Fully renewable energy feasible for Samoa

Credit: CC0 Public Domain The future of Samoa’s electricity system could go green, a University of Otago study has shown. Pacific Island nations are particularly susceptible to climate change and face high costs and energy security issues from imported fossil fuels. For these reasons many Pacific Island nations have developed ambitious 100 per cent renewable … Read more

Microstructure morphology fine-tuning of active layer film boosts organic solar cell efficiency

Graphical abstract. Credit: Joule (2021). DOI: 10.1016/j.joule.2021.06.017 The power conversion efficiency (PCE) of organic solar cells (OSCs) are demonstrated to be improved via the microstructure morphology fine-tuning of active layer films. Thanks to the appealing advantages like light weight, mechanical flexibility and roll-to-roll processability, OSCs have drawn increasing attention. As a promising power source for … Read more

‘Gallium doping’ is providing a solution

Credit: Shutterstock Solar power is already the cheapest form of electricity generation, and its cost will continue to fall as more improvements emerge in the technology and its global production. Now, new research is exploring what could be another major turning point in solar cell manufacturing. In Australia, more than two million rooftops have solar … Read more

Japan ups 2030 renewables goal in draft energy policy

The world’s third largest economy is still heavily reliant on fossil fuels. Japan aims to hike its 2030 renewable energy target as part of efforts to slash emissions, according to draft documents released Wednesday, but activists described the planned goal as “disappointing”. The blueprint of the nation’s energy policy sets a higher target of 36-38 … Read more

Better batteries for grid-scale energy storage

Postdoctoral researcher Martha Gross works in an argon glove box with a test battery cell illustrating a lab-scale sodium iodide battery. The Sandia National Laboratories research team developed a new sodium iodide catholyte solution (purple liquid) and a special ceramic separator to allow the molten sodium battery to operate at 230 degrees Fahrenheit (110 degrees … Read more
