Germany’s January-October solar additions reach 13 GW
The Federal Network Agency (Bundesnetzagentur) says Germany’s installation pace reflects shifting demand patterns between ground-mounted and rooftop PV systems.
JA Solar builds inverted perovskite solar cell with 26.7% efficiency
The Chinese manufacturer said the cell uses a multifunctional organic ammonium salt to improve interfacial engineering between the perovskite absorber and the electron transport layers. The device also achieved 24.5% efficiency when scaled up to a 1 cm² active area.
Reducing PV module temperature with twisted tape
Researchers in Iran have investigated how twisted tape in water-cooled channels can enhance heat transfer in solar modules. They have used a computer simulation to analyze the new approach with different parameters and have found the panels’ ectrical efficiency increased by up to 11.84%.
Nanostructured antireflective coating for gallium arsenide solar cells
A Spanish research team demonstrated a broadband antireflective coating for gallium arsenide solar cells. Based on thermally oxidized gallium nanoparticles, the nanostructured coating reduced reflectance by 30% across the solar spectrum, and increased solar cell performance by 10%.
Chinese PV Industry Brief: DKEM files patent lawsuit against silver paste rival
Wuxi DK Electronic Materials (DKEM) has filed a patent lawsuit against Zhejiang Guangda Electronic Technology over alleged infringement of its conductive silver-paste patents.
S-5! launches new clamp for solar carports
The US mounting system provider said its new product is designed to fit both Cee and Zee purlin-framed structures. It features a bottom-oriented setscrew.
Fraunhofer ISE builds first perovskite-silicon tandem solar cell with copper metallization
Using the mask-and-plate copper metallization technique, scientists at the German research center fabricated a 1.21 cm² perovskite–silicon tandem solar cell featuring a heterojunction bottom device. The cell achieved an efficiency of 19.35%, reportedly the highest value reached to date for this cell type using galvanic front metallization.
OPIS Global Polysilicon Marker inches higher as US Section 232 uncertainty lingers
