Anti reflection coating (ARC) is used in solar cell that functions to increase the quantity of light absorption. To obtain maximum results would require a good combination between ARC’s materials and the synthesis technique. TiO2-SiO2 was used as ARC materials because it has good passivity and high refractive index value. Pulsed Laser Deposition (PLD) method was used for synthesis technique because it has high photon energy and high temperature. Characterization are done by using Field Effect Scanning Electron Microscope (FESEM), X-Ray Diffraction (XRD), and Ultraviolet-Visible (UV-Vis) Spectrophotometry. The best result, anti reflection coating TiO2-SiO2 successfully reduced the reflection value from 35.69% to 14.11% for silicon substrate. It was gained with the properties of laser’s wavelength at 532 nm, laser’s energy at 100 mJ, and deposition time at 20 seconds.
We reported the fabrication of 1D photonic crystal structure and investigated its application for tuning colloidal CdSe
quantum dot emission. The photonic crystals was made by using sol-gel method and consists of TiO2 and SiO2
multilayers on glass substrate. The colloidal quantum dot is CdSe quantum dot with emission wavelength around 630
nm, which is similar to photonic band gap of fabricated photonic crystals. The quantum dot was dropped and dried on the
opposite side of photonic crystals. We measured angle dependence of transmission of photonic crystal and angle
dependence photoluminescence of quantum dot emission. We found that quantum dot emission was influenced by
excitation angle ; therefore photonic crystals can be useful for tuning the emission of quantum dot. We have confirmed
that the angle dependence photoluminescence of quantum dot is significantly related to photonic band gap of photonic
crystal. This work leads to future application of photonic crystal on quantum dot emission such as quantum dot lasing.
