Modules & Upstream Manufacturing

Chinese giant Huawei has entered Australia’s residential solar battery market with its home energy storage system, the Luna2000. The lithium-iron phosphate 5kWh cells have a modular design and are scalable to 30kWh. Huawei is banking on 10 kWh system capacities being most popular, telling pv magazine Australia they will retail for under AU$10,000.

Cross-pollination of scientific and engineering thought within the ARC Centre of Excellence for Exciton Science has led to promising findings on the the cool solar-cell efficiency-boosting mechanism known as singlet fission.

It’s claimed the decentralised desalination system can deliver a levelised cost for desalinated water of US$0.7-4.3/m3, depending on PV costs and electricity prices. It was built with several concentrated photovoltaic/thermal (CPV-T) collectors, a hot water tank, a V-MEMD module, a seawater feed tank, and a distillate tank.

Queensland flow battery company, Redflow, has unveiled the product it’s hoping will launch its lucrative high-voltage, high-capacity, grid-scale future: the Energy Pod Z module.

Researchers in the United Kingdom have built a 14%-efficient organic PV device that can be used in high-speed optical wireless communication systems. The cell consists of a 4×2.5mm photoactive layer fabricated with a bulk heterojunction of a polymer donor and fullerene and non-fullerene acceptors.

Scientists in China have analysed the radiative cooling techniques used in combination with solar energy systems such as PV arrays, solar thermal collectors, and concentrated PV installations. They identified five major system typologies based on functionality and working time.

There has been a flurry of activity within the PV cell manufacturer landscape over the past 12 to 18 months, and it’s largely been in one direction: bigger. But as large-format modules arrive on the market, questions are being raised as to how long the trend can continue and when bigger becomes, quite simply, too big.

Australia’s only solar module manufacturer Tindo Solar has unveiled a new generation 400 W module for the domestic and export markets as the Adelaide-based company rides a wave of success that has delivered a 40% increase in retail orders and 70% rise in wholesale orders in the past 12 months.

The 1 GWh first phase of a planned 8 GWh lithium battery factory in Thailand is likely to be up and running during 2023.

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.
