“…The period of this structure is considered to be 300 nm. It should be noted that in the existing work, 25 the thickness of the silver layer was considered to be about 400 nm, which in our opinion, the choice of high thicknesses have no advantage and increases the fabrication cost. To investigate the effect of the thickness of the silver layer, we simulated the amount of the absorption of the silicon layer for different thicknesses of the silver layer (20, 60, 100, 200, 300, and 400 nm), which the results are shown in Figs.…”

“…First, by using the usual thicknesses mentioned in previous work, 25 we considered the simple solar cell (SSC) [Fig. 1(a)] consisting of a 100-nm-thick ITO layer as an anti-reflective layer and 400-nm-thick crystalline and amorphous silicon layers have been used as absorber layers in two different cases.…”

“…In addition, in previous works, optimizing the dimension of the gratings has been investigated in large scales, but in this work, we have made the scale small and more precise. These nanostructures increase the absorption in the absorber layer by increasing the reflected light path from the back surface of the cell and also due to the phenomenon of surface plasmon polariton (SPP) 25 . Surface plasmon resonance is the most interesting optical property of metallic nanostructures.…”

Thin film solar cells, which are the second generation of solar cells, have recently attracted much attention due to their low cost and abundance of fabrication materials. But due to the reduction in the thickness of the absorber layer in this generation to <0.5 μm, the amount of absorption is greatly reduced and the short circuit current density (J sh ) decreased due to the reduction of the light path length in the semiconductor. Therefore, light trapping is challenging in this generation to compensate for the reduced short circuit current. In this work, crystalline and amorphous silicon thin film solar cells, which are types of thin film solar cells have been investigated. In this study, using silver metal gratings with triangular and rectangular shapes on the back electrode of the solar cell, we investigated the effect of the grating structure on increasing absorption of the solar cell. Crystalline silicon (c-Si) and amorphous silicon (a-Si) have been used as absorber layer material due to their unique characteristics, such as low cost, abundance, and well established. The results show that by applying the optimal structure of grating in crystalline silicon solar cells, compared with the simple solar cell, the efficiency and short current of the cell increased from 8.87% and 16.81 (mA∕cm 2 ) to 13.34% and 24.78 (mA∕cm 2 ), respectively. And for the solar cell with amorphous silicon absorber layer, this increase in efficiency and short circuit current has reached from 14.75% and 28.74 (mA∕cm 2 ) to 15.22% and 29.6 (mA∕cm 2 ), respectively. This increase in electrical parameters of solar cells illustrates the positive effects of back grating structures in improvement of solar cell performance.

A modified design of the a‐Si thin film solar cell (TFSC) is presented. The c‐Si cap layer is introduced to increase the photon absorption and hence the enhanced photo carriers increase the overall short circuit current (Isc). Whereas, the highly doped a‐Si passivation layer reduces the minority carrier flow and recombination at the rear side of the cell and therefore the passivation layer is used to improve the open circuit voltage (Voc). The performance optimization and investigation of the cell characteristic is executed using the numerical simulation methodology. To further enhance the cell efficiency, the thickness and doping concentration of the c‐Si cap and a‐Si passivation layer is optimized. The improvement in absorption and passivation quality of the cell leads to the enhancement of 10.54% in current density (Jsc) and 71.51% improvement in the Voc respectively. The designed a‐Si TFSC absorbs the incoming solar spectrum from 300nm to 850nm of wavelength and rest of the spectrum is transmitted. The External and Internal quantum efficiency (EQE and IQE) of the cell is well over 95%. The optimized efficiency of 15.33% is obtained for the designed cap layered a‐Si passivated cell in AM1.5G environment using Ray tracing methodology.This article is protected by copyright.
