Hybrid solar cells have gained much attention because of their simple mechanism and low cost as compared to the conventional p-n Si solar cells. We fabricated hybrid solar cells using micro(nano) patterned n-Si substrates. The patterns were formed using nanoimprint lithography and a simple metal-assisted chemical etching method. Owing to the increased light absorption and superior carrier collection...
Hierarchical Al surfaces were fabricated using three different kinds of alkaline-based chemical etching processes. The surface morphology changes to a needle-like microstructure or to nanoscale flakes on a microscale porous structure depending on the chemical solution used. These surfaces were characterized by field-emission scanning electron microscopy, X-ray diffraction analysis, X-ray photoelectron...
