Chinese solar manufacturing giant Longi has announced the achievement of a world record 26.81% conversion efficiency from a cell utilising heterojunction technology on full-size silicon wafers in mass production. The company said the measurement has been validated by Germany’s Institute for Solar Energy Research.

Japanese scientists have described the steps that need to be taken to improve the average efficiency of CIGS solar modules, from around 18.5% at present to more than 20%. They presented all of the critical technical factors that are currently holding the tech back from broader market adoption.

Singapore-headquartered infrastructure developer Equis has announced plans to construct a 1,200 MW/2.4 GWh battery in Victoria that it claims will be the largest battery energy storage system yet developed in Australia and Asia.

As Longi and other solar manufacturers kick off massive growth in hydrogen generation capacity, expect large price decreases resulting from steep learning curves, echoing the rapid advances experienced by the solar power industry since the 1970s.

Indian scientists have designed a new all-perovskite tandem solar cell configuration that can reportedly achieve higher efficiencies than similar devices built with the same materials. The top perovskite cell has a wide bandgap of 1.75 eV and the bottom perovskite cell has a bandgap of 1.25 eV.

The Industrial Technology Research Institute (ITRI) and United Renewable Energy (URE) have developed a solar panel that can be easily dismantled to simplify the recycling process. They claim 96% of the materials in the panel can be recovered, including all of the solar cells and front glass.

Australian independent power producer ReNu Energy has signed a deal with the developers of a proposed 3.5 GW solar-plus-storage facility in Indonesia to explore the potential large-scale production of green hydrogen for supply into Southeast Asia and beyond.

Sun Cable is seeking to develop the world’s biggest intercontinental solar and storage project, and has now inked a deal with the Indonesian government that could unlock more than $170 billion (USD 115 billion) in renewable energy generation and transmission operations in the archipelago.

Australia features prominently in the top 10 but the latest edition of Ernst & Young’s renewables attractiveness index rates India as the top market for solar investment while Spain, Germany and the United States are the top three markets for corporate power purchase agreements.

China manufacturer DAH Solar offers four versions of its new panels, with power outputs ranging from 540 W to 555 W and efficiency ratings from 20.89% to 21.48%. The modules are reportedly ideal for steel rooftops with small installation angles.
