All solar cell efficiencies at a glance – updated
The research group led by Professor Martin Green has published Version 65 of the solar cell efficiency tables. There are 17 new results reported in the new version.
Perovskite-silicon tandem solar cell based on indium oxide buffer layer achieves 30.04% efficiency
Researchers in China have fabricated a perovskite-silicon tandem solar cell that utilizes an indium oxide sputtering buffer layer to protect the perovskite absorber and the electron transport layer from potential damages arising from the electrode deposition process. The new layer not only ensured this protection but also showed strong optical and electrical properties.
Looming Trump tariffs drive rush on US imports, push shipping costs higher
Freight costs are rising as businesses rush to import goods ahead of higher tariffs promised by US President-elect Donald Trump on Chinese and European products.
Longi unveils heterojunction BC solar cells with 27.3% efficiency
The Chinese manufacturer said the device is based on dense passivating contacts that reduce parasitic light absorption and improve passivation. It used a streamlined manufacturing technique that is reportedly about one-third more effective than TOPCon mainstream technology.
Solar modules now selling for less than €0.06/W in Europe
Solar module prices reached a new low last week, says Leen van Bellen, business development manager Europe for Search4Solar, a European purchasing and selling platform for solar products. He tells pv magazine that prices will remain low in the short term.
Nepal allocates 960 MW in PV tender with lowest bid of $0.037/kWh
The Nepalese authorities had originally planned to allocate 800 MW of PV capacity through the procurement exercise. The 64 selected projects range in size from 5 MW to 50 MW.
Italian startup offers green hydrogen generation, storage system for homes
Italian startup Hybitat Srl has developed a hydrogen production and storage system for long-term storage of surplus residential and commercial solar power. The system includes a main unit with an electrolyzer and fuel cell, as well as a storage unit with 3 kg of hydrogen capacity and 100 kWh of energy capacity.
What happens when malware hits PV systems
A random malware variant affected about 800 remote monitoring devices at ground-mounted PV plants in Japan in May 2024. Tokyo-based cybersecurity firm Girasol Energy has told pv magazine what happened and how PV asset owners can protect themselves against such incidents.
KAUST, Helmholtz-Zentrum Berlin present 31.2%-efficient blade-coated perovskite-silicon tandem solar cell
The perovskite-silicon tandem device has a two terminal configuration and a 2D perovskite layers at the bottom interface. It was able to retain around 80% of its initial efficiency for 1,700 h.
JinkoSolar announces new TOPCon solar modules with efficiency of 24.8%
The Chinese manufacturer said the new Tiger Neo 3.0 modules are available in two versions with outputs of 495 W and 670 W.
