Abstract
To design advanced solar cells with high performance, both the surface and interface structures of multimaterials
are key issues. The surface structure on materials might be produced by the interaction with
short laser pulses. The recent remarkable developments of femtosecond laser technologies are opening
new aspects in the physics of laser-matter interactions and laser applications. These phenomena are
especially distinguished in laser material interactions, which are never seen in nanosecond laser
interactions. For femtosecond laser ablation, we observed an extremely small amount of ablation (less
than a nanometer depth) even with a rather low laser fluence, resulting in discriminative morphology in/
on the material surface. To consider surface structuring on materials, we reviewed the recent progress of
solar cells controlled by the surface and interface structures of multi-materials.
