While decreasing the thickness of active layers is important in reducing the cost of solar cells, the absorption of incident light is challenging as the thickness becomes smaller than the wavelength. Metal nano-structures can be used on the top or bottom of the active layers to couple light of different plasmonic and photonic modes. Metal nano-structures can also be used as an intermediate layer within an active layer or between two active layers as in tandem solar cells. In this work, we discuss two photovoltaic cells based on plasmonic-inspired designs—one with silicon strips on the top and grooves on the silver back contact layer and the other with a periodically perforated metal layer in-between the two active layers.
