CHEETAH innovation: 21% possible cost reduction for crystalline silicon PV

By: Mate Heisz, Business Analyst

A new report published by the EU funded CHEETAH project in January 2018 looked at CHEETAH's  innovations' cost impact on PV. More specifically, the CHEETAH project worked on high-level technology development in the field of:

  • Thin film CIGSe microconcentrator solar cells
  • Organic PV (OPV) solar cells with improved stability
  • Ultra-thin crystalline silicon (c-Si) solar cells and advanced processing steps

As for ultra-thin crystalline silicon, there is a potential cost reduction of 21 % when comparing benchmark wafer-based crystalline silicon photovoltaic modules to modules using epitaxially grown wafers of 120 μm thickness developed within the CHEETAH project. For this wafer thickness, only very minor adaptations in cell processing are required, if any at all, leaving the cost structure of that part as it is for standard cells.

To learn more about the cost impact of epitaxially grown wafers, thin film CIGSe microconcentrators and OPV solar cells with improved stability, download the CHEETAH report on the R&D impact on cost reduction here.

CHEETAH - Cost-reduction through material optimisation and higher energy output of solar photovoltaic modules - joining Europe's Research and Development efforts in support of its PV industry - was a 4 year combined collaborative project and coordination and support action funded under the European Commission's 7th Framework programme and ran between 2014 and 2017. The project consortium consisted of 34 partners from research institutes and universities.
