“…Only, when modeling the solar cell, it is necessary to take into account the effect of light. Ray Tracing [54], Transfer Matrix Method (TMM) [55] and Beam Propogation [56] methods are widely used for optical modeling of solar cells. In this paper, the optical modeling was performed using the TMM method.…”

This paper focuses on exploring new materials and structure as a means to increase the efficiency of solar cells. Since silicon is widespread on earth, it is desirable to study heterojunction solar cells made mainly of silicon and new materials. Therefore, ZnO/Si and TiO2/Si heterojunction solar cells were studied in this paper. First, the electrical and optical properties of ZnO and TiO2 were determined using the Perdew-Burke-Ernzerhof (PBE), PBE functional revised for solids (PBESol) and Perdew-Wang (PW91) functionals of the Generalized gradient approximation (GGA) in Density Functional Theory (DFT). The obtained results in various functionals are assessed and analyzed. It was found that geometric optimized structures of TiO2 and ZnO is mechanical stable. Accordingly, in all functionals, the effective mass of the electron in ZnO and TiO2 proved to be smaller than that of the hole. The mobility of electrons and holes in ZnO was calculated to be 430.72 cm 2 V -1 s -1 and 5.25 cm 2 V -1 s -1 respectively. In TiO2, it was 355.27 cm 2 V -1 s -1 and 46.38 cm 2 V -1 s -1 . When PW91, PBESol, PBE functionals were used, the dielectric constant was determined to be 11, 11.5, 8.5 for ZnO and 9.5, 10, 9 for TiO2, respectively. According to the DFT results, it was determined that ZnO and TiO2 are transparent and mainly n-type direct semiconductors. According to device simulation, the maximum short-circuit current of ZnO/Si and TiO2/Si heterojunction solar cells is 18 mA/cm 2 at a thickness of 80 nm and 15.3 mA/cm 2 at a thickness of 40 nm. Finally, the average fill factor of ZnO/Si and TiO2/Si solar cells was 0.73 and 0.76 respectively. So TiO2 can be used as a transparent contact and ZnO as an emitter layer in a silicon-based solar cell.

The most common method of harnessing solar energy is photovoltaic. With the revolution of new energy innovation in recent years, generation of electricity based on photovoltaic has possessed great progress, however, high cost is one of the primary issues encountered. In order to drive into a better manufacturing technology, the effectiveness of the cells and modules is opt for further cost reduction. The purpose of this research is to study the parameter on crystalline silicon solar cell with double layer of MgF₂/SiO₂ as its anti-reflective coating (ARC) which is the thickness. An antireflection coating mostly introduced in solar cell in order to reduce the reflection of light from the front surface of the cell and to enhance broadband of light absorption. Four Light trapping (LT) scheme with double layer of MgF₂/SiO₂ and adjusted thickness on 100 µm thin crystalline silicon(c-Si) was investigated. The optical properties within 300-1200 nm wavelength region were analyzed and from absorption curve, maximum potential photocurrent density (Jmax) for each LT schemes was calculated. With the addition of ARC into the c-Si, the Jmax increased up to 32.13 mA/cm2 and achieved 28.89 % enhancement compared to the Jmax of the c-Si reference (without ARC). Therefore, it is important to achieve optimum value in absorption that literally showed the excellent optical property of MgF₂/SiO₂ bilayer coatings.
