Description
The materials used in this work were regent grade of lanthanum chloride (LaCl3 .7H2O) and
aluminium chloride (AlCl3 . 6H2O). The lanthanum aluninate (La1-xAlxO3: x = 0.02 mol) clear
solution was firstly performed by adding appropriate amount of (NH4OH) into the mixture
solution. Lanthanum aluminate sol-gel was refluxed with oil–bath at 110˚C for 3hr. Lanthanum
aluminate (LAO2) thin film was formed on defect-free p-Si (100) substrate by spin coating
technique. To change the coating layer into oxide film, they were sintered at 400˚C to 600˚C in
open atmosphere. X-ray Diffraction Analysis (XRD) and Scanning Electron Microscopy
(SEM) measurement were made to examine the film morphology and microstructural
properties. As a result of XRD investigation, the observed peaks were matched with those of
standard library file. Film thickness was obtained by cross-sectional SEM images. 1/C2-V
characteristics were also observed for film qualification. I-V characteristics were measured
under illumination by sodium lamp. The best power conversion efficiency of 10.65%
photovoltaic cell with the LAO2 layer annealed at 500 °C showed a short-circuit current (Isc) of
1.22 x 10-5 A, an open-circuit voltage (Voc) of 3.19V and a fill factor (Ff) of 0.39 under
illumination by sodium lamp.
