Abstract
This paper studies the different surface grating shape and their effects on the optical, electrical properties and efficiency of thin film solar cell model. The semiconductor transport model is applied for solving the electrical properties, whereas the optical effect was added using electromagnetic modeling. The efficiency of the model using triangle grating was 12.24% and in the model without grating was 7.75%. The PV efficiency was improved by 4.51% in case of triangle grating. The maximum power observed in triangle grating is 12.5 [mW] that makes difference with [5 mW] than without grating model, and also the current density is 12.5 [mA/cm2]. The absorbance coefficient of the two models enhanced by 20% increase on photon absorbance in the modeled solar cell.
