Thermoelectric and Photovoltaic Properties of Mn-Doped Kesterite CuZnMnSnSe.

The semiconductor CuZnSnSe (CZTSe) is a promising candidate for both thermoelectric and photovoltaic energy harvesting applications due to a combination of features such as direct band gap, high absorption coefficient, and low thermal conductivity. We report the solid-state synthesis and characterization of Mn-doped CuZnMnSnSe ( = 0, 0.05, 0.
