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).
WorldOne Energies commissions 1.2 GW solar module line
WorldOne Energies has commissioned a 1.2 GW solar module manufacturing line that will produce its Supreme series n-type tunnel oxide passivated contact (TOPCon) panels.
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.
PV-driven heating, cooling system for supermarkets
Scientists in China have developed a novel PV-powered cooling and heating system that combines a water-cooled gas cooler and an air-cooled gas cooler. The system went through a series of simulations and showed it can potentially achieve a coefficient of performance of up to 7.34.
Longi achieves 34.85% efficiency for two-terminal tandem perovskite solar cell
The result was confirmed by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL).
ReNew inaugurates 1.3 GWp solar project in northwestern India
ReNew has inaugurated a 1.3 GWp solar project in Rajasthan, India, using mostly in-house solar panels to supply power at INR 2.18 ($0.026)/kWh. The project spans 3,500 acres and is expected to generate 2,490 million units of electricity per year.
CIGS cell with ultra-thin glass substrate hits record efficiency of 17.81%
South Korean researchers have fabricated a copper indium gallium selenide (CIGS) solar cell with a 90 μm-thick UTG provided by South Korea’s Unique Technology Integral. The device uses a cadmium-free buffer layer made of zinc oxide and magnesium oxide, instead of cadmium sulfide.
Testing floating PV at different heights
Scientists have tested the performance of floating PV panels at a height of 800 mm and 250 mm above their floating structures. Their thermal and electrical performance was compared to that of a reference land-based system and the highest panel was found to show the greatest cooling effect.
Rept Battero launches 392 Ah cell, 6.26 MWh storage system
Rept Battero’s new 392 Ah battery energy storage system (BESS) cell is an all-rounder, with the same size but increased energy density over a previously manufactured cell.
China identifies major high-purity quartz deposits for PV industry
China has identified two new high-purity quartz deposits as it seeks to localize supply for solar and semiconductor production and reduce dependence on US imports
