JUNHE® 2580 Solar Cell Cleaning Additive

Driven by the global energy transition and carbon neutrality goals, the photovoltaic industry is experiencing rapid growth. The cleaning efficiency of solar cells directly affects their power generation performance and lifespan. Traditional cleaning processes rely on strong oxidizing agents such as hydrogen peroxide (H₂O₂), which pose environmental pollution risks, incur high costs, and struggle to completely remove complex contaminants. In this context, JUNHE® 2580 Cleaning Additive has emerged as a key solution for the green upgrade of the photovoltaic industry chain. 

1. Industry Pain Points Breakthrough

   During photovoltaic silicon wafer production, wafers are prone to contamination by oils, polishing residues, metal ions, and microparticles. Traditional cleaning processes rely heavily on high-concentration hydrogen peroxide, which not only carries risks of oxidative by-products but can also damage the wafer surface, leading to decreased cell conversion efficiency. Moreover, hydrogen peroxide systems have limited effectiveness against stubborn organic contaminants like epoxy resin and photoresist residues, and the associated wastewater treatment costs are high. JUNHE® 2580, with its innovative formulation, achieves efficient cleaning of heavily contaminated wafers while reducing dependence on oxidizing agents, meeting the photovoltaic industry’s dual demands for safety, environmental protection, and high efficiency.

2. Technical Synergistic Innovation

   This product leverages enhanced surfactant action and chemical synergism, combined with nano-scale dispersion technology, to rapidly penetrate the wafer’s microstructured surface, breaking down complex organics and removing micron- and submicron-sized particles. Its formulation avoids the use of traditional strong acids and bases, significantly reducing environmental impact, simplifying process steps, and conserving energy and water resources.

3. Market Demand Driven

   With the widespread adoption of new cell technologies such as PERC, TOPCon, and HJT, wafer surface cleanliness requirements have become more stringent. JUNHE® 2580 precisely adapts to different process stages (e.g., texturing, etching, pre-coating cleaning), helping photovoltaic manufacturers improve yield rates, reduce operation and maintenance costs, and comply with environmental regulations such as the EU RoHS and REACH directives, thereby enhancing its competitiveness in the international market.

JUNHE® 2580 Cleaning Additive is a product specially designed for the cleaning process of photovoltaic solar cells. By enhancing surfactant activity and chemical synergy, it significantly improves the cleaning ability of heavily contaminated silicon wafers—such as those with oil stains and polishing residues—and demonstrates superior effectiveness against stubborn contaminants. Its innovative formulation can replace traditional hydrogen peroxide (H₂O₂) systems, reducing reliance on oxidizing agents while efficiently breaking down organic matter and removing micron- and submicron-sized particulate impurities, thereby lowering the risk of surface contamination.
