摘要

Electronic transport mechanisms in Sb ₂ Se ₃ thin-film solar cells were investigated using temperature-dependent current-voltage (J-V) measurements. Sb ₂ Se ₃ thin films were deposited via the vapor transporting deposition method using a double-temperature-zone tubular furnace system, and comparative studies were performed for Sb ₂ Se ₃ films formed on substrates located at three different positions away from the furnace center. The device efficiency varied from 3.83 to 6.24%. First, structural properties obtained by X-ray diffraction, Raman and scanning electron microscopy measurements verified the optimal Sb ₂ Se ₃ film quality for the cell with the highest efficiency. Then, temperature-dependent saturation current and open-circuit voltage (V _oc ) measurements revealed that the dominant carrier recombination occurred in the CdS/Sb ₂ Se ₃ interface region, which possibly influenced the V _oc for all cells: the highest V _oc for the optimal Sb ₂ Se ₃ cell was at least partly due to it having the lowest CdS/Sb ₂ Se ₃ interface recombination rate. Finally, the reverse bias current relationship revealed that non-ohmic shunt current (space-charge-limited current, SCLC) plays an important role in affecting the performance of solar cells, as lower-efficiency cells had higher non-ohmic shunt current.
