Tandem solar cell

A fabrication technique using Al2O3-passivated local contacts was employed to produce narrow-bandgap CuInSe2 (CISe) photoabsorbers, which are well-suited as bottom cell materials in tandem devices. In this study, for the first time, we attempted to improve the photovoltaic conversion efficiency (PCE) of CISe solar cells by adding a Al2O3 passivation layer.

This study demonstrates correlations between element diffusion behavior and notch-point formation in ACIGS films, which ultimately influence the resulting current circuit voltage and fill factor. Our findings delineate a novel approach for fabricating a suitably tailored band gap grading in ACIGS, which serves as a bottom subcell in tandem configuration.

In this work, we perform a detailed balance analysis of the maximum conversion efficiency of solar cells made from III-nitride materials. First, we present an analysis of single junction solar cells made from InxGa1
xN alloys, and next we focus on tandem cells made from III-nitride and silicon materials.

Aeberhard Nanoscale Research Letters 2011, 6:242 http://www.nanoscalereslett.com/content/6/1/242 NANO EXPRESS Open Access Theory and simulation of photogeneration and transport in Si-SiOx superlattice absorbers Urs Aeberhard Abstract Si-SiOx superlattices are among the candidates that have been proposed as high band gap absorber material in allSi tandem solar cell devices. Owing to the large potential barriers for photoexited charge carriers, transport in these devices is restricted to quantum-confined superlattice states.
