Modules & Upstream Manufacturing

Dutch EV start-up Lightyear is already producing prototype roofs to extend the range of its Lightyear One solar car. The roofs will feature interdigitated back contact solar cells made by U.S. company SunPower and backsheets from Dutch multinational DSM.

U.S. researchers have created a new model to assess the overlap between solar potential and underlying land use. The areas with the largest potential are the western United States, southern Africa, and the Middle East. The researchers concluded that croplands, grasslands, and wetlands are the top three land classes for PV projects linked to agricultural activities, while barren terrain, traditionally prioritized for solar PV system installation, ranked fifth.

The new JW-HT132N series features six n-type panels and offers 345 W to 370 W of frontside power output, with efficiencies ranging from 18.68% to 20.04%. The panels are manufactured with a transparent backsheet, with black mesh and a black frame.

Researchers at Germany’s Fraunhofer Institute for Integrated Systems and Device Technology IISB are trying to understand the causes of light and elevated temperature induced degradation (LeTID) in PERC solar cells. Initial investigations should provide a comprehensive understanding of the process and material dependency of LeTID and related degradation effects in monocrystalline and multicrystalline PERC solar cells.

Daqo revealed it will list its main production unit in Shanghai, while Goodwe secured approval for its own plans to list shares. Cybrid Technologies, meanwhile, said it will ramp up production of polyolefin elastomer (POE) encapsulant films.

Researchers from the Solar Energy Research Institute of Singapore have concluded that utility-scale PV projects relying on bifacial panels and single-axis trackers deliver the lowest levelized cost of energy in most of the world. They found that the combination of bifacial products with dual-axis trackers is still too expensive, despite the higher yield. The second-lowest LCOE is offered by monofacial single-axis tracker plants.

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.

German equipment manufacturer teamtechnik announced it has received an order from a European module manufacturer for several stringers to process nine busbar half cells. Already a major trend among module makers in China, 9BB technology now looks to be headed further afield.

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 Chinese manufacturer this morning said the International Trade Commission had agreed with the initial determination issued by an administrative law judge in April, that Jinko and peers Longi Solar and REC Group had not infringed Hanwha’s solar cell passivation technology.
