- Abstract
- For CiGS, the high-level research aim of absCIGS is twofold, First, it aims at the development of a lab-scale non-vacuum baseline process for the formation of CIGS absorber layers, leading to cells with a conversion efficiency of 15%. Second, this work is complemented by the scientific understanding of the different steps in the process, running from the formation of the CIGS precursors to the film transformation process. To achieve this, absCIGS sets great store by obtaining full control over the input/output relations, where the input is a dispersion of precursor nanoparticles(NPs) and the output is a dense CIGS TF. This control is achieved in three different ways. 1. Combining the full characterization of the precursor NPs in terms of size, shape, composition, crystal structure and importantly, surface chemistry with the in-situ monitoring of the transformation of a precursor NP film into a dense CIGS TF. 2. Installing a dedictated wet bench with home-built reactors to ensure reproducible processing results that can be transferred to other setups. 3. Initiating a modelling effort leading to an understanding of the film transformation process.
