Scientists in India have proposed to design new tandem solar cells using transition metal dichalcogenide as an absorber material for the bottom PV device. Their simulations showed these tandem cells may reach an efficiency of more than 35%.

Deye has developed a new power conversion system optimised for solar integration, with modules ranging from 100 kW to 125 kW. The Chinese manufacturer says the PCS supports flexible system design and targets commercial and industrial applications.

Indonesia has the resources to quickly increase the share of renewables in its power mix, including abundant solar, geothermal and pumped storage potential to help stabilize the grid. The government has introduced policies to attract foreign investment, including through the Just Energy Transition Partnership, but it is still sending mixed signals about phasing out coal in favor of renewables.

Thai energy company Banpu has snapped up a 50% stake in the 350 MW / 1,400 MWh Wooreen battery energy storage system being built in Victoria’s Latrobe Valley as the Bangkok-based coal producer ramps up investments in renewable energy.

China-headquartered battery giant Contemporary Amperex Technology (CATL), together with a subsidiary and partners have officially broken ground on a vertically integrated battery manufacturing and recycling facility in Indonesia.

Risen Energy says it has achieved an average power output of 740 W for its mass-produced heterojunction solar module, with certified cell efficiency of 26.61% and module efficiency of 24.81%, according to China’s Fujian Metrology Institute. Encapsulation losses were limited to 1.8%.

Malaysian infrastructure giant Gamuda is taking the next step in its Australian growth plans, partnering with landowners in central Tasmania to co-develop a 1.2 GW portfolio of large-scale renewable energy generation and storage projects.

The Chinese manufacturer said the result was confirmed by TÜV Rheinland. It was achieved through a sunken pyramid structure that reportedly achieves selective-texture on the non-electrode area of rear-side and a zebra-crossing passivation contact structure that is said to ensure excellent passivation.

The tandem device is based on a bottom organic cell that can achieve a power conversion efficiency of 17.9% and a high short-circuit current density of 28.60 mA cm2. Furthermore, it uses a top perovskite solar cell with an open-circuit voltage of 1.37 V and a fill factor of 85.5%.

PV module manufacturing capacity in Southeast Asia has reached 86.5 GW across 61 active sites, according to Hong Kong-based quality assurance firm Sinovoltaics. The figures come from the company’s latest “Southeast Asia Solar Supply Chain Map” report.
