Realization of high efficiency micromorph tandem silicon solar cells on glass and plastic substrates: Issues and potential

Christophe Ballif, Franz-Josef Haug, Matthieu Despeisse, Mathieu Gérard Boccard, Sylvain Nicolay, Andrea Feltrin, Peter Cuony, Martin Python

High conversion efficiency for (amorphous/microcrystalline) "micromorph" tandem solar cells requires both a dedicated light management, to keep the absorber layers as thin as possible, and optimized growth conditions of the microcrystalline silicon (μc-Si: ...

Enhancement of microcrystalline n-i-p solar cell performance via use of pre-covering layers and H-2 treatment

Christophe Ballif, Franz-Josef Haug, Xavier Niquille, Vanessa Terrazzoni-Daudrix

We study the effects of a-Si:H and mu c-Si:H covering layers and an H-2 treatment on the characteristics of mu c-Si:H thin film solar cells deposited in open single chamber very high frequency plasma enhanced chemical vapor deposition systems. Secondary io ...

Strategies to Optimizing Dye-Sensitized Solar Cells

Sophie Wenger

Dye-sensitized solar cells (DSCs) constitute a novel class of hybrid organic-inorganic solar cells. At the heart of the device is a mesoporous film of titanium dioxide (TiO2) nanoparticles, which are coated with a monolayer of dye sensitive to the visible ...

Modelling of light scattering from micro- and nanotextured surfaces

Christophe Ballif, Franz-Josef Haug, Corsin Battaglia

We present a calculation routine for the angular and spectral dependence of scattered light after transmission through textured interfaces. Based on a modified Rayleigh–Sommerfeld integral, the treatment requires only measured surface profiles, and the ref ...
