Solar power generation is a technically viable method, although the main drawback is the cost. Traditional silicon-based single-crystal photovoltaics are too expensive to compete with non-renewable energy, while alternative materials such as cadmium telluride and copper-indium-gallium-selenide contain expensive and unstable elements, while cadmium is a carcinogen. Za is known. Copper-zinc-tin sulfide (CZTS) is another alternative, although the technology is not yet advanced enough to enter the market. The present work is a study on the synthesis of CZTS nanostructures using aerosol spray pyrolysis based on CZTS nanostructures for photovoltaic applications in an inexpensive, environmentally friendly and industrially extensible manner. We dissolve a precursor solution with air-soluble copper, zinc, and tin compounds and pass the droplets through the furnace, where the precursors dissolve to form CZTS structures thermally. Using this method, we can produce thin films - by placing a substrate inside the furnace - and nanoparticles. Manuscript profile -

To overcome these problems, Solar cells is important as an energy source and free from contamination. Due to the increasing use of renewables, the use of solar cells for obtaining energy is growing. The cells convert directly sunlight into electricity by the photovoltaic. Photovoltaic energy research and development is generally done in two areas: cost reduction and increasing efficiency. The efficiency of thin film solar cells canbe increased considerably by coupling the solarcells with plasmonic nanoparticles (NPs). this study investigates, through meticuloussimulations, the effects of plasmonic nanoparticle shapes and size on theimprovement of the energy conversion efficiency of CIGS solar cells. Two different shapes including spheres and cylinders were analyzed in this study.It was revealed that the cylindrical Agnanoparticles, of diameter 50 nm, height 125 nm place on an array with period 215 nm exhibited the most substantialenhancement in the optical absorption and electrical currentgeneration.

However, CZTS devices show poor efficiency and identifying deficiencies and making improvements is necessary. In the present study, various anti-reflection coatings at the top surface of the solar cell were proposed. Minimization of the reflectance is carried out to optimize the thickness of ARC layers using Lumerical software. The density of the short-circuit photocurrent increases from 18.4 mA.cm−2 for solar cells without an antireflection coating to 36 mA.cm−2 for those with MgF2 layer coating. Manuscript profile -

In this paper, simulation of CdTe based solar cell (ZnO/ZnCdS/CdTe/NiO/Al) has been presented. ZnCdS, NiO and ZnO layers have been used as electron/hole transport layer (ETL/HTL) and transparent conductive oxide (TCO) layer, respectively. SCAPS-1D simulation software was used to evaluate the performance of the modelled multijunction CdTe solar cell. This software is capable of analyzing the efficiency with different parameters of cadmium telluride solar cell. The impact of thickness, carrier concentration, defect density of the CdTe, and ZnCdS/ CdTe interface defect density on the solar cell performance was also investigated. The optimized solar cell demonstrated a maximum power conversion efficiency (PCE) of 26.3 % with open circuit voltage (VOC) of 1.095 V, short circuit current density (JSC) of 27.22 mA/cm2 and FF of 88.14 % that shows huge promise in low-cost solar energy harvesting.

The solar cells with polymeric counter electrode were fabricated, in variable thicknesses by two spin coating and drop coating methods, and evaluated. In addition, the effect of nanowires and titanium dioxide nanoparticles concentration, present in photo-anode, was investigated on the performance of solar cell. The absorption amount of N719 dye was studied by spectrophotometer, and the maximum absorption was obtained at the wavelengths of 380 and 530 nm. The structural investigation of photo-anode and counter electrode by scanning electron microscope showed that the combination of nanoparticles and titanium dioxide nanowires with 1:9 ratio leads to a porous structure with a high surface-to-volume ratio that has a significant effect on the absorption of the dye and solar cell efficiency. The prepared solar cell by the drop coating method did not have appropriate performance. So, the focus of the research was directed towards the sample prepared by spin coating method. The solar cell sample with the counter electrode, containing polypyrrole/polyaniline, fabricated by spin coating method offers the open circuit voltage of 0.71 V, short circuit current of 2.58 mA, fill factor of 57.38, and efficiency of 1.05, which open circuit voltage and fill factor have been improved by 7.6 and 35 times compared to similar samples, respectively.

However, perovskites are sensitive to parameters such as humidity, oxygen, temperature, and electrical bias. Changes in the composition and structure of materials from the precursor to the resulting perovskite lead to various defects. During long-term operation, these defects often act as the initiation of degradation to deteriorate PSC performance. A series of methods have been developed to prevent contact between the corrosive environment and perovskite. For this purpose, various techniques have been designed to control these parameters, which include removing corrosion sites during construction, eliminating corrosion sites during machine operation, and preventing contact between the corrosive environment and perovskite. In this review, the lifetime of PSC is discussed from the point of view of corrosion science. Finally, the use of a series of anti-corrosion strategies (passivation, surface coating, machining) in corrosion science significantly increases the stability of perovskite cells.

According to the photo absorption spectrum obtained within UV-Vis and NIR regions, the ternary cells based on OA and MA4PbI6 capped PbS exhibit enhanced photon harvesting efficiency compared with their binary counterpart cell. The steady state photoluminescence results reveal efficient electron transfer from photoexcited P3HT to QDs and hole transfer from photoexcited QDs to P3HT, leading to the improved power conversion efficiency (PCE) of the ternary cells. However, compared with OA, the semiconducting perovskite )MA4PbI6) ligand shows to be much more effective in increasing power conversion efficiency, so that 6% improvement in PCE is seen by the introduction of 6% PbS QD capped with perovskite ligand unlike PbS QD with OA ligand which had adverse effect on the photovoltaic properties of p 3HT: PC61BM solar cell. This is explained to be due to the insulating characteristic of long chain OA as well as improved charge carrier transport in the case of PbS capped perovskite based ternary solar cells.

Due to their better cost-effectiveness, they can replace silicon-based solar cells in the market if their efficiency and stability increase. The design and development of DSSCs have involved not only experimental and laboratory work but also numerical modeling. The aim of this work is to design and numerically model dye-sensitized solar cells based on a nanostructured semiconductor layer with a wide bandgap (titanium dioxide) and zinc oxide as the electron transporter, N719 dye as the absorber layer, and PEDOT:PSS and P3HT as hole transport materials. In this research, the advanced software CAMSOL with extensive capabilities is used for the design of dye-sensitized solar cells, and the current-voltage characteristics and optical absorption of the cell are calculated, which are in agreement with experimental data.
