Outline
  • Thin Film and Global Solar Insolation
  • Amorphous Silicon Thin Film Advantages
  • Moser Baers Thin Film Plan
  • Summary

3
Global Solar Insolation
  • Solar insolation is dependent on geographies
  • Dependent upon the
  • geography the radiation
  • has direct and diffuse
  • light components
  • Ambient temperature
  • is location dependent
  • Slight difference in
  • spectral components
  • from place to place
  • Response of solar cell dependent on all above
    components

PV Technologies Geography
  • Single technology
  • is not suitable for
  • all geographies.
  • Technology choice
  • dependent on solar
  • insolation and temperature
  • Market transitioning from
  • /W to /kWh.
  • High efficiency modules do
  • not always give the lowest
  • delivered energy cost(/kWh).

Thin Film PV Advantages
  • Tremendous cost reduction potential
  • Automated module manufacturing
  • Employs less material and
  • capacity growth not dependent
  • on silicon paucity
  • Temperature coefficient for
  • power reduction is lower than
  • crystalline silicon for all thin
  • film modules
  • Performance in the low light condition
  • and partial shading.

Amorphous Si The Technology of Choice
  • Abundant availability of environmental friendly
    raw materials
  • Commercial availability of
  • reliable manufacturing equipment
  • Managable scale-up issues
  • Potential to reduce cost by
  • supply chain and efficiency
  • improvement.
  • Lowest temperature coefficient of
  • power reduction among thin films
  • Provides product flexibility like
  • BIPV modules

Capacity Ramp Up
  • Tool successfully installed
  • Trial runs successful
  • Production start-up July08
  • Technical and
  • operational staff with
  • experience of running
  • thin film PV plant in place
  • Thin film expertise of
  • optical media being
  • leveraged in sputtering
  • of reflector layer

Economies of Scale
  • Strategic Tie-up
  • with glass manufacturer
  • Optimum utilization
  • of gases
  • Volume purchase
  • Simplified junction
  • box and wires
  • Economies of scale

Summary
  • Thin film PV has tremendous cost down potential
    - blend of
  • equipment reliability and process technology.
  • Thin film has an advantage in certain geographic
    locations in
  • terms of delivered energy cost due to better
    performance
  • at higher temperatures and diffused light
    conditions
  • Amorphous silicon is promising because
  • Availability of reliable equipment which has
    been proven in
  • display industry.
  • Supply of raw materials and non-existent
    environment issues.
  • Potential to improve efficiency further and
    hence cost down.
  • Moser Baers experience in thin film as well as
    managing large
  • scale manufacturing operations will be
    leveraged to reduce
  • cost by technological innovation, supply
    chain and logistics.
