Photovoltaics for atmospheric water harvesting
A scientist in Turkey has simulated eight PV-supported hybrid atmospheric water harvesting systems and compared their performances. They were all considered to operate with R1233zd(E), R1234yf, and R600a, as well as R32 refrigerants. The required PV system size was as low as 20 m2.
Tongwei achieves 91.7% bifaciality factor for 722 W TOPCon solar module
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.
U.S. startup offers tin oxide, nickel oxide materials for flexible perovskite solar cells, modules
Sofab Inks, a spinoff of University of Louisville in the United States, says its transport layer materials enable perovskite solar cells with greater stability, efficiency, and scalability compared to incumbent materials.
Germany’s day-ahead market posts 389 hours of negative prices in H1
Germany recorded 141 hours of negative day-ahead electricity prices in June, just below the record set in May, bringing the first-half total close to the full-year figure for 2023.
Trinasolar targeting ‘high-value’ markets
Yang Bao, Trinasolar’s president of global sales and marketing, recently spoke with pv magazine about the company’s strategy for the solar and energy storage business.
Guyana launches net billing scheme for rooftop PV
Guyana has introduced a net billing program for rooftop PV systems up to 100 kW and for larger systems based on a customer’s maximum demand. It aims to expand distributed generation and reduce grid dependency.
Photovoltaics for agromining
Researchers in France have investigated how photovoltaic power generation can be combined with the growth of hyperaccumulating plants in disused, contaminated brownfield land and have found this combination could help increase the profitability of the so-called agromining – a plant-based approach to cleaning up contaminated environments.
China to deploy 253 GW of PV for desert control in arid north
China plans to install 253 GW of solar capacity and restore more than 670,000 hectares of degraded land by 2030 under a large-scale desert PV program in its northern and northwestern regions. It aims to curb desertification and expand renewable energy deployment.
LiNa Energy opens sodium battery pilot manufacturing line in UK
10 kWh sodium-metal-chloride batteries will be build at new site in Lancaster, England. Start-up LiNa is targeting markets with harsh climates during initial rollout and intends to produce 100 kWh systems following 10 kWh trial projects.
Brazilian energy storage hampered by technical challenges, lack of regulation
While Brazil wastes billions of real on curtailment, the electricity sector is demanding urgent action on an energy storage capacity reserve auction which is now not expected until 2026. ‘What is missing is the courage to unlock the market,’ said Greener CEO Marcio Takata.
