Hot carrier solar cell (HCSC): A new generation nano-structured solar cell

With the global demand for renewable energy sources, there is a race in the scientific community to build a highly efficient solar cell. Nanostructured solar cells are a class of photovoltaic devices which is a strong candidate for high efficiency energy generation. Hot carrier solar cells are a kind of nanostructured solar cells, for offering high power conversion efficiency, compared with the conventional single absorber solar cell, through the process of extracting power from photo-generated high energetic carriers prior to thermalization to lattice via phonons. In this paper, we have analyzed the band structure, thermodynamic properties, and hot carrier transport in solar cell.
