“…The calculation of a carrier generation profile was performed using Equation (A4) from Appendix A . Absorbance was obtained:

, where reflectance was taken from Maryam Valiei et al [ 23 ]. This was the case, as silicon cells are already very well developed in the industry, and it is not possible to obtain good light trapping without the presence of the texture and precise replication of the cell’s structure; Only the SRH recombination was considered in this work (Auger and band-to-band were not); In addition, it should be noted that alternatively, MoO 3 can be used as a tunnel junction for such a tandem device that also creates a blocking layer for atom diffusion during the sulfurization/selenization at 450–550 °C of the top sub cell.…”

Recently, the development of tandem devices has become one of the main strategies for further improving the efficiency of photovoltaic modules. In this regard, combining well-established Si technology with thin film technology is one of the most promising approaches. However, this imposes several limitations on such thin film technology, such as low prices, the absence of scarce or toxic elements, the possibility to tune optical properties and long lifetime stability. Therefore, to show the potential of kesterite/silicon tandems, in this work, a 2 terminal (2T) structure using pure germanium kesterite was simulated with combined SCAPS and transfer matrix methods. To explore the impact of individual modifications, a stepwise approach was adopted to improve the kesterite. For the bottom sub cell, a state-of-the-art silicon PERC cell was used with an efficiency of 24%. As a final result, 19.56% efficiency was obtained for the standalone top kesterite solar cell and 28.6% for the tandem device, exceeding standalone silicon efficiency by 4.6% and justifying a new method for improvement. The improvement observed could be attributed primarily to the enhanced effective lifetime, optimized base doping, and mitigated recombination at both the back and top layers of the CZGSSe absorber. Finally, colorimetric analysis showed that color purity for such tandem structure was low, and hues were limited to the predominant colors, which were reddish, yellowish, and purple in an anti-reflective coating (ARC) thickness range of 20–300 nm. The sensitivity of color variation for the whole ARC thickness range to electrical parameters was minimal: efficiency was obtained ranging from 28.05% to 28.63%.

“…Another way is to prepare a special surface optical structure on the surface of the PV cell so that more useful wavelengths of light are refracted into the PV cell and absorbed.

The antireflection coating (ARC) can improve the photoelectric conversion efficiency of photovoltaic (PV) cells. In this paper, the influence of film thickness and refractive index of single-layer and double-layer ARC on solar light absorption under different spectral conditions is simulated by the transfer matrix method. The optimum values of ARC film thickness and refractive index are obtained. To optimize it at AM 0 (air mass 0) solar irradiance, a 66 nm thick SiN x ARC with a refractive index of 2.0 was used. The PV cell’s maximum power density is 89.87. The maximum power density of the PV cell with double-layer SiN x as ARC is 90.94. This work provides a theoretical basis for the application of ARC in ground PV power generation systems and space solar power systems.

“…The industry mainly produces silicon-based solar cells [1]. Although, lots of scientific work has been done to optimize the size [2], surface morphology [3], doping concentration [4] and device structure of silicon-based solar cells, silicon-based solar cells are still considered to have high production cost along with a modest efficiency of 22.8% [5]. In addition, the efficiency of pure silicon-based solar cells cannot exceed the theoretical value of 29% according to the Shockley-Quisser…”

Renewable energy sources like photovoltaics have the potential to mitigate the negative consequences of pollution and global warming. The solar sector has shown exponential growth and is quickly becoming a viable alternative to fossil fuels. Currently, the great majority of solar modules are composed of crystalline silicon. To make photovoltaics more competitive, affordability and efficiency are two of the most important elements. Metal nanoparticles can be introduced or a heterojunction can be made using appropriate materials to increase the absorption coefficient of a silicon-based solar cell, which boost the total efficiency of the solar module. Therefore, in this study, we used Sentaurus TCAD simulation to examine the effects of gold nanoparticles introduced with various sizes and periodicities on the photoelectric characteristics of ZnO/Si and Perovskite/Si solar cells. Accordingly, all of the photoelectric characteristics of the perovskite/Si solar cell have shown a clear sinusoidal connection with the nanoparticle periodicity. When the gold nanoparticle size changed from 6 nm to 9 nm, the period of the sinusoidal function changed to π. The photoelectric parameters of ZnO/Si solar cells changed in a sinusoidal pattern based on the nanoparticle's periodicity, but this was true only when the nanoparticles size was between 9 nm and 21 nm. According to the obtained results, the maximum values of short-circuit current, open circuit voltage and fill factor are 10.47 mA/cm 2 , 0.384 V, 71.06% for perovskite/Si and 10.52 mA/cm 2 , 0.306 V, 71.12% for ZnO/Si. The minimum current density of the perovskite/Si solar cell was identical when compared to the solar cell without nanoparticles. When a gold nanoparticle with a size of 6 nm was introduced into the ZnO/Si solar cell with a periodicity of 120 nm, the short circuit current decreased by a factor of 3.81 compared to the solar cell without the nanoparticle. It has been scientifically proven that Fano interference is responsible for the sinusoidal relationship between the short-circuit current of the solar cells and the periodicity of the nanoparticle.
