Technology and R&D

SMA Australia had a bumper year in 2020, despite increasing competition and Covid-19, and partly because of the West Murray crisis. What’s next?

A collaboration between the U.S. National Renewable Energy Laboratory and the UNSW has yielded a new efficiency record of 32.9% for a tandem cell device utilizing III-V materials. Key to the achievement was a new technique enabling the researchers to take advantage of “quantum wells” in the material that serve to trap charges and enable tuning of the cell bandgap to absorb more of the light spectrum.

Soon 2020 will only be a worry to future high-school history students. But when they ask us if anything good at all happened in 2020, remember this review and tell them that solar PV shone in the darkness. Despite the mess of it all, 2020 has been another good year for Australian solar. The industry has demonstrated resilience, and significant progress has been made in the fields of energy storage, green hydrogen and others.

Powertracer is a new Australian-developed data platform that accounts for the origins of each retail customer’s energy in half-hour blocks. The effect is to open up new models of choosing and offering renewably sourced energy, and accelerate demand.

Australian scientists have demonstrated two loss-mitigation techniques that could improve solar‐to‐hydrogen (STH) conversion efficiencies and may lay the ground for cheaper PV-powered hydrogen generation. By combining the two techniques, they were able to achieve an STH efficiency of around 19.4% at realistic operating temperatures.

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.

Hydrogen demand in South Korea is expected to reach 17 million tonnes by 2050. An ambitious solar PV project in the heart of Queensland’s unconventional-gas country, plans to be an early green supplier of the manufacturing nation’s hydrogen needs.

Victorian Minister for Energy, Environment and Climate Change, Lily D’Ambrosio, has announced accelerated targets for the Victorian Energy Upgrades program, a way for Victorians to save on their bills and contribute to the state’s emissions reduction targets.

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.

A collection of mining companies, industry bodies and union groups have been announced as the members of the Future Battery Industry taskforce, the Western Australian McGowan Government’s unit designed to grow the value chain of critical minerals for the energy storage industry for domestic use and export opportunities.
