Microstructure Analysis of Current‐Fired Contacts on TOPCon Layers Open
We report on the analysis of the microstructure of a current‐fired contact formed by screen printing, drying, and sintering of a silver paste and subsequent laser‐enhanced contact optimization (LECO) for silicon solar cells with tunnel‐oxi…

Extracting contact recombination from FFT-filtered photoluminescence imaging of half-metallised silicon solar cells Open
Recombination at the metal-silicon interface is a major barrier to reaching the theoretical power conversion efficiency limits. We present a PL method for evaluating the metal contact recombination current ( J 0,c ) of rear TOPCon metallis…

On the Robustness of the Determination of Metal‐Induced Recombination from Photoluminescence Images on Solar Cells Open
The robustness of a recently developed method to obtain the recombination current–density ( J 0,met ) under the front metallization fingers of silicon solar cells is investigated. This method requires a voltage‐calibrated photoluminescence…

Custom plating of nanoscale semiconductor/catalyst junctions for photoelectrochemical water splitting Open
Templated nanoelectrodeposition on photoactive n-Si is introduced here for the customization of nanoscale inhomogeneous Schottky junctions. We demonstrate the use of these surfaces as photoanodes for water dissociation.

Understanding and monitoring the capacitance‐voltage technique for the characterization of tandem solar cells Open
This paper presents a simple and nondestructive method to determine doping densities and built‐in potential of subcells by adapting the well‐known capacitance‐voltage ( C ‐ V ) technique to two‐terminal (2 T) tandem solar cells. Because of…

Electrical characterization of low temperature plasma epitaxial Si grown on highly doped Si substrates Open
Epitaxial silicon layers were grown on highly doped c-Si substrates using the plasma-enhanced chemical vapour deposition process (PECVD) at low temperature (175 °C). The transport and defect-related properties of these epi-Si layers were c…
