Technology and R&D

Researchers from the University of New South Wales (UNSW) predict that growth to 60TW of photovoltaics needed to rapidly reduce emissions to ‘net zero’ and limit global warming to <2 °C could require up to 486 Mt of aluminium by 2050. A key concern for this large aluminium demand is its large global warming potential.

In a recent media brief, new Enel Green Power CEO Salvatore Bernabei said the company’s heterojunction solar module factory in southern Italy will be scaled up from 200MW to 3GW by mid-2024. He also revealed that another factory may be built abroad, with the United States being a possible location.

The Chinese manufacturer has upgraded its commercial application battery with a dissipative balancing technology that, it is claimed, will make the storage system suitable for different load conditions. Each battery module is sold with a capacity ranging from 100 to 200Ah and a storage capacity of 7.68kWh.

Italian and Iranian researchers have developed the new “deposition via an antisolvent-soaked applicator” technique, which they describe as an easily scalable process to produce uniform, pinhole-free perovskite films. They tested the process on a 6.7%-efficient solar cell based on a polyethylene terephthalate substrate, raising its power conversion efficiency by 82%.

Sun Age, an Italian mounting system supplier, has developed a special bracket for rooftop PV installations on sloped tile rooftops. It is made of stainless steel and can be deployed by fixing it to the surface with dowels or glue.

The portable storage system contains lithium batteries, a charger, and an inverter, all fully integrated into a sealed and protective case.

KPS Power Generation has converted a 10 MW diesel-fueled power station at a mine in South Australia into a hybrid PV facility.

The BW-HY3600 and BW-HY4600 inverters can be integrated with existing on-grid or off-grid PV systems and a battery storage system of 48V. Both devices, according to German manufacturer Bosswerk, have AC and DC coupling and are particularly suitable for residential and commercial solar arrays.

Researchers in Switzerland have replaced the electron transport layers in perovskite solar cells with a thin layer of quantum dots. On an area of 0.08cm², they achieved a record efficiency of 25.7% and high operational stability.

Scientists in Singapore have developed a cell that could be used to power vehicles and boats, among other applications. The tandem device purportedly retains 90% initial efficiency after 500 hours of maximum power point tracking under continuous one sun illumination.
