Thin-film

Strong net sales, 1.6 GW of bookings, plans for a 445 W panel, and environmental recognition for the Series 6 line point to another successful quarter.

A scientist familiar with First Solar’s earlier efforts in CIGS makes the case for the CdTe pioneer to return to the technology.

Scientists in the United States theorize that a ‘double absorber’ cell comprising two active thin-film layers within one cell stack could achieve impressive efficiencies, whilst eliminating many of the challenges inherent to the design of tandem cells. For now though, it’s only on paper.

An international research group has found that the presence of a few lattice defects in a kesterite PV cell material can actually improve efficiency, rather than lowering it. The group believes that kesterite PV cells could see mass production within the next decade.

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.

Another stalwart of the solar industry was able to take the necessary precautions in order to maintain a sense of normalcy during the pandemic, leading to a quarter of increased sales, net cash, and a positive outlook to finish off the year.

Scientists in the Netherlands are trialing a floating solar installation based on flexible thin-film PV modules. The idea behind their concept is that such modules, in combination with a newly designed flexible racking system, will create a system able to roll with the movement of the water, rather than attempting to defy it.

pv magazine’s Quality Roundtable this year brought together experts from a broad range of applications relevant in the solar industry. The overarching theme this year was quality concerns with new technologies. Experts from companies and research institutes held that the failures that the industry has observed with technologies such as 2P single-axis trackers are not inherent in the technology but can be addressed.

Researchers in Australia have conducted a ‘cradle to grave’ life cycle assessment (LCA) of the four most widely used PV technologies. The academics say that cadmium telluride solar modules have the lowest life cycle impact, followed by amorphous, multi and monocrystalline silicon products.

German engineering association the VDMA expects a difficult year because of the Covid-19 crisis. Sales had already dropped considerably last year and the current order intake level offers no glimpse of hope. However, the public health crisis may offer business in new markets determined to break a dependence on Chinese panels.
