Abstract
In the first phase of this study, a layer of cadmium sulphide (CdS) and a layer of aluminium gallium nitride (Al0.1GaN0.9) was deposited on a silicon substrate (10% AlN with 70% GaN) was deposited on a silicon substrate by using a pulse laser deposition system (PLD). The physical properties of the prepared films of Al0.1GaN0.9 and CdS were studied. Photoluminescence (PL) spectra revealed emission peaks at 471 nm for the CdS layer and 339 nm for AlGaN. The energy bandgap of the CdS layer was 2.63 eV, while the bandgaps of the AlGaN samples were 3.66 eV. The I-V curve measurements of Al0.1GaN0.9 showed that barrier height (ΦB) 0.57 eV, while the electron affinity values 4.63 eV. In the second phase of this study, the results of the experimental study in the computer simulation were used to study the effect of the back contact work function on the performance of AlGaN/CdS/Si solar cell. The study also revealed that the increase the back metal work function improved Jsc and Voc values, enhancing efficiency. The efficiency of the solar cells significantly increased, reaching 18.92% at a metal work function of ≈5.2 eV.
