Technology and R&D

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.

Australian battery technology startup Relectrify has been given the tick of approval by the International Electrotechnical Commission for its ReVolve energy storage product, opening the way for the company to scale up the global rollout of its cell-level control technology.

Iberdrola is using a springer spaniel in a solar park to smell electrical problems that could lead to power cuts. It is also using a robotic dog to detect and analyse faults in substations.

Australian materials technology developer Kinaltek has unveiled a one-step production process that it says can convert common silica powders into battery-grade nanosilicon for less than 5% of the cost of existing technologies, paving the way for the use of silicon nanoparticles in high-performance lithium-ion batteries.

Clean Energy Associates (CEA) has calculated the price premium that solar developers will swallow in return for the levelised cost of energy (LCOE) savings offered by the latest generation of high-efficiency PV panels.

Canada-headquartered Solmax will seek to build its presence in the Australian utility scale solar sector having developed a reflective membrane which it claims can increase the energy yield of a bifacial PV project by between 5% and 20%, depending on the plant configuration.
