Oct 21, 2026In the global commercialization of third-generation photovoltaic technology, environmental compliance has long been a sword of Damocles hanging over the perovskite industry. SunFlex New Energy, leveraging its proprietary molecular-level lead immobilization technology and end-to-end green manufacturing system, has become the first flexible perovskite company in the world to pass all five major international environmental certifications in a single round — EU RoHS, EU REACH, EU POPs, US TSCA, and California Proposition 65 — all issued by TÜV SÜD Germany.
This is more than an authoritative endorsement of product safety. It represents a fundamental technological resolution of the industry's longstanding "lead contamination" concern, clearing the most critical barrier for flexible perovskite to scale into consumer electronics, building-integrated photovoltaics, and other civil applications.
1. EU RoHS: Gateway to the European Electronics Market
What it covers: Mandatory restriction of 10 hazardous substances, with lead and 9 others capped at 1,000 ppm, and cadmium at 100 ppm.
SunFlex advantage: Lead content is far below that of conventional crystalline silicon modules — the ultra-trace lead in the perovskite crystal structure is significantly less than the leaded solder ribbons used in crystalline silicon PV. Under extreme conditions, lead ion leaching falls below the limit of detection, achieving "physically present, environmentally risk-free."
2. EU REACH: Full Lifecycle Passport for Chemicals
What it covers: The world's most stringent chemical management regime — "no data, no market." Over 250 Substances of Very High Concern (SVHCs) are regulated; any concentration above 0.1% triggers mandatory notification.
SunFlex advantage: All SVHC concentrations are below the 0.1% notification threshold. Customers incur zero additional compliance costs.
3. EU POPs: Ban on Persistent Organic Pollutants
What it covers: Grounded in the Stockholm Convention, this regulation bans 30+ persistent, highly toxic organic pollutants — most at "non-detect" levels.
SunFlex advantage: Through green solvent substitution and eco-friendly encapsulation technology, SunFlex has completely eliminated the chlorinated and brominated flame retardants traditionally used in photovoltaics. All POPs substances were tested non-detect.
4. US TSCA: America's Chemical Safety Gatekeeper
What it covers: Mandatory EPA requirement — all new chemical substances must pass comprehensive toxicological and environmental risk assessment before entering the U.S. market.
SunFlex advantage: SunFlex is the first Chinese perovskite company to receive U.S. EPA safety recognition for perovskite materials, demonstrating no unacceptable risk under normal or reasonably foreseeable conditions of use.
5. California Proposition 65: Guardian of Consumer Right to Know
What it covers: A mandatory California regulation covering 900+ carcinogenic and reproductive toxicants. If exposure exceeds the safe harbor threshold (NSRL/MADL), a warning label is required.
SunFlex advantage: Through multi-layered lead-locking technology, lead exposure levels are well below the No Significant Risk Level (NSRL). SunFlex products are perovskite-based products that do not require a Proposition 65 warning label.
