Technology and R&D

An international research team in China has used Czochralski n-type c-Si wafers from China-based Sichuan Yongxiang to build textured wafers with a thickness ranging from 65 μm to 55 μm. They have used the wafers in heterojunction solar cells ton hit efficiencies close to those of devices cells based on conventional wafers.

GemLife, which describes itself as “luxury resort living for the over-50s,” has set up its own Virtual Power Plant (VPP), and is set to invest $75 million in coming years to rollout the VPPs across more than 10,000 homes in its property portfolio on Australia’s east coast.

Queensland flow battery company, Redflow, has commissioned a 30 kWh zinc-bromine flow battery for the Brisbane City Council.

Australia’s national science agency will seek to the address some of the challenges associated with storing and transporting hydrogen by developing an off-grid, portable hydrogen generator designed to recover the zero-emissions fuel from a liquid carrier at the point of consumption.

Prolux Solutions has developed a redox flow battery with a charging and discharging capacity of 4 kW and 5 kW of peak power. It is designed to be coupled with PV systems in homes with high consumption profiles.

The annual SiliconPV Conference came to TU Delft in the Netherlands in April, and offered an important health check for the science and technology behind solar energy. pv magazine was on site to hear the latest from researchers reaching for higher efficiency through tandem cells and other innovations; looking to understand and mitigate cell degradation mechanisms; and working to cut down solar technology’s consumption of rare and expensive materials.

The new series comes in seven versions, with power outputs between 560 W and 590 W. The power conversion efficiency ranges between 21.7% and 22.8%

US space agency NASA has discovered that perovskite solar cells tested in space exhibit less degradation than reference devices tested on Earth. The agency acknowledged that it is uncertain about the specific factors in the space environment that contributed to the superior performance of the perovskite absorber film.

The ACT government has awarded over a million dollars to support the commercialisation of technologies from six upcoming renewable companies. Round three of the territory’s $12 million innovation fund includes support for a startup which has developed a 3D printer capable of printing electronics.

GoodWe plans to bring a range of building integrated photovoltaics (BIPV) products to Australia, announcing a partnership with specialist Umax Energy. The manufacturer this month released the details of its lightweight new panel, and plans to introduce an integrated solar roof tile to the Australian market.
