Transparent thin film materials have unique characteristics when used in the manufacture of solar cells. Transparent thin film materials will transmit some of the photon energy and reflect less. In order to maximize energy absorption in solar cells so that the energy transmitted by the thin film material is not wasted, it can be stacked with solar cells from other materials whose absorption spectrum is different from the absorption of the thin film material. By knowing the optical and electrical characteristics of each material, it is expected to determine the pairing of thin film materials with other materials. In this study, optical simulations will be carried out using the Lumerical FDTD simulator. By using this simulator, the reflection, transmission, and absorption spectra of a material can be determined. This simulation was carried out on several materials including Crystalline Si, GaAs, InAs, GaAs-InAs, CdTe, CdSe, and Perovskite. Several of these materials will be simulated at thicknesses of 2.0 ?m, 1.5 ?m, 1.0 ?m, 0.5 ?m, 0.1 ?m, and 50 nm. The thicker the material used, the greater the absorption power obtained and the greater the short-circuit current. Each material has a different absorption spectrum for each wavelength. There are materials that have good absorption at low wavelengths, some are good at high wavelengths. By stacking two solar cell materials by positioning the transparent material on top of the other, an increase in power will be obtained if the spectra of the two solar cell materials complement each other. Testing was carried out by simulating two Lumerical FDTD materials, and measuring and calculating power using colored transparent acrylic as an approach to transparent thin film solar cells. Each color on acrylic has an absorption spectrum for each wavelength. there is a decrease in power generated by the solar cell due to the compaction of acrylic on top of the solar panel. In the end, a selection of the most optimal combination of two materials in spectrum absorption was made. The combination of two materials that had the largest total absorption was a combination of perovskite material with GaAs-InAs with a total absorption of 82.16%.
