Technology and R&D

Brisbane company Li-S Energy has developed its third-generation semi-solid state lithium sulfur battery cells. The 20-layer cells, produced in its facility in Victoria, are lightweight and energy dense, reaching over 400 Wh/kg.

Sandbox Solar, a solar developer and US federal grant recipient, has released a beta version of its software modelling tool for agrivoltaic power plants. It supports the design and optimisation of solar panels, as well as the crops underneath.

Western Australian battery technology company Altech Batteries has included “game-changing” sodium chloride technology in the design of its new battery 1 MWh GridPack which is expects will be up to 40% cheaper to produce than the dominant lithium-ion alternatives.

A consortium led by the Fraunhofer Institute for Solar Energy Systems (ISE) will test grid-forming inverters at a large-scale PV facility in southern Germany. The aim of the first tests is to examine the performance of the devices under real operating conditions, stress factors, and typical stress profiles.

Australia’s national science agency, the CSIRO, estimates the country could require a 10 to 14-fold increase in its electricity storage capacity between 2025-2050. It has released its energy storage report, forecasting demand in different sectors and summarising storage technologies.

Sunmaxx says Fraunhofer ISE has confirmed the 80% efficiency of its new photovoltaic-thermal (PVT) module. It consists of 108 PERC half-cells in M10 format, with 400 W of electrical output and 1,200 W of thermal output.

Amprius has obtained third-party performance verification for a battery cell that offers high power density in a lightweight package.

The search for ever higher conversion efficiency has driven solar researchers to focus on back-contact cell approaches, and efforts to devise more cost-effective manufacturing are bringing technologies such as interdigitated back contact (IBC) solar into the mainstream, as Mark Hutchins reports.

Access to extremely detailed consumer energy data is becoming available in Australia part of the federal government’s Consumer Data Right scheme. Used imaginatively, the data has the potential to improve how investment decisions are made, and could even open up new approaches to energy retailing, Stuart Low, founder of Biza tells pv magazine Australia.

PV Expo and the wider Smart Energy Week wrapped up in Tokyo last week. It revealed ambitious plans for solar and energy storage installations in Japan, including creative approaches to dealing with a severe lack of space for new installations, which should bring plenty of opportunities for domestic and international players.
