Graphite’s pivotal role in electric-vehicle battery technology is coming under increasing scrutiny. Graphite is almost exclusively produced in China, and while the processing of the mineral poses serious environmental issues, the alternatives appear costly. Ian Morse looks at what’s next for critical graphite supplies.

This year will be a key period in the development of China’s solar PV market. It is the first year of the 14th five-year plan, the first calendar year after President Xi Jinping announced the 2030-60 carbon emissions commitment, and the first year for utility and commercial unsubsidised projects. IHS Markit expects the solar industry in China to reach another milestone with more than 60 GW of installations this year, advancing the ground for the energy transition and the displacement of traditional energy sources to fullfill the goal of a net carbon future over the next four decades to come.

Professor John Quiggin from the School of Economics at the University of Queensland on where the federal budget falls down.

A well-designed rooftop solar system should last 20 or 30 years, or longer. This guide for choosing the right contractor should help ease your concerns.

Based on current market prices, the five-year contract could be worth almost $4 billion to the $1 billion company, but the TOPCon manufacturer has not publicised the price at which it will supply and install modules for its state-owned sponsor.

IHS Markit has released its latest Global Renewables Markets Attractiveness Rankings, based on measures related to investment confidence and ease of development, with Australia ranking in the top ten.

The federal government will provide $131 million of soft loans for a $177 million, 100 MW solar park near the Jamuna river in Bangladesh’s Jamalpur district, where a second park of a similar size is being planned by Dhaka and a Chinese partner.

Scientists in China took a closer look at the role of defects in limiting the performance of perovskite solar cells, demonstrating a screening effect that could be tuned to make material defects “invisible” to charge carriers, greatly improving cell performance. Using this approach they demonstrate a 22% efficient inverted perovskite solar cell, and theorise several new pathways to even higher performance.

Scientists investigating the aging mechanisms affecting today’s lithium-ion batteries observed that the loss of lithium over time is one of the main causes of performance loss. With this in mind, they developed and tested a “relithiation” process that promises to eliminate much of the cost and complexity from recycling battery components and materials.

First Solar and Nel Hydrogen Electrolyser AS have announced they will collaborate to develop power plant control and other supervisory systems as part of a broader plan to build integrated photovoltaic-hydrogen power plants.
