New MAterials for Tandem Solar cells (MATS)

About the project

The main goal of MATS is to investigate fundamental properties and photovoltaic diodes based on ZnO_xN_y thin films. These diodes are optimized for use as a top cell in a silicon-based tandem solar cell.

Methods

Depostion optimization

Optimal deposition parameters for both undoped and doped ZnOn thin films are studied using RF, DC and HiPIMS magnetron sputtering. The aim is to produce samples with high mobility, carrier concentrations low enough for non-abrupt pn junctions and an optical bandgap of 1.7eV.
Realizing and optimizing of ZnON pn-junctions, using both Si and higher bandgap-materials.

Characterization

Structural, chemical, optical and electrical characterization are utilized to understand both macroscopic and microscopic processes. These include, but are not limited to Hall, XRD, IV, CV, DLTS, TAS, EDS, UV-NIR-VIS.

Simulation

Simulate the effect of various film parameters and various emitter options on overall solar cell performance and understand underlying physical processes.

Financing

The project is financed by the Research Council of Norway through the Frinatek program. (no. 288596).
