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%.

The cell reached 26.0% efficiency and showed open-circuit voltage values of up to 732 mV. It was fabricated with a back junction (BJ) design with a full-area p-n-junction at the back surface.

A new study from the Lappeenranta University of Technology predicts solar may even achieve a 69% share for total primary energy supply by the end of the first half of the century. In terms of price, solar PV is expected to achieve a capex of €246/kW-installed (AU$385/kW-installed) for utility scale projects, and of €537/kW (AU$840/kW) for residential arrays by 2050. The levelised cost of energy (LCOE), however, is expected to remain constant over the next three decades, as the energy transition will also be implemented with storage technologies, increased flexibility and the production of synthetic fuels.

U.S. company Group 14 Technologies has announced it will launch factory capable of producing 120 tons per year of its innovative silicon-carbon-based anode material for lithium-ion batteries. The factory is located at Group 14’s headquarters in Washington and is the first of several planned by the company.

Greater dispatchability will be required from solar as it becomes increasingly mainstream worldwide, or investors could experience diminishing returns as a victim of the technology’s success at bearing down on electricity prices.

A human hair derivative has been found to protect, stabilise and enhance the performance of perovskite solar cells.

A homegrown technology developed by the University of Newcastle and Southern Green Gas has seen the development of a novel green hydrogen fuel and carbon neutral green methane. The fuel was demonstrated in Hyundai’s Nexo hydrogen fuel cell SUV in Sydney.

Sinopec wants to build 1,000 hydrogen refueling stations by 2025. Ways2H is building a facility in the Tokyo area that will convert daily 1 ton of dried sewage sludge into 40-50 kilograms of hydrogen for fuel cell mobility and power generation. Ørsted wants to deploy two renewable hydrogen production facilities for a total of 1 GW by 2030. Wacker Chemie is planning to produce green hydrogen and renewable methanol at its German site.

Some of Australia’s most thrilling thinkers are scientifically investigating the applications of light and developing new light-absorbing materials. Like human investment in space travel the dedication to solar research is paying back beyond its remit. pv magazine talks to one far-reaching centre of excellence in the field.

Having picked up GBP 5.8 million ($8 million) in a series of investments, U.K.-based Power Roll is pushing ahead with pilot production of an innovative new thin film with which it can manufacture both solar modules and capacitors. In the future, the design could also bring the potential for solar generation and energy storage within a single lightweight device.
