Solution Processed All-Inorganic Solar Cells Using CdTe Quantum Dots and Tetrapods |
| 초록 |
CdTe thin film solar cells have drawn strong interest in industry due to its simplicity in chemical composition with proper bandgap along with high absorption coefficient and power conversion efficiency. However, conventional processes to realize CdTe thin films requires long fabrication time and energy consumption, thus increasing production cost. In this presentation, we demonstrate CdTe solar cells using shape-controlled CdTe nanocrystal inks for economic solution processing. To form large and directional CdTe grains, we employed binary CdTe nanocrystal inks that contain both spherical and tetrapod-shaped nanocrystals and sinter the blend film at elevated temperature. The influence of sintering temperature, blending ratio, and the size of nanocrystals on the growth of CdTe grains were examined by UV-visible absorption spectroscopy, X-ray diffraction, and scanning electron microscopy. We also investigated the relationship between grain size/orientation and solar cell performance. |
