Abstract
The influence of sintering temperatures on solution-processed cadmium telluride (CdTe) nanocrystal films is studied in order to maximize the performance of CdTe/Al Schottky nanocrystal solar cells. The best overall performance of 2.67% efficiency at air mass 1.5 was achieved from devices with CdTe films sintered at 350 ℃ X-ray diffraction, scanning electron microscopy and UV-vis absorption measurements show that the CdTe nanocrystal grains began to grow remarkably well when sintering temperatures increased to 350 ℃. By analyzing the current-voltage characteristics, we find that the short-circuit current densities of devices increase with sintering temperatures ranging from 200 to 400 ℃, but, the over-sintered (450 ℃) treatment induces the shunting of devices.-
