Manufacturing

A gigafactory, as the name indicates, is a facility that aims to produce Li-ion cells at a gigawatt-hours scale of total capacity, so they can then be used in electric vehicles or stationary storage applications. The global production capacity of Li-ion cells is expected to reach 740 GWh by the end of 2021 – almost a threefold increase from 2017 – and Europe will account for 8% of the total. João Coelho, an analyst at Delta-EE, looks at how Europe plans to catch up.

The latest global PV industry outlook published by trade group SolarPower Europe, has indicated tight supply of the solar panel raw material is expected to persist this year but the trade body said it would be unlikely to drive further price rises.

Western Australian company Australian Vanadium Limited has been awarded $3.69 million in federal government funding to fast-track manufacturing of large-scale vanadium redox flow battery systems that can be used to support rooftop solar PV or in off-grid settings such as mining, agriculture and remote communities.

The manufacturer plans to start production of the performance-enhanced solar modules in August. The first customers should then receive the products in October.

Australia’s first lithium-ion battery manufacturer, Energy Renaissance, has received a half million dollar grant to develop its pilot manufacturing facility in the state’s Hunter region.

Kent Kernahan has set out to take the heat out of solar cells. He and his partners may end up bringing solar manufacturing jobs to disadvantaged communities, while making low-cost rooftop solar more widely available.

Singapore-headquartered solar manufacturer Maxeon has added another module to its AC range with the unveiling of the new Performance 3 AC panel.

Scientists demonstrated a perovskite-silicon tandem cell that reached 27% conversion efficiency. Though higher tandem cell efficiencies have been achieved, this represents a big jump in efficiency for those utilising n-i-p architecture, which previously had not surpassed 22%.

An international team of scientists developed a technique to isolate individual sources of electrical ‘noise’ within a solar cell. Comparing the technique to being able to pick out a single voice within a 200-person choir, they say the technique will help to improve understanding of where efficiency losses occur within a cell, and effective ways to mitigate them.

Saudi scientists have tested several cooling technologies for solar panels and have found that active techniques work better than passive ones under harsh climatic conditions. The most effective one consists of a system based on four heat pipes immersed in a box of liquid, as liquid bulk, integrated with the back of the solar panel.
