“…To address this issue, TFSCs with multiple absorber layers are being explored to increase efficiency and reduce cost [2]. In multiple junction solar cell, the top active layer has usually a wider bandgap and is responsible to capture visible range of the light spectrum, whereas the bottom active layer with low bandgap harnesses the infrared region [1,3,4]. The major problem with the existing tandem TFSCs is poor absorption of incident light due to relatively low absorption coefficient, which essentially reduce the conversion efficiency of the solar cell.…”

Recently, thin-film solar cells have received much attention due to low production cost. However, such cells suffer from low efficiency due to which they cannot be used for practical applications. To cater this problem, we have numerically investigated thin-film tandem solar cells comprising of double active layers made of amorphous silicon (a-Si) and crystalline silicon (c-Si) of different energy bandgaps. The tandem cell is found to absorb large amount of solar photons compared to a single a-Si and c-Si solar cells. To further improve the absorption efficiency, we efficiently utilized the surface plasmon resonance (SPR) effect of plasmonic nanoparticles, which are deposited in the form of a square lattice in the top a-Si active layer. The absorption characteristics of the cell are enhanced and tuned by optimizing the material and size of the nanoparticles. Moreover, periodic disorders are incorporated, which allow mixing of plasmonic modes having different angular momenta, resulting in a super broadband light absorption from 300 to 1100 nm and yielding a short circuit current density of 33.917 mA/cm 2 in the active layers. The proposed plasmonic tandem cell can be advantageous for most of the photovoltaic applications.

“…Each layer with different bandgaps has accountable for converting sunlight into electrical energy beyond Shockley-Queisser Efficiency Limit/SQ Limit. Tandem solar cells are made from organic, inorganic, and hybrid [93]. For example, the combination of the monocrystalline dyesensitized solar cell (DSSC) layer on top of a copper indium gallium selenide (CIGS) thin-film bottom cells.…”

PV solar energy is the upcoming king of the energy source in the world, which is the fastest growing, most available, sustainable, clean, and environmentally friendly renewable energy. The essential characteristic of PV solar energy is generating the maximum power at mid-day. At the same time, the energy demand is high during the daytime. Due to this, PV solar energy replaces the conventional energy demand at peak periods. The sun is the source of PV solar energy, and it changed into electricity directly by using solar cells, which are made from semiconductor materials called silicon. Therefore, PV solar energy plays a crucial role in providing usable energy, and as well as reducing carbon dioxide emissions. However, the solar energy generation systems not achieved the desired efficiency yet, because of many unsolved problems like weather conditions, losses, materials made by and so on. The aims of this paper is to review the current literature on the improvement of the PV solar energy generation system's overall performance. First, to figure out the existing challenges, like environmental factors and natural phenomena that affect the PV solar modules efficiency. Then it presents the techniques that are used to enhance the PV solar modules overall performance. Finally, to propose the best ways and techniques to improve the PV modules efficiency and suggest to further studies.

In this study we present optimized shape, size and material of plasmonic nanoparticles in thin film solar cell. For this purpose, we chose silicon active layer solar cell, on the top of active layer another layer of silicon dioxide was used as antireflection coating. Thickness of ARC layer was kept 71nm. On the top of ARC layer metallic nanoparticles were placed. Parameters of NP’s such as shape, size and material were varied. Respective variations in the absorption of light in the active silicon layer were observed respectively. Absorption patterns were plotted against wavelength range of 400nm to 1400nm of incident light radiation using Finite Element Method (FEM). Results revealed the most optimized size and shape of nanoparticles that can contribute to the absorption of light in the active layer of the solar cell. Results also distinguished the best material for nanoparticle.
