Scattering parameter analysis of different transparent conductive thin films element on silicon solar cell

This paper presents the performance of scattering parameters from different types of transparent conductive thin film. In this study, four types of optically conductive thin film i.e. AgHT-4, AgHT-8, ITO, and Kapton film have been investigated. Each film was designed with triangular loop shape and positioned on top of cover glass of solar panel and grounded RT/Duroid 5880 substrate. The element was designed to operate at Ku-band frequency range. Simulation results from the CST microwave studio showed that element of Kapton film exhibits the best scattering parameter performance. The bandwidth can achieve 15.2%, while the linear phase range reaches 361°. It also demonstrated that the dual frequency operational element contributes the lowest phase slope value of around 0.063°/μm.
