EnerVenue signed its first major distribution agreement with Hong Kong’s Towngas. The deal will pilot the company’s nickel-hydrogen battery technology and serve as an audition for future deals to come.

The PV plant—to be set up in the state of Gujarat for a private utility—will supply power for INR2.22/kWh for 25 years.

Researchers in Bangladesh have simulated a solar cell based on a copper bismuth oxide material, used as an absorber, with n-type cadmium sulfide (CdS) utilized as a buffer layer. In the experiment, the device achieved an efficiency of 26.0%, an open-circuit voltage of 0.97 V, a short-circuit current density of 31.61 milliampere per square centimeter, and a fill factor of 84.58%.

New research from Singapore has found that gas pipelines for the onshore transport of green hydrogen and the cables for the transport of electricity to produce it at a distant location have similar costs at a 4000 km transmission distance. For longer distances, gas pipelines were found to be cheaper than cables, although the electric lines are said to benefit from scaling up and higher utilization. For both options, however, a currently too high hydrogen LCOE remains the biggest barrier to overcome.

Xinte unveiled a $197 million plan to raise its polysilicon production capacity to 100,000 metric tons per year in Xinjiang. Longi signed a strategic cooperation agreement with oil and gas giant Sinopec to jointly develop hydrogen and renewable energies.

Projects selected in the procurement exercise will sell power to the Solar Energy Corporation of India (SECI) under a 25-year PPA.

The tracker has a length of 72 meters, which the company says allows for 120 modules per tracker. The new product was conceived as a multi-drive, dual-slewing system that is claimed to have improved overall stability compared to other products and to show a reduced aeroelastic effect.

Researchers in Japan have built a PV-powered device to measure volumetric variations in blood circulation. The system, which is just a few microns thick, was built with an organic solar module, a polymer light-emitting diode (PLED), and an organic photodetector.

The proposed technique is said to be able to connect directly to the microscopic and medium scale defects in the solar cell materials. It is based on three kinds of noises that science has thus far been able to identify in PV devices.

Risen will sell 50,000 metric tons of poly to Shangji Automation and Zhonghuan Semiconductor has raised the prices of all its wafer products.
