C-330 Introduction to Thin Film Photovoltaic Technologies (half day)

This course focuses on PV thin film technologies like Cu(In,Ga)(Se,S)2, CdTe an the amorphous and microcrystalline silicon solar cells which are nowadays mainly introduced. Starting point is a market overview followed by the basic designs of these solar cell types and their efficiency potentials. Especially the different manufacturing technologies are introduced focusing the different production and process steps of each solar cell type.

Topical Outline:

  • Market situation
  • Cell design of thin film solar cells
  • Research activities
  • Production and process technologies for thin film solar cells
