Researchers design 31%-efficient perovskite solar cell based on calcium nitrogen iodide
An international team has demonstrated a perovskite solar cell relying on inorganic calcium nitrogen iodide (Ca3NI3) perovskite and has found this absorber material offers advantages such as tunable bandgap and resistance to heat. The device achieved a fill factor of 81.68%.
Ensemble techniques for solar energy forecasts
A Chinese research group has sought to understand the relative performance of two weather prediction techniques based on ensemble modeling for solar energy forecasts. The scientists applied the two methods in combination with three classical post-processing methods.
Mooring system design for offshore floating photovoltaics
Researchers in China have compared the performance of catenary and taut mooring systems for offshore floating PV systems. They found that the taut system offers a higher degree of reliability in shallow water environments with severe tidal variations.
Nhoa Energy commissions battery storage project in Taiwan
Nhoa Energy, an Italian developer, has commissioned a battery energy storage project for Taiwan Cement Group in Yilan county, Taiwan, with a capacity exceeding 120 MWh.
India releases draft guidelines for residential rooftop solar subsidies
India’s Ministry of New and Renewable Energy (MNRE) has released draft guidelines for the PM Surya Ghar: Muft Bijli Yojana scheme, which aims to install rooftop solar plants in 10 million households, with subsidy support from the central government.
Sunman launches glass-free balcony solar modules
The Chinese manufacturer said its new frameless module can be installed on a balcony through nylon cable ties, without the need for any mounting structure. The new product features a power output of 200 W and a power conversion efficiency of 16.2%.
System design for PV-driven hybrid EV charging stations
Researchers in India have simulated a 4 kW solar power-based hybrid electric vehicle (EV) charging station using a three-stage charging strategy and found that the station is capable of charging 10–12 EVs with 48 V 30 Ah lithium-ion batteries.
The Hydrogen Stream: Vale opens hydrogen metallurgy lab in China
Vale and Central South University have launched a joint laboratory for low-carbon and hydrogen metallurgy in Changsha, in China’s Hunan province, while Nippon Steel has secured approval to acquire U.S. Steel.
Chinese PV Industry Brief: Huasun signs wafer, cell supply deals
Huasun has signed two deals with Leascend Group, including a monocrystalline silicon wafer supply agreement, while GCL Technology has agreed to supply Longi Green Energy Technology with 425,000 tons of N-type granular silicon to the end of 2026.
Making the case for concentrated solar power
Dismissed by many in the solar industry as an overly-complex, outdated technology, concentrated solar power (CSP) is set for a comeback thanks to a scaled-down, modular approach.
