Data_Sheet_1_Effect of Cd1-xMnxSe Alloy Thickness on the Optical and Photovoltaic Properties of Quantum Dot-Sensitized Solar Cells.xlsx

In this work, the Cd_1−xMn_xSe alloy was successfully prepared using a successive ionic layer adsorption and reaction method to investigate the layers' effect on the properties of devices while concentration dopant was optimized at 20% (molar concentrations between Mn²⁺ and Cd²⁺ ions in the Cd_1−xMn_xSe material). The layers of the Cd_1−xMn_xSe alloy play a role in improving the optical, photovoltaic, and electrochemical properties of the solar cells. Hence, the efficiency performance of devices based on the Cd_1−xMn_xSe alloy reached ~3.8%. Besides, in order to explain this result, the experimental I–V curve was also used to determine the resistances at the interfaces and the resistance diffusion of the devices. This dynamic resistance can be compared with that of electrochemical impedance spectra.
