Forward Looking Statements

2

This presentation contains certain forward looking statements relating to the company’s financial results, business prospects and the development and commercialization of the company’s solar

  • technology. These statements are based on management’s current expectations and beliefs and

are subject to a number of factors which involve known and unknown risks, delays, uncertainties and other factors not under the company’s control which may cause actual results, performance

  • r achievements of the company to be materially different from the results, performance or
  • ther expectations implied by these forward looking statements.

In any forward looking statement in which Natcore Technology Inc. expresses an expectation or belief as to future results, such expectations or beliefs are expressed in good faith and are believed to have a reasonable basis, but there can be no assurance that the statement or expectation or belief will be achieved. These factors include risks associated with intellectual property protection, financial projections, market projections and other factors detailed in the company’s filings with SEDAR. Natcore does not undertake an obligation to update the forward looking statements, except as required by applicable laws.

  • Currently hold the world record for silicon

(>25%)

  • Will always be advantaged due to lack of

Cost: Foils & Laminates

Minimized Material Cost

  • Current cells use about

190mg of Ag per cell:

  • Raw metal cost: ~10¢/cell
  • Replaced with ~1.5g Al:
  • Raw metal cost ~ 0.2¢/cell
  • Planning to work with NREL

for accurate cost model

Leveraging an existing industry

  • Worldwide Aluminum foil

production: ~100,000M m2 per year

  • The entire solar industry:

Requires ~400M m2

  • Low cost driven by existing

high volume
