Cu2Zn1−yFeySnS4-based solar cells with different mole fractions of iron have been analyzed using numerical simulations in this study. The analysis deals with the effect of the iron content on the overall electrical performance of solar cells. Results revealed that the Voc is affected by the increase of the iron content even if it improves the other parameters. We found that the CZFTS solar cell with a mole fraction of iron equal to 1 (CFTS) showed the best results in terms of power conversion efficiency (PCE). Moreover, variations of several structural and physical parameters of the buffer CdS and the best absorber CFTS on the overall electrical characteristics of the cell were investigated. Simulations showed promising results with PCE of 20.35%, Jsc of 26.09 mA/cm2, Voc of 0.93 V, and FF of 83.93%. The results obtained can serve as a basis for the design and manufacture of high-efficiency CZFTS solar cells.

The measurements of solar radiation for Biratnagar (BRT), Kathmandu (KTM), Pokhara (PKR) and Jumla (JML) have been undertaken using CMP 6 pyranometers from SAHR/IOE/TU, Nepal. Solar radiation and the other meteorological data have been collected from the archives of Department of Hydrology and Meteorology, Government of Nepal (DHM/GoN) to analyze the daily Global Solar Radiation (GSR). In this study, perovskite-based solar cells with the configuration Au/SpiroOMETAD/MAPbI3/TiO2/FTO have been simulated using Solar Cell Capacitance Simulator (SCAPS). The power conversion efficiency (PCE) of the cell is found to be 22.67, 22.69, 22.77 and 22.80% in BRT, KTM, PKR and JML respectively, almost similar and better performance, whereas the solar cell performs better in JML due to the high solar irradiance.

AbstractOver the last decade, nanotechnology and nanomaterials have attracted enormous interest due to the rising number of their applications in solar cells. A fascinating strategy to increase the efficiency of organic solar cells is the use of tailor-designed buffer layers to improve the charge transport process. High-efficiency bulk heterojunction (BHJ) solar cells have been obtained by introducing hollow core polyaniline (PANI) nanofibers as a buffer layer. An improved power conversion efficiency in polymer solar cells (PSCs) was demonstrated through the incorporation of electrospun hollow core PANI nanofibers positioned between the active layer and the electrode. PANI hollow nanofibers improved buffer layer structural properties, enhanced optical absorption, and induced a more balanced charge transfer process. Solar cell photovoltaic parameters also showed higher open-circuit voltage (+ 40.3%) and higher power conversion efficiency (+ 48.5%) than conventional architecture BHJ solar cells. Furthermore, the photovoltaic cell developed achieved the highest reported efficiency value ever reached for an electrospun fiber-based solar cell (PCE = 6.85%). Our results indicated that PANI hollow core nanostructures may be considered an effective material for high-performance PSCs and potentially applicable to other fields, such as fuel cells and sensors.

Current Research Interest

Considering the current research interest in Organic / Inorganic (ZnO) hybrid solar cells structures in developing advanced photovoltaic devices, three different types of solar cell structures are proposed. In the proposed structures, hybrid solar cell composed of ZnO nanoparticles are used as an electron-acceptor material and PEDOT:PSS is intruded in between the nanoparticles, which reported to possesses power-conversion efficiency in excess of 8%. The use of p-ZnO layer results to improve the device performance on the rigid substrate. The power-conversion efficiency of the developed solar cell was found to be as high as 10% when measured under AM 1.5G illumination. Further, simulations have been carried out whose results are in line with experimental results.

In today's era, a lot of interest is gained by solar cell formed by combination of organic and inorganic nano-particle semiconductors mainly because of its major features such as scalable solar power conversion and cost effectiveness, which makes the cell a desirable photovoltaic device. This piece of work is an attempt to make a solar cells by the combination of zinc oxide (ZnO) and graphite. ZnO is a good n-type material for the application in photovoltaic (PV) devices due to its better optical, electrical, structural, and environmentally friendly properties, and on the other hand, graphite, an organic semiconductor, enhances the rate of charge transfer in the device. These materials are so designed to help bring in more understanding in a wider range of the solar spectrum. This work focuses on developing solid-state polymer and hybrid solar cells.

Thin-film solar cells are currently an important research subject. In this study, a lattice-matched GaNAsP/Si tandem cell was designed. We adopted the drift-diffusion model to analyze the power conversion efficiency (PCE) of the solar cell. To find the maximum solar cell PCE, the recombination terms and the interlayer between subcells was omitted. For an optimal tandem cell PCE, this study analyzed the mole fraction combinations of GaNAsP and the thickness combinations between the GaNAsP and the Si subcells of the tandem cell. Our results showed the superiority of the tandem cell over the Si cell. The 4.5 μm tandem cell had a 12.7% PCE, the same as that of the 10.7 μm Si cell. The 11.5 μm tandem cell had 20.2% PCE, while the 11.5 μm Si cell processed 12.7% PCE. We also analyzed the Si subcell thickness ratio of sub-12 μm tandem cells for maximum PCE. The tandem cell with a thickness between 40% to 70% of a Si cell would have a max PCE. The ratio depended on the tandem cell thickness. We conclude that the lattice-matched GaNAsP/Si tandem cell has potential for ultrathin thin Si-based solar cell applications.

The power conversion efficiency (PCE) of an Ag/spiro-OMeTAD/CH3NH3PbI3 (MAPbI3)/PCBM/mesoporous TiO2/compact TiO2/FTO planar solar cell with different annealing temperatures of PbI2 and MAPbI3 films was investigated in this study. The morphology control of a MAPbI3 thin film plays key roles in high-efficiency perovskite solar cells. The PbI2 films were prepared by using thermal vacuum evaporation technology, and the MAPbI3 perovskite films were synthesized with two-step synthesis. The X-ray spectra and surface morphologies of the PbI2 and MAPbI3 films were examined at annealing temperatures of 80, 100, 120, and 140 °C for 10 min. The performance of the perovskite planar solar cell at an annealing temperature of 100 °C for 10 min was demonstrated. The power conversion efficiency (PCE) was about 8.66%, the open-circuit voltage (Voc) was 0.965 V, the short-circuit current (Jsc) was 13.6 mA/cm2, and the fill factor (FF) was 0.66 by scanning the density–voltage (J–V) curve.
