TU Delft researchers build 23.4%-efficient heterojunction solar cell with localized front contacts
Researchers at the Delft University of Technology have developed a top-down processing method localized the front contact in heterojunction solar cells. The new technique reportedly improves a cell’s short-circuit current density enabling higher power conversion efficiency.
1Komma5° releases residential battery for non-PV homeowners
1Komma5° has launched PowerHarvester, a lithium iron phosphate battery system for residential customers without solar. It is offering six power classes and storage capacities from 7.7 kWh to 27.2 kWh.
Rhoss launches reversible heat pumps
Conceived for industrial applications, the novel heat pumps can reportedly deliver hot water at 65 C from -10 C up to 35 C of external air, and hot water at 55 C down to -20 C of external air. Their coefficient of performance reaches up to 3.60.
Low-cost conductive quantum dot inks for photovoltaics
An international research team has developed a method to economically synthesize and stabilize conductive colloidal quantum dot inks for solar applications. When used to make quantum dot films in large area PV devices they enabled a certified efficiency of 10%, with lab-sized cells based on the ink material achieving 13.40% efficiency.
TBEA unveils 400 kW string PCS, 6.25 MWh battery
The Chinese manufacturer has designed a new high-density 400 kW power conversion system (PCS) and 6.25 MWh battery energy storage system (BESS) to cut costs and boost deployment speed.
Gautam Solar presents 23.69%-efficient 640 W TOPCon solar module
The Indian manufacturer said its new TOPCon solar panel is based on rectangular bifacial solar cells and is certified by the Bureau of Indian Standards (BIS).
EVA-induced degradation has significant impact on power losses in TOPCon solar modules
New research from UNSW shows that EVA-encapsulated TOPCon solar modules under damp-heat testing can suffer significant power losses and fill factor drops. The study describes metallization degradation mechanisms driven by EVA-generated contaminants and demonstrates the effectiveness of metallization adjustments in reducing EVA-induced degradation rates
New tool aims to cut costly hail losses in utility-scale solar
Hail damage accounts for just 2% of filed solar insurance claims but more than 50% of total costs, according to VDE Americas.
U.S. Commerce Department slaps unexpectedly high tariffs on solar imports
Coalition trade lawyer says the U.S. Department of Commerce’s final tariffs on solar cells and modules from Cambodia, Malaysia, Thailand and Vietnam are among the highest rates he’s ever seen.
