Double layer antireflection coating design for conductive solar cells

摘要

In this study, we have demonstrated the efficiency improvement of a four-layer structure solar cell model based on conductive nanoparticle materials. New artificial conductive nanoparticles have been used to optimize the efficiency of solar cells and to overcome some limitations of the efficiency of conventional solar cells structures. The antireflection coating structure has been proposed where conductive nanoparticles (CNPs) film layer and TiO_(2) layer are sandwiched between a glass cover layer and a silicon substrate. The transmittance and reflectance are derived and computed by using the transfer matrix method and are obtained numerically for different values of unit cell sizes and gap widths of the CNPs. The nanoparticles dimensions have been adjusted leading to approximately 100% light transmission and the current density to be about 80 mA/cm~(2).
