar and wind generation may favor renewables deployment reducing the need for stronger developments in storage technology. Combining solar with wind more widely could also reduce the need for ramping and improve the reliability of energy supply, say the researchers.

Taiwanese cell manufacturer Inventec Solar reportedly halted production this month and Ireland is preparing to remove rooftop solar panel restrictions, according to the Irish Independent.

Scientists in Australia took a close look at the long-term performance of passivation layers in silicon solar cells, and discovered a surprising process of degradation and regeneration at work within the material. The results could have implications on the processes used in industrial scale solar cell production.

Given the number of batteries (primarily lithium-ion) that are required to decarbonize the power and mobility sectors, the industry is now preparing for a mountain of battery waste. Recycling is technically feasible, but is also subject to sensitive economics. The framework in which recycling companies can achieve the best life-cycle costs for batteries needs to be carefully enabled through policy – and it will likely include a mixture of technologies and business models, in order to allow life-cycle emissions of batteries to be brought down.

Scientists in Canada have discovered a promising technique for the production of gallium-arsenide solar cells. Growing these cells directly onto a silicon substrate is a promising strategy that could cut out some of the technology’s exorbitant production costs. And by making that silicon porous, scientists may have taken a step toward producing high-performance III-V solar cells at a significantly lower cost.

While mono-grade polysilicon prices did not decrease much in the first quarter owing to stable demand, multi-grade fell to record lows as its market share diminished. During the second quarter, writes PV InfoLink senior analyst Cooper Chen, the market saw excessive supply. Monocrystalline manufacturers have been running at full tilt and bringing new capacities online as scheduled, while the pandemic rages on overseas.

A report from Wood Mackenzie predicts lithium-iron-phosphate will overtake lithium-manganese-cobalt-oxide as the dominant stationary energy storage chemistry within the decade.

Negative second-quarter updates from China and uber-low new-solar figures from India, however, show the world is far from out of the woods yet.

Bifacial modules are one of the older developments in solar panel technology, dating back to the 1960s. It is also one of the latest advances to take hold. According to many experts, however, it is now on track as the latest trend to sweep the solar industry and will soon become the standard.
