Modules & Upstream Manufacturing

Perovskite developer Oxford PV has set a new world record for perovskite-silicon tandem cell efficiency at 29.52%, edging out the previous record set less than a year ago by Helmholtz Zentrum Berlin. The new record has been certified by the U.S. National Renewable Energy Laboratory.

The Chinese leader has revealed some details of his nation’s commitment to go carbon neutral by 2060. That solar and wind power promise could even prove to be a conservative estimate, according to the nation’s solar industry.

For the first time in years, the Australian Centre for Advanced Photovoltaics (APAC) has received a major grant. The Australian Renewable Energy Agency has funded APAC to the tune of $19 million with the goal of reasserting Australia’s place at the forefront of solar technology and accelerating the competitiveness of renewable energy.

Guarantees and warranties may be thought to deliver peace of mind, but when underperformance on rooftop systems is detected, diagnosing and demonstrating failures is no simple task. pv magazine’s Virtual Insight on Quality event in November tackled this issue from all angles – and what it means for Australia’s burgeoning rooftop segment.

With PV manufacturer warranties being extended and new novel designs coming on to the market at greater frequency, the quality assurance practices standing behind claims are becoming increasingly important. A new program from TÜV Rheinland is looking to provide the assurance that installers, distributors and project developers need – particularly in the hot and humid environments proven to push the boundaries of module durability.

The pandemic and accidents at polysilicon labs in China’s Xinjiang region put PV manufacturers under pressure to maintain production this year, while slowing cell and module R&D. After half-cut and multi-busbar becomes commonplace, manufacturers will continue to explore the high-density assembly methods that emerged last year, as well as n-type cells. But the market is also shifting to large formats, and the share of bifacial products is growing this year. As sizing up modules can bring immediate returns, PV InfoLink’s Amy Fang expects the PV industry to prioritise the development of large formats and bifacial products next year.

The multi-functionality of building-integrated PV (BIPV) shapes as a key driver to increased PV penetration in the Australian energy market as rooftop installations continue to dominate.

German standards body TÜV Rheinland is introducing a new testing and certification program for pv modules. The program incorporates component specific tests and ongoing, random testing of running production lines. Hanwha Q Cells assisted in the development of the program, and this week announced it is the first manufacturer to receive the new Quality Control PV Certification.

Scientists in the Netherlands are planning to build intelligent PV devices for energy and information applications. Their intention is to make this approach a new field of PV research, whose ultimate goal is enabling solar cells to communicate with each other and with other devices, ensuring that all the generated energy ends up exactly where it’s needed, especially in the urban environment.

The Australian arm of South Korean solar technology giant Hanwha Q-Cells has applauded the decision by the Chinese Patent Office to uphold the validity of the company’s intellectual property rights on key technology.
