Couple models are a standout amongst the most encouraging ideas towards prevalent power transformation efficiencies of natural sun based cells. An exact assurance of the power transformation productivity requires rectification of the otherworldly confuse and in this manner depends on precise outer quantum effectiveness (EQE) spectra. Because of the arrangement association of 2 sub cells in the pair design, the EQE of the couple sun powered cell repeats the EQE of one sub cell if a fitting inclination light is picked to specifically enlighten and henceforth forward predisposition the other sub cell. The subsequent inner voltage drop is then repaid by applying an outside voltage to the pair sunlight based cell. In this work, we use impedance spectroscopy to precisely foresee the base predisposition light force and the outer voltage to empower exact EQE estimations on both sub cells. We embody this method on natural couple sun oriented cells involving frightfully integral safeguards and recommend an all-inclusive convention for future estimations of the EQE

AbstractThis article aims to study MoSe2/CIGS tandem solar cells employing SCAPS-1D computational package based on ant colony algorithm. The simulation of Monolithic MoSe2/CIGS tandem solar cells has been implemented successfully by employing the Matlab/Simulink. The power output of the Monolithic MoSe2/CIGS tandem modules increases by the solar irradiations during the first few days of operation. The J–V characteristic and average daily energy production throughout the year has been calculated. The results show 80.71% FF and 19.29% efficiency of the solar cell. The other parameter for the MoSe2/CIGS tandem solar cell are Voc = 0.62 V; Jsc = 38.69 mA/cm2.

This work is a pioneer attempt to fabricate quasi-solid dye-sensitized solar cell (QSDDSC) based on organosoluble starch derivative. Rheological characterizations of the PhSt-HEC blend based gels exhibited viscoelastic properties favorable for electrolyte fabrication. From amplitude sweep and tack test analyses, it was evident that the inclusion of LiI improved the rigidity and tack property of the gels. On the other hand, the opposite was true for TPAI based gels, which resulted in less rigid and tacky electrolytes. The crystallinity of the gels was found to decline with increasing amount of salt in both systems. The highest photoconversion efficiency of 3.94% was recorded upon addition of 12.5 wt % TPAI and this value is one of the highest DSSC performance recorded for starch based electrolytes. From electrochemical impedance spectroscopy (EIS), it is deduced that the steric hindrance imposed by bulky cations aids in hindering recombination between photoanode and electrolyte.

Organic solar cells have potential as an alternative to conventional inorganic solar cell due to low processing cost, flexibility and easy fabrication technique. The goal of this paper is to study the characteristics of the CuPc and PCBM based organic solar cell by introducing a thin layer of Ag at the interface of donor (CuPc) and Acceptor (PCBM), their photovoltaic and optical properties were investigated. The heterojunction solar cells with and without silver inter layer were fabricated through thermal deposition in HR vacuum. The OPV solar cells were characterized using current-voltage graphs, absorbance spectrum and Impedance spectroscopy. Impedance spectroscopy was taken to identify the traps using series resistance, parallel resistance, and Impedance spectrums under different frequencies. Optical behaviors of these devices have been investigated with absorbance spectrum. Introducing Ag to interfacing point produced traps and these traps causes to decreased Voc, Isc, FF, and efficiency. The effect of silver layer at donor acceptor interface was studied.
