Four-terminal tandem perovskite solar cell design with 30.14% efficiency
The lead-free solar cell was modeled via a three-dimensional finite element method by an Iranian research group. The cell was designed without the buffer layer and with the addition of anti-reflection layer (ARL) strategies, as well as the use of periodic nano-texture patterns.
JinkoSolar achieves 25.7% efficiency for n-type TOPCon solar cell
Manufacturing giant JinkoSolar has set another world record for n-type solar cell efficiencies with its TOPCon technology, this time pushing to 25.7%. The new world record was confirmed by China’s National Institute of Metrology.
Sun Cable reveals full extent of its giant solar-plus-storage project in Australia
Singapore-based Sun Cable has submitted its Environmental Impact Statement to the Northern Territory Environment Protection Authority. The document reveals the full extent of the project’s enormity, specifically a 17-20 GW solar farm tied to 36-42 GWh of battery energy storage, which is set to be transmitted by subsea cables to Singapore.
Utility scale solar inverters need improved commissioning and upkeep
Recurring power grid faults are testing solar inverter reactions, and have exposed issues that could seemingly be solved by improvements to commissioning, operations, and maintenance.
The Hydrogen Stream: Fuel cell that uses iron instead of expensive platinum
In other news, Hydrofuel Canada developed hollow hybrid plasmonic nanocages to create an electrocatalyst for ammonia synthesis from nitrogen (N2) and water (H2O) and said green hydrogen could be separated from this ammonia and sold at about $1.50 per kilogram. Furthermore, Norway’s Aker Horizons and Statkraft are exploring green hydrogen and ammonia production opportunities in India and Brazil, targeting local steel and fertilizer industries.
Chinese PV Industry Brief: Tongwei wants to reach 1 million MT polysilicon capacity by 2026
Tongwei also announced it wants to expand its solar cell capacity to 70 GW by the end of 2022 and 102 GW by the end of 2023.
Malaysia’s water reservoir to host 150 MW floating solar plant
The floating facility will be built by Japan’s Shizen Energy and will sell power under unspecified conditions to local utility Syarikat Air Melaka Bhd (SAMB).
Ionic liquid-based perovskite solar cell with 22.86% efficiency
A Swiss-Japanese research group has used ionic liquids doping to improve the efficiency and stability of perovskite solar cells. Their champion device showed an open-circuit voltage of 1.16 V, a short-circuit current of 24.03 (mA cm−2), and a fill factor of 0.818. It was also able to retain around 95% of its initial efficiency after 1,000 hours of operation.
EBRD stumps up €46m for ‘Poland’s biggest solar park’
The London-based international lender has provided finance for the “up to 286 MW” project alongside Poland’s two biggest retail banks.
German solar supplier lands fresh $3m from EU entity
Redavia, which leases plug-and-play solar systems to commercial clients in Africa, secured the fresh credit line after settling a previous $2 million loan supplied by the EDFI ElectriFI European development finance institution.
