Wakonda Technologies - Clean Tech Kingpins

High Efficiency Flexible Photovoltaics at Thin Film Costs Les Fritzemeier [email_address] (781) 460-2200, X201

Commodity PV Market Tightens
Efficiency at low cost is key to survival in this market
Rigid panel PV markets are significantly over served Silicon PV inventories are at historical highs… … and climbing!

While BIPV is underserved
Residential and commercial rooftops …
“… a whole new addressable market” *
> $10B possible by 2015 with a cost effective, high efficiency, flexible, integrated PV roofing solution
*Jane Palmieri, managing director Dow solar solutions

Wakonda Virtual Single Crystal (VSC)
A low-cost flexible substrate
Crystalline semiconductor* growth
Conventional roll-to-roll processes
High performance photovoltaics , lighting and displays
*VSC platform enables III-V, II-VI and Si semiconductor material growth

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
Large, epitaxial grains on VSC foil:
Boost efficiency
Provide a more robust process window
Enable doping for multiple semiconductor materials

Challenges and Outlook
For Wakonda and other “hard materials” companies:
The critical challenge is to identify patient funding in the face of limited exit options
This, too, will pass
Expect to see accelerating clean tech materials company consolidation and innovative early stage financing
