The Hydrogen Stream: India’s Uttar Pradesh receives INR 1.15 lakh crore investment proposals from 17 firms for green hydrogen production
The state government of Uttar Pradesh has received investment proposals amounting to close to INR 1.15 lakh crore from 17 different entities for producing green hydrogen/green ammonia
Using surplus PV power for seasonal underground thermal storage
Scientists have proposed a new system that uses surplus PV energy in the spring and the autumn to charge up underground thermal energy storage for later use in the summer and winter. They have simulated it on a school facility in Seoul, with a few optional configurations for thermal storage. Power savings were up to 39%.
Longi achieves 34.6% efficiency for two-terminal tandem perovskite solar cell prototype
In a paper published in nature, the Chinese module maker explained that the 33.9%-efficient tandem device it unveiled in December 2023 is based on a bilayer intertwined passivation strategy that combines efficient electron extraction with further suppression of nonradiative recombination. It also revealed that its two-terminal tandem prototype devices achieved an efficiency of 34.6%.
Scientists design all-back-contact transparent solar cell
A research team from South Korea’s Ulsan National Institute of Science & Technology (UNIST) has designed a wire-free transparent solar cell and module with all electrical contacts placed on the rear side. A 16 cm² module achieved a power conversion efficiency of 14.7% and successfully charged a smartphone using natural sunlight.
SECI launches tender for 2 GW of solar
Solar Energy Corp. of India (SECI) has launched a tender to select developers for 1 GW of interstate transmission system (ISTS) connected solar PV power projects and additional capacity of up to 1 GW to be awarded through Greenshoe option. Bidding closes on Oct. 4.
Silfab launches 640 W utility-scale solar panels
The Canada-based manufacturer said its new panels have a temperature coefficient of -0.29% per C and an efficiency of up to 22.92%. They come with a 30-year power output guarantee for 89.3% of the initial yield.
Italy’s first agrivoltaic tenders draws bids for 1.7 GW
Italy’s Ministry of the Environment and Energy Security (MASE) says it has received 643 bids totaling 1.7 GW in its first agrivoltaic tender. About 56% of the proposals have come from the country’s sunny southern regions.
Increasing potential of silicon clathrate films for photovoltaics
Researchers led by scientists from CNRS in France are exploring an exotic form of silicon called silicon clathrate as a material for energy applications, including photovoltaics. Mastering the synthesis and using appropriate characterizations are key elements towards potential applications. Significant progress is being made for the fabrication of functional devices.
Aluminium-polymer battery for stationary electricity storage
The device developed by TU Bergakademie Freiberg researchers uses aluminum as an anode, graphite as a cathode, and a polymer-based solid electrolyte. It is being validated and further developed for industrial production. The goal is storage capacity of 10 kWh.
