JinkoSolar claims 33.84% efficiency for perovskite-silicon tandem solar cell
Independent testing of JinkoSolar’s N-type TOPCon-based perovskite tandem solar cell has achieved a conversion efficiency of 33.84%, surpassing the company’s previous record of 33.24%,
UK researchers trial agrivoltaics with large-scale hydrogen production in Australia
United Kingdom scientists have simulated how a 1 GW off-grid agrivoltaic facility may be used to fuel hydrogen fuel electric cell vehicles across Africa, the USA, China, Europe and Australia showing the proposed combination could provide a levelised cost of hydrogen ranging from $6.05/kg to $12.61/kg.
LCOE not correct optimisation parameter of PV plants, say researchers
New research shows the importance of considering power plant dispatchability in PV project planning. An international team of scientists claim assessing a project’s levelised cost of energy could be misleading, especially with variable and sometimes negative electricity prices.
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.
Sunways unveils three-phase inverters for rooftop PV
Sunways’ new three-phase inverters have efficiency ratings of up to 98.6% and European efficiency ratings of 98.2%. They are available in five versions, with power outputs ranging from 15 kW to 30 kW.
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.
GoodWe launches residential solar carport
GoodWe has developed a residential solar carport that features its Polaris building-integrated PV (BIPV) panels. The carport, which is available in 4.8 kW and 8.0 kW variants, is designed to host one or two vehicles, respectively.
Trina Solar claims 25.9% efficiency for large-area industrial TOPCon solar cells
The Chinese manufacturer said the result was confirmed by Germany’s Institute for Solar Energy Research in Hamelin.
JinkoSolar, Trina say TOPCon modules outperform p-type back-contact panels
JinkoSolar and Trina Solar have separately reported that on-field testing shows tunnel oxide passivated contact (TOPCon) solar modules outperform p-type back-contact PV modules in monthly power generation.
General Motors launches residential storage system
The United States-based automotive manufacturing company said its new storage system offers the option of integrating with PV systems. It can be scaled to reach a capacity of up to 35.4 kWh, which the company said would enable approximately 20 hours of storage.
