World

Despite much of the world being on lockdown for a big chunk of 2020, there are few who could say it has been an uneventful year. And while the ongoing Covid-19 pandemic will be what defines 2020 for many, in the solar industry there’s plenty more to shout about, from the rapid rollout of high-powered modules to a drastic increase in carbon-neutral pledges from companies and governments around the world. Across five installments, pv magazine takes a look back at the year in solar. First up are the U.S. election and carbon neutral pledges.

Many solar companies’ stocks have soared this year, and a number of companies have seen their share prices quadruple over the past 12 months.

A new EU framework designed to incentivize cross-border renewables financing could help accelerate the roll-out of solar PV projects across Europe. However, investors are awaiting more clarity about how the system will work in practice.

Market observer IHS Markit has shared its forecast installation figures for 2021, where they expect a ‘wild ride’ for the PV industry to install 158 GW of new generation capacity. This figure amounts to 34% growth on 2020 installations, driven by completion of delayed projects from this year, as well as a generally increased appetite for PV and renewables around the world.

The world is still combating Covid-19, with Europe now impacted by a second wave of the virus. While the market reported delays for a few projects, the impacts on the PV sector remain unclear. But if the world fails to curb the Covid-19’s spread, governments may be forced to reintroduce strict measures, thereby sapping PV demand. PV InfoLink’s Mars Chang expects module demand to hit 126 GW by the end of this year.

Last week, the European Commission announced it plans to implement sustainability standards for Europe’s growing battery industry. Consultant Circular Energy Storage published a report on lithium-ion battery life cycle and recycling economics this month and its findings ask tough questions of the commission’s proposals.

A new paper from scientists at Germany’s Fraunhofer Institute for Solar Energy Systems (ISE) examines the entire history of PERC technology, from its beginnings in laboratories more than 40 years ago to today, where it represents the majority of all PV cell production. And this story is far from over, as ISE lays out a pathway to efficiencies of 26% as well as use as the bottom cell in a tandem device that it believes will keep PERC technology in mass production to 2030 and beyond.

The Helmholtz Zentrum Berlin set a world record for perovskite-silicon tandem cell efficiency last year at 29.15%. The group has delved further into the cell materials, looking to better understand mechanisms behind the impressive efficiencies achieved so far. Their latest work shows that with the current cell design, long term stability at efficiencies up to 32.4% should be possible.

Throughout this year, a fast-moving story has played out in PV module technology, with the introduction of larger wafers and subsequently larger module formats seeing the industry break into two camps, backing either 182 mm or 210 mm wafers. It remains to be seen whether one or the other will become a new industry standard, and both sizes will likely be plentiful on the market for the next few years at least. pv magazine takes a look at how we got to this point.

Unsubsidized solar keeps moving forward in Germany, the US, Egypt, Italy, the Philippines, France and South Africa.
