Transcript of "Wakonda Technologies - Clean Tech Kingpins"

  1. 1. High Efficiency Flexible Photovoltaics at Thin Film Costs Les Fritzemeier [email_address] (781) 460-2200, X201
  2. 2. Commodity PV Market Tightens <ul><li>Efficiency at low cost is key to survival in this market </li></ul>Rigid panel PV markets are significantly over served Silicon PV inventories are at historical highs… … and climbing!
  3. 3. While BIPV is underserved <ul><li>Residential and commercial rooftops … </li></ul><ul><li>“… a whole new addressable market” * </li></ul><ul><li>> $10B possible by 2015 with a cost effective, high efficiency, flexible, integrated PV roofing solution </li></ul>*Jane Palmieri, managing director Dow solar solutions
  4. 4. Wakonda Virtual Single Crystal (VSC) <ul><li>A low-cost flexible substrate </li></ul><ul><li>Crystalline semiconductor* growth </li></ul><ul><li>Conventional roll-to-roll processes </li></ul><ul><li>High performance photovoltaics , lighting and displays </li></ul>*VSC platform enables III-V, II-VI and Si semiconductor material growth
  5. 5. VSC Grain Size Drives Efficiency First Solar module NREL champion CdTe Optimized VSC cell “ Intrinsic” CdTe model NREL GaAs model Wakonda VSC A fundamentally different approach to flexible thin film PV <ul><li>Large, epitaxial grains on VSC foil: </li></ul><ul><li>Boost efficiency </li></ul><ul><li>Provide a more robust process window </li></ul><ul><li>Enable doping for multiple semiconductor materials </li></ul>
  6. 6. Cumulative Module Cost < $0.75/W p Wakonda Flexible Module at < 50 MW capacity $0.69/W p $0.49/W p 13% Efficiency 18% Efficiency Substrate Production Cell Fabrication Module Fabrication Market-leading flexible BIPV module at > $2.00/W p Wakonda BIPV Cost Advantage
  7. 7. Challenges and Outlook <ul><li>For Wakonda and other “hard materials” companies: </li></ul><ul><li>The critical challenge is to identify patient funding in the face of limited exit options </li></ul><ul><li>This, too, will pass </li></ul><ul><li>Expect to see accelerating clean tech materials company consolidation and innovative early stage financing </li></ul>
