[SMM PV Flash] PV-grade EVA Prices Slightly Rise, Downstream Acceptance Remains Weak

A research team from the Institute of Chemistry, Chinese Academy of Sciences (hereinafter referred to as ICCAS) has boosted the power conversion efficiency of perovskite-organic tandem solar cells to 28.04%, once again setting a new world record for such devices. The related research was published in *Nature* on July 13. The corresponding author of the paper, Li Yongfang, an academician of the Chinese Academy of Sciences and a researcher at ICCAS, stated that perovskite-organic tandem solar cells combine the advantages of light weight, flexibility, and high specific power. They can be widely applied in ground-based scenarios such as buildings, transportation, and wearable electronic devices, and can also play a positive role in space fields including satellites, space stations, and deep-space exploration, serving as a vital energy guarantee for humanity’s march into space. "This kind of cell is thin, lightweight, and portable; it can easily be placed in a backpack and carried around. During outdoor trips, you simply unfold it to charge electronic devices like mobile phones," Li Yongfang told *China Science Daily*.

[SMM Silicon-Based PV Morning Meeting Summary: Wafer Top-Tier Player's Production Cut Plan Adjustment, Solar Cell Industry Inventory Buildup Continues] Wafers: According to the latest SMM survey, a top-tier player adjusted its production cut plan, with actual output flat MoM from June. Additionally, integrated enterprises also ramped up production, and the total volume and distribution ratios of external toll processing were adjusted. Overall, July was down about 2% MoM from June. Solar cells: This week, the industry's total inventory rose again WoW, and the market continued to be in a state of inventory buildup, with producers' shipment pressure further intensifying.

On July 10, the SOLAR & STORAGE EXPO 2026 Pakistan will be held at the Lahore International Expo Centre. Hoymiles, together with local partners, will participate, focusing on core needs such as home emergency backup power, PV energy management, and industrial and commercial energy optimization, and will highlight the HIS/HIT series hybrid energy storage inverters, the LB low-voltage ESS battery, and the HoyUItra 261A industrial and commercial ESS all-in-one unit, deeply implementing localized energy solutions and fully supporting Pakistan’s energy transition.
