SUMMARY
We use chemical vapor deposition for synthesisizing nano composites. With vapprized precousrs, the nucleation and growth happen under high temperature with chemical reaction and thus diffusion on top of silicon wafer. We focus on (1) changing relative location for changing nucleation density. Moreover, we apply extra design of heating curve for understanding the growth procedure. (2) as grown sample were mechanically transferred on top of TiO2 and followed by optical and electrical properties characterization. The final part is discussion of solar cell performance. Next is to characterize as grown samples and as fabricated cells. Iinstruments which were applied include: (1) Morphology: Optical microscopy, Scanning electron microscopy, Transmission electron microscopy. (2) Photovoltatic properties: Photoluminescence spectrometer, Ultraviolet-Visible Spectrophotometer, Atomic force microscope, Four point probe. (3) Physical and chemical properties: Raman spectrometer. (4) Material crystallinity: X-ray diffraction meter, TEM.
With the OM images and Raman spectrums, we observe that the MoS2 grown from distribution of isolated islands to continuous film by adjusting nucleation density and precursor concentration. Moreover, the single crystal MoO2 nanorod is synthesisized with higher reactant concentration and various cooling condition. After characterizing counductivity and surface work function by four point probe and KPFM. We pick the sample with lowest work function and hghest counductivity for solar cell calibration. The referencre cells were pick with different parameters. We found that the sample with lowest work function and highest counductivity shows the best efficiency (10%).
