Abstract:

In this paper, a new design methodology by optimizing the silicon/organic interface morphology is proposed to achieve superior optical behavior for pentacene-based organic/inorganic solar cells. Our purpose dwells on reducing the refracting light in the silicon and improves the absorbance behavior in the solar cell. In this context, a numerical model based on accurate solutions of Maxwell’s equations is developed in order to study the impact of both interface texturization morphologies (triangular and grooves) on the optical absorbance and electrical performance. It is found that the proposed design morphology has profound implication on modulating the electric field, which increases the light trapping capability. It is also confirmed that the overall electrical performance is significantly improved as compared to the conventional organic/inorganic solar cells, where the proposed design exhibits superior integral absorption behavior and large interface area. Moreover, a new hybrid approach by combining of the numerical and metaheuristic models is developed to boost the device performance by optimizing the interface morphology. The obtained results make the proposed design methodology valuable for providing high-efficiency organic/inorganic solar cells.
