What is a Schottky junction based solar-cell?
Solar-cells based on Schottky junctions between metals and semiconductors (without or with an intermediate insulator) are among the main possibilities towards economical photovoltaic conversion of the solar energy. This is mainly due to their structural simplicity and hence the ease of their realization.
What is Schottky-junction in solar cells?
The Schottky-junction is an attempt to increase the efficiency of solar cells by introducing an impurity energy level in the band gap. This impurity can absorb more lower energy photons, which improves the power conversion efficiency of the cell.
