1. Our Goal is to support YOU PV-200 Innovation of Power Generation for Solar Cell Sun Reflection Transmittance Sun Light

2. 90.2% 92.7% 95.6% Uncoated Single Side CoatedBoth Sides Coated Transmittance 5% Up Power 192.4 Wp Power 196.2 Wp Power 199.3 Wp Power Generation 3.5% UP 1. Anti-Reflection Effect and Power Generation by PV-200 Decreased Reflection ~4% Increased Transmittance ~6% PV-200 Coating Layer Sun Light 100%

3. 2. Self-Cleaning Effect and Power Generation by PV-200 Elimination Process of Contaminant from Substrate by Hydophilicity Sun Light PV-200 Layer Substrate Dirty Contaminant Rain (Water) OH Genesis of Hydrophilicity Elimination of Contaminant by Hydrophilicity 185 190 195 200 205 210 Start123 Uncoated PV-200 Coated Power Generation (Wp) Time (month) Power Generation by Self-Cleaning Effect; Maximum ~5% A/R Effect A/R Effect(3.5%<) Results of Outdoor Test Mechanism of Self-Cleaning by PV-200

4. 3. Economic Benefits Expense of PV-200 treatment Power Generation by Self-cleaning Power Generation by increased Transmittance Environmental Protection from Air Pollution Three creative economic benefits; Firstly, more power generation by the increase of initial transmittance, secondly, more power generation by self-cleaning effect and finally environmental protection from air pollution covers the initial expense of photocatalytic treatment 4. Summary  Almost Maximum Transmittance and Minimum Reflectance   Semi-Permanent coating – same as the lifetime of the Panel   Eco-friendly - less frequent use of water and detergents  Maximum power generation - Make Money Protection of Glass-Surface from the action of natural forces Simple Coating Process by one Spraying or Dipping method
