EPFL unveils perovskite-silicon tandem solar cell with certified efficiency of 30.9%
The tandem solar cell is based on a perovskite top cell treated with an additive known as 2,3,4,5,6-pentafluorobenzylphosphonic acid (pFBPA), which reportedly improves its power conversion efficiency and fill factor. The tandem device also integrates a bottom heterojunction silicon cell made with a 190-μm-thick, 2 Ω.cm, n-type, float-zone, shiny-etched monocrystalline wafer.
Stepping up critical mineral production remains crucial for India’s energy security: ICRA
Advancement in mineral processing and beneficiation technology remains critical for commercialisation of domestic critical mineral resources.
All-perovskite tandem PV cell based on carboranes hits 27.2% efficiency
Researchers have developed a thermal regulation strategy to improve the performance of inverted tin-lead perovskite tech for all-perovskite tandem solar cells. It has an efficiency of 23.4% and contributed to a 27.2% efficiency in a tandem cell while ensuring stability.
Pahal Solar introduces 595 Wp TOPCon bifacial panel with 23.03% efficiency
India’s Pahal Solar has launched n-type TOPCon glass-backsheet modules in peak power outputs of 560 W to 595 W with front-side efficiencies of 21.68% to 23.03%.
Silfab Solar secures funds to develop US-made back-contact n-type PV cells
Silfab Solar is one of seven recipients of US Department of Energy (DoE) funding for projects that will rely on dual-use PV technologies to electrify buildings, decarbonize the transportation sector, and reduce land-use conflicts.
Daewoo launches hybrid battery-inverters for residential PV
Daewoo’s new hybrid inverters feature LiFePO4 batteries. They are available in six variants, with power ratings ranging from 0.5 kVA to 10 kVA.
The U.S. multi-pronged approach to onshoring solar manufacturing
The U.S. aims for a domestic solar supply chain, but the industry’s capacity to serve the early stages in solar manufacturing are minimal. Will its recent industrial policy efforts make a difference?
Novel hydrophobic, antireflective coating for solar glass
Slovakian scientists have developed a novel hydrophobic, antireflective coating for solar glass with a silica-titania thin film as the bottom layer and an inorganic-organic upper layer made of silica modified with triethoxy(octyl)silane. This new coating increases glass transmittance by 7% compared to uncoated glass.
Competition, oversupply to reduce n-type solar module prices
Global solar demand will continue to grow in 2024, with module demand likely to reach 492 GW to 538 GW. Amy Fang, a senior analyst at InfoLink, looks at module demand and supply chain inventories in a market still affected by oversupply.
U.S. scientists demonstrate 25%-efficient perovskite-cadmium tandem solar cell
The researchers say the cell has a top perovskite cell with a transparent back contact made of indium zinc oxide and a commercially established cadmium telluride bottom device. They claim the champion tandem cell has the potential to reach a 30% efficiency.
