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.
Irish and UK grids linked via 500 MW subsea HVDC cable
The Greenlink Interconnector comprises two high-voltage direct current (HVDC) cables reaching across the Irish Sea connecting the grids of Ireland and the United Kingdom at the Great Island substation in County Wexford and Pembroke substation in Pembrokeshire, Wales.
UL battery safety standard updated for new storage chemistries
Underwriters Laboratories (UL) says the fifth edition of its ANSI/CAN/UL 9540A standard addresses technology such as sodium-ion batteries and new use-cases including rooftop installations.
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.
Average silver price up 21% in 2024, says Silver Institute
Demand for silver in the PV industry hit 197.6 million ounces in 2024, according to a new report from the Silver Institute. It says the average silver price stood at $28.27 per troy ounce last year, up from $23.35 in 2023.
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
Fraunhofer ISE developing heterojunction solar cells with silver consumption of less than 2 mg per W
Researchers at the German institute are seeking to reduce silver use in heterojunction PV devices under the umbrella of an extensive research projects. Among their recent achievements there is the fabrication of a heterojunction cell that requires a minimal silver consumption of only 1.4 mg per W.
CATL unveils 587 Ah battery energy storage cell
The competition in the development of large-capacity cells is heating up, with the industry’s top player stepping up to shape the new standard in the battery energy storage space.
Fire risks in industrial rooftop solar systems due to poor installation
Clean Energy Associates (CEA) has inspected more than 600 industrial PV systems and has found widespread safety risks, largely stemming from poor installation practices, but many issues are easily identifiable and fixable.
