The aim of this work is to investigate the effect of anti-reflection coating to improve the performance of silicon solar cell. The reflectance for different anti-reflection coating materials (SLARC and DLARC) were calculated numerically as well as on online source of PV Education. The parameters of such materials are used in PC1D simulator to study the performance of solar cells. It was found that DLARC has considerable effect on the performance of solar cell as compare to SLARC. Further, it was observed that the photovoltaic efficiency and short circuit current is significantly high for SiO2/TiO2 DLARC.

Abstract:A systematic quantum mechanical study of the possible conformations, their relative stabilities, vibrational and electronic spectra and thermodynamic parameters of methyl-3-methoxy-2-propenoate has been reported for the electronic ground (S 0 ) and first excited (S 1 ) states using time-dependent and time-independent Density Functional Theory (DFT) and RHF methods in extended basis sets. Detailed studies have been restricted to the E-isomer, which is found to be substantially more stable than the Z-isomer. Four possible conformers c Cc, c Tc, t Cc, t Tc, of which the first two are most stable, have been identified in the S 0 and S 1 states. Electronic excitation to S 1 state is accompanied with a reversal in the relative stability of the c Cc and c Tc conformers and a substantial reduction in the rotational barrier between them, as compared with the S 0 state. Optimized geometries of these conformers in the S 0 and S 1 states are being reported. Based on suitably scaled RHF/6-31G** and DFT/6-311G** calculations, assignments have been provided to the fundamental vibrational bands of both these conformers in terms of frequency, form and intensity of vibrations and potential energy distribution across the symmetry coordinates in the S 0 state. A complete interpretation of the electronic spectra of the conformers has been provided.
