Modules & Upstream Manufacturing

Sunday read: Bringing costs down to earth

Rising efficiencies and the plummeting cost of solar modules over the past few years, recent months notwithstanding, are leading innovators toward ideas that may look unusual in the current tracker-dominated world of large-scale solar parks. Advocates of the new approaches argue that they leave traditional models looking decidedly flat by comparison.

Semi-transparent organic solar cell for window applications

Developed by U.S. scientists, the 10%-efficient device is intended for applications in solar windows and promises efficiencies close to 15%. According to its creators, the cell retained 80% of its efficiency after 1,900 hours at 55 degrees Celsius.

Price increases hit US solar

Price increases, supply chain disruptions, and a series of trade risks are threatening the U.S.’s ability to decarbonise the grid, warned SEIA president and CEO Abigail Ross Hopper.

Hydrogen fuel-cell trucks to be used in zinc giant’s Queensland operations from 2022

Global hydrogen vehicle maker Hyzon Motors Inc. has confirmed five of its ultra-heavy-duty hydrogen trucks will be used by Korea Zinc’s subsidiary Ark Energy in its Queensland operations from as early as next year.

Cylindrical solar panel for street lighting

Developed by an Italian manufacturer, the panel is available in three versions with a power output of 100, 120, and 240 W and has a weight of 5 kg. It is encapsulated in thermoformable plastic technical polymers and can be connected in series with other modules around the same post.

Hanwha Q Cells unveils plan to produce perovskite, TOPCon solar modules

The US$1.28 billion (AU$1.7 billion) plan includes a 3.1 GW production capacity expansion in South Korea, where the company’s solar module capacity will reach 7.6 GW by 2025.

New mounting system for rooftop PV, from Austria

The mounting structure relies on a 5.8m long support rail that does not lie on the roof but is connected directly to a purlin placed below with self-drilling support screws.

Sunday read: looming impacts of international trade disputes on polysilicon

Polysilicon capacity is unable to catch up with rapid capacity expansion in the mid and downstream segments, writes Corrine Lin, chief analyst for PV InfoLink. New polysilicon capacity requires big capex investment and a lead time of more than two years to complete construction and reach full operation. With unbalanced capacity between the upstream and downstream segments, polysilicon prices have been rising since the second half of 2020, with prices for mono-grade polysilicon surpassing CNY 200/kg (US$27.40) in June 2021, up more than 250% year on year.
