| Popis: | Thin film solar cells are preferable to the researchers and in applications due to the minimum material usage and to the rising of their efficiencies. In particular, thin film solar cells, which are designed based one transition metal chalcogenide materials, paly an essential role in solar energy conversion market. In this paper, transition metals with chalcogenide Nickel selenide termed as (NiSe2/Si) are synthesized. To this end, polycrystalline NiSe2 thin films are deposited through the use of vacuum evaporation technique under vacuum of 2.1x10-5 mbar, which are supplied to different annealing temperatures. The results show that under an annealed temperature of 525 K, the nickel sulfoselenide thin films are polycrystalline with an efficient regularity and best crystalline quality. In addition, the results demonstrate that the intersection argument for the optical properties under investigation provid the direct bandgap, over which the films have inferred on variety (1.55 and 1.75 eV). Overall, the results illustrate that an efficiency of 2.89% can be achieved with 525 K temperature. |
