The New Age of Solar has Arrived I’d put my money on the sun and solar energy . What a source of power! I hope we don’t have to wait until oil and coal run out before we tackle that . - Thomas A . Edison, 1931 Page 5 John Rhee | February 2021

The Sun Provides Sunlight penetrates clouds, atmosphere, rain, pollution and other elements to provide us energy. At ground level, earth receives 1,000 watts per meter square from the sun. Our Most Sustainable Energy Source Page 6 John Rhee | February 2021

Reliable and Efficient The sun will most certainly rise tomorrow, and our talent is harnessing its enormous power. SOLAR ENERGY Page 7 John Rhee | February 2021 “That free fusion reactor in the sky conveniently converts ~ 4 million tons of mass into energy every second . We just need to catch an extremely tiny amount of it to power all of civilization . ” - Elon Musk, Oct . 2020

TRANSPARENT Generate power from natural sunlight, shaded conditions, and artificial lighting PERFORMANCE ULTRA THIN Generate electricity on transparent glass, plastic surfaces, and flexible substrates Only 1/100th the thickness of a human hair Engineered for fast throughput manufacturing Electricity Generating Coatings Case In Point: LiquidElectricity™ Page 8 John Rhee | February 2021

LiquidElectricity™ Changes the Way We Live Transform Ordinary Surfaces into Electricity Generating Products Solar currently supplies 3% of the country’s electricity. It is expected to reach 20% by 2030 . By 2030, the sector would employ 600,000 people and add $345 billion to the national economy while offsetting carbon emissions by 35%. - Forbes Magazine, Nov. 2020 Good for the Environment Earth Abundant Raw Organic & Inorganic Materials; Lowest CO ₂ Footprint of All Solar Energy Transparent, Non - Intrusive Ultra - thin; Ultra - lightweight; Transparent; Electricity - Generating Coatings Ease of Manufacturing Low - Cost Materials; Solution Processable; Roll - To - Roll and Sheet - To - Sheet; High Throughput Manufacturing Wide Ranging Utility Generates Power from Sunlight, Shaded Low - light, and Artificial Lighting; Apply to Glass, Flexible Plastics, & Films SolarWindow coatings offer the highest power - to - weight ratio for Solar Energy solutions Page 9 John Rhee | February 2021
