Modules & Upstream Manufacturing

Australian solar industry remarkably silent as global pressure mounts around allegations of forced labour in supply chain

The solar industry in Europe and the United States is continuing to ramp up the pressure on the use of polysilicon produced in Xinjiang, China – in response to allegations that forced labour is being used in its production. By contrast, the Australian industry’s response has been markedly muted. Although it is true that most global solar industries are heavily reliant on Chinese manufacturing, Australia is overwhelmingly so.

German researchers overcome main challenge for perovskite PV modules

Researchers in Germany claim to have overcome the primary hurdle in the development of large-area perovskite PV modules – scaling up from the cell to the module level. They achieved an efficiency of up to 16.6% on a module surface of ​​more than 50 centimetres squared, and 18% on a module with an area of 4 centimetres squared.

Longi unveils two PV modules for distributed generation

The two new products will be part of the Hi-MO4m panel series for rooftop applications. Their efficiency ranges from 19.2% to 21.2%.

UNSW’s Prof Martin Green ups PV yield by cooling solar modules

In efforts to improve PV performance by helping modules keep their cool, the Martin Green team is going for 10 degrees lower operating temperatures. Cherry-picking the most practical approaches could deliver 50% extended project life.

Sunday read: time to standardise

Not all quality control plans, processes and agreements are created equal, writes Frédéric Dross, the VP of strategic development for Senergy Technical Services (STS). Indeed, developers can find themselves saddled with agreements that allow unacceptably low levels of quality, unless they have followed standards.

Saturday read: the more you know

Module-level power electronics, most often in the form of power optimisers and microinverters, offer a range of value propositions, including advanced monitoring capabilities. But how much can the little box behind the module really see, and how much do operators actually need to know to keep a power plant running optimally?

Solliance hits record efficiency on perovskite/silicon tandem solar cell

The Dutch consortium has achieved the record result by combining, in a four-terminal tandem configuration, an 18.6% efficient highly near-infrared transparent perovskite with a prototype of a c-Si interdigitated back contact (IBC) silicon heteroJunction (SHJ) cell developed by Japanese electronics manufacturer Panasonic. The perovskite cell was also combined with other kinds of solar cells and other remarkable record efficiencies were hit.

Renascor finalises $15m capital raise, on track to be world’s first battery-grade graphite producer outside of China 

South Australian company Renascor Resources this morning confirmed it had raised $15 million from institutional investors in Australia and abroad, enough to fund its Siviour Battery Anode Material Project up to the construction phase. The project is on track to become the world’s first integrated mine and purified spherical graphite operation outside of China.

First Solar claims lowest module degradation rate in the industry

The US cadmium telluride thin-film module maker said its Series 6 CuRe panels are able to retain 92% of its performance at the end of the 30-year warranty. The improved stability of the product was achieved by eliminating copper and placing Group V elements such as antimony or arsenic onto the tellurium crystal sites.

Space PV technology company acquired to ‘unlock notable market potential’

The company being acquired, Azur Space, produces triple-junction space solar cells with an average efficiency of up to 30% and is planning to develop ultra-thin solar cells with up to 35%.
