Typical silicon-based solar cells have limitation on conversion efficiencies especially at IR wavelengths. Utilization of IR spectra and thermal parts is critical to increase the total efficiency of the solar cells. In this research, a hybrid photovoltaic/thermoelectric conversion system was proposed to maximize conversion efficiencies. Samco ICP-RIE System, RIE-101iPH was used to form black silicon (b-Si) on a silicon substrate.
