Research shows high-albedo ground reflectors increase bifacial solar plant yield by up to 4.5%
Tests conducted by Canadian researchers at the NREL’s testing field in Colorado have shown that ground reflectors based on high-density polyethylene can significantly increase bifacial PV plant performance. They stressed the profitability of this technology is strictly dependent on the location and warned avoiding to combine it with inverter clipping.
Longi announces 27.30% efficiency for heterojunction back contact solar cell
The Chinese module manufacturer said the new efficiency record was confirmed by Germany’s Institute for Solar Energy Research (ISFH).
Korean researchers build vertical solar panels with low reflection losses
The modules are equipped with Maxeon solar cells and a microprism sheet that reportedly upholds a transmittance exceeding 99%. The microprism array is imprinted onto a PET sheet using the roll-to- roll embossing technique.
Global solar manufacturing sector now at 50% utilization rate, says IEA
The International Energy Agency (IEA) says that global solar cell and module manufacturing capacity grew by around 550 GW in 2023. It reports that around 80% of the global PV manufacturing industry is currently concentrated in China, while India and the United States each hold a 5% share. Europe accounts for a mere 1%.
NREL interactive chart of solar cell efficiency now including ‘hybrid tandems’
The new cell category includes perovskite/silicon, perovskite/CIGS, III-V/silicon and perovskite/organic tandem PV devices. It will list the absolute record efficiency for all-perovskite, two-terminal tandems regardless of the number of junctions.
OCI increases production capacity at Malaysian polysilicon factory
OCI has revealed plans to invest $617.9 million to expand production at its Malaysian manufacturing facility from 35,000 to 56,600 metric tons.
Norwegian startup unveils CO2 water-to-water heat pump
Tequs said its new plug-and-play heat pump can deliver up to 90 C of heat for space heating, air conditioning, and domestic hot water. The new product is available in eight versions with capacity ranging from 17 kW to 268 kW.
UNSW researchers warn of surprising TOPCon solar module vulnerabilities
Researchers at the University of New South Wales claim to have identified three TOPCon panel failure types that are absent in PERC products. They explained that these failures may occur when the modules are exposed to high humidity and contaminants before encapsulation.
Korean researchers build 8 kW solid oxide electrolysis cell that can produce 5.7 kg of hydrogen per day
The Korea Institute of Energy Research has developed a solid oxide electrolysis cell stack that uses a special kind of separator plate to ensure proper flow of hydrogen and oxigen after water splitting. Samsung Electro-Mechanics and Bumhan Industries are now cooperating with the research center to improve relevant manufacturing process.
