英文摘要	CdTe nanocrystal (NC)/CdS p-n hetero-junction solar cells with an ITO/ZnO-In/CdS/CdTe/MoOx/Ag-inverted structure were prepared by using a layer-by-layer solution process. The CdS thin films were prepared by chemical bath deposition on top of ITO/ZnO-In and were found to be very compact and pin-hole free in a large area, which insured high quality CdTe NCs thin-film formation upon it. The device performance was strongly related to the CdCl2 annealing temperature and annealing time. Devices exhibited power conversion efficiency (PCE) of 3.08 % following 400 degrees C CdCl2 annealing for 5 min, which was a good efficiency for solution processed CdTe/CdS NC-inverted solar cells. By carefully designing and optimizing the CdCl2-annealing conditions (370 degrees C CdCl2 annealing for about 15 min), the PCE of such devices showed a 21 % increase, in comparison to 400 degrees C CdCl2-annealing conditions, and reached a better PCE of 3.73 % while keeping a relatively high V-OC of 0.49 V. This PCE value, to the best of our knowledge, is the highest PCE reported for solution processed CdTe-CdS NC solar cells. Moreover, the inverted solar cell device was very stable when kept under ambient conditions, less than 4 % degradation was observed in PCE after 40 days storage.
