This document provides an overview of Ascent Solar Technologies and opportunities for flexible solar power in emerging markets and off-grid applications. Ascent is transitioning from development to commercial production of thin-film CIGS solar modules using roll-to-roll manufacturing and monolithic integration. Their largest module is world's largest monolithic flexible product. Off-grid applications such as consumer power and transportation are key markets as solar achieves parity with traditional energy sources in terms of life cycle cost over time. Over 1.5 billion people worldwide currently lack access to electricity, representing a substantial off-grid market opportunity.

2. Forward Looking Statements In addition to historical information, this presentation contains forward–looking statements that are based on assumptions made by management regarding future circumstances over which the company may have little or no control and involve risks, uncertainties and other factors that may cause actual results to be materially different from any future results expressed or implied by such forward–looking statements. These factors include, among others, the following: general economic and business conditions; the company’s cost of operations; the success of cost containment initiatives, including costs arising from changes in regulations; availability and cost of capital; the success of growth initiatives; the effect of regulation on consolidation of the industry; the ability to generate earnings from capital investment; and those risks and uncertainties described in the Risk Factors section of the Company’s Form 10-K filed with the SEC for the year ended 12/31/09. The Company is not obligated to update its forward–looking statements to reflect the impact of future events.

20. What is Parity? Evolving Value Propositions Traditional Energy Sources Life Cycle Cost Solar Solution Over Time The Life Cycle Cost of Solar Solutions has improved over time and are now directly competitive with Traditional Energy Sources in various applications

21. Off-Grid Applications Reductions in PV manufacturing cost Economies of scale Improvements in efficiency Increasing cost of alternatives Diesel fuel (generators) Societal concerns Public health (indoor air quality) Decreasing power requirements Energy efficiency improvements due to related technologies (LEDS) Grid-Connected Projects Reductions in PV manufacturing cost Economies of scale Improvements in efficiency Increasing cost of alternatives Carbon Pricing Societal concerns Environmental (Fukushima) Market Incentives Decreasing subsidy levels in a number of primary markets Parity: Drivers and Enablers Grid-Connected markets are still subsidy dependent. Recently, governments have reduced incentive levels in primary markets creating significant demand uncertainty.
