CIGS solar cell based on ultrathin glass substrate achieves record efficiency of 17.81%
Korean researchers have fabricated a CIGS cell with a 90 μm-thick UTG provided by Korean specialist Unique Technology Integral. The device also utilizes a cadmium-free buffer layer made of zinc oxide and magnesium oxide, instead of commonly used 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.
Germany’s PV installations down sharply in March
Germany installed just 787.2 MW of new PV capacity in March – the lowest monthly total since December 2022.
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.
Texas Senate passes anti-solar, wind bill
The bill places permit restrictions, fees and new regulatory requirements for solar and wind projects.
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.
Fronius launches hybrid inverters for residential, commercial applications
The Austrian manufacturer said its new hybrid inverters can increase the usable output of the PV system to up to 150%. They are available in six version with rated AC power ranging from 15 kW to 33.3 kW.
Belgian grid operator warns of PV overproduction, curtailment in spring
Belgian grid operator Elia says that rapid solar fleet growth is driving earlier seasonal overproduction peaks, raising curtailment risks this spring. It plans to expand flexibility measures to stabilize the high-voltage network.
