Abstract
In this paper, we discuss a new method for increasing the efficiency of cadmium telluride (CdTe) thin film solar cells (changing frequency in pulsed laser and knowing its effect on solar cells); using the pulse laser (power 800[Formula: see text]mJ), solar cells with (Al/Si/[Formula: see text]-Psi/CdTe/Al) structure were formed using the vacuum deposition method for three samples at various frequencies (4, 5, 6)[Formula: see text]Hz. X-ray diffraction was used to examine nanostructures ([Formula: see text]-Psi, CdTe) for structural, optical and morphological features, UV-Vis spectrophotometers and microscopy of atomic forces. The calculated thin film (CdTe) optical energy value was 2.15, 2.25 and 2.45[Formula: see text]eV accordingly. The test results showed that the solar cell’s highest energy conversion efficiency (PCE) was 2.73, 3.42 and 4.28%; this study reveals and examines the effective hybrid Perovskite solar cells based on porous silicone. With an increase in the frequency of pulsed laser, the efficiency of the prepared solar cells increased.
