The quality assurance firm updated its inverter manufacturer financial stability ranking with Kstar Science and Technology, APSystems and Delta Electronics in the top three spots. It reported 19 manufacturers showing “strong financial resilience” based on Altman-Z scores.

In a new scientific paper, the Chinese solar manufacturer explained that the 27.81%-efficient hybrid interdigitated back-contact cell it unveiled in April is based on passivated tunneling contacts and dielectric passivation layers, while also incorporating both n-type and p-type contacts.

PVV Infra Ltd has signed a memorandum of understanding with the Andhra Pradesh Economic Development Board (APEDB) to invest around INR 650 crore (73.4 million) in establishing a 1 GW n-type TOPCon solar cell manufacturing facility in Visakhapatnam.

The French manufacturer has strengthened its financing plan to more than €220 million following the arrival of two new investors It is advancing its TOPCon gigafactory project in Hambach, northeastern France. The company says it has finalized its industrial model and secured a substantial customer portfolio.

The quality assurance provider reported India-based Insolation Energy, Waaree Renewable Technologies, and Solex Energy retained the top three positions in its Altmann-Z score-based quarterly ranking. Its analysts noted the number of companies with healthier scores increased from 9 to 11.

The Chinese manufacturer said its new T5 Pro modules featues high power density and low-current, low-resistance profile. The series has a power output of 480 W to 760 W and a power conversion efficiency of up to 25.17%.

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.

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%.

Wuxi DK Electronic Materials (DKEM) has filed a patent lawsuit against Zhejiang Guangda Electronic Technology over alleged infringement of its conductive silver-paste patents.

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.
