Within our team »Diagnostics and Metrology« we are currently offering a topic for master thesis »Sun Simulators and Solar-to-Hydrogen Conversion Efficiency in Photo-Electrochemical Water Splitting Cells«.
A LED sun simulator shall be integrated with a reactor device for photo-electrochemical water splitting in order to determine spectrally resolved solar-to-hydrogen conversion efficiency.
Motivation and Background:
Intermittent solar energy is creating an inherent mismatch between photovoltaic (PV) energy production and consumption. Photo-electrochemical (PEC) water-splitting is an alternative that has the potential to realize affordable solar fuels by converting solar energy into a storable power source, such as hydrogen.
PEC solar cells and modules will be rated technologically as well as economically based on their solar-to-hydrogen (STH) conversion efficiency. Reproducible and quantitative STH metrology solutions require standardized sun simulator irradiation, reproducible electro-chemical conditions and precise characterization according to Faraday’s law for Hydrogen production. LED sun simulators for advanced STH performance analysis provide additional information on the spectral conversion efficiency.
Within the scope of this master thesis an LED sun simulator based STH metrology setup shall be configured and launched. Performance tests have to be implemented with various PEC solar cells with regard to quantitative and reliable metrology operation.
- Configuration and implementation of STH metrology setup for PEC solar cells
- Methodology for quantitative and reproducible STH measurements
- Advanced spectral measurements based on LED sun simulators
