A UK-Chinese research group claims to have achieved remarkable efficiency and stability for a solar cell based on an electron transport layer doped with two-dimensional titanium carbide (Ti3C2Tx). The champion cell has an efficiency of 23.66%, an open-circuit voltage of 1.095 V, a short-circuit current of 25.07 mA/cm2, and fill factor of 83.18%.

A recent report by the International Energy Agency Photovoltaic Power Systems Programme (IEA PVSP) reviews the current regulatory and industrial landscape for end-of-life PV management in Germany, France, Italy, Spain, Japan, South Korea, China, Australia, and the United States.

The new energy unit of Reliance Industries has signed an agreement to acquire a 20% stake in California-based perovskite solar startup Caelux for $12 million.

The Indian solar manufacturer has unveiled the 60 5 W Bonito Max panel featuring 156 half-cells and a 10-busbar design. The new product has a power conversion efficiency of up to 21.64%.

The new product is available in four versions with a storage capacity ranging from 9.9 to 19.9 kWh. The battery inverter comes with a 10-year warranty and can reportedly provide steady operation for up to 6,000 charge cycles.

A research group in the Netherlands has analyzed different manufacturing techniques for two-dimensional Ruddlesden–Popper perovskite solar cells. These cells offer improved photostability and environmental stability compared with their three-dimensional counterparts.

The Chinese manufacturer said the modules will have a nominal power of 575 W and a temperature coefficient of -0.32% per C.

The two batteries have a storage capacity of 13 and 19.5 kWh, respectively. Both lithium-ion systems use LiFePO4 as the cathode material and have a round-trip efficiency of over 86%.

The project consists of an 85 MW solar park and a green hydrogen production unit. The facility should begin commercial operations in 2024.

Developed by the French research institute Liten, the prototype kit consists of a 145 W photovoltaic panel, a magnetic rear panel, and an MPPT charge controller. It also includes a battery and a micro-inverter that can be used to inject the stored energy into the grid when the vehicle is recharged.
