    Abstract: Dye sensitized solar cells (DSSC) are used for photovoltaic applications. The paper presents a methodology for optical and electrical modeling of dye-sensitized solar cells (DSSCs). In order to take into account the influence of the overlap distance between two TiO2 particles on the cell an optoelectronic model for DSSC is presented in this paper. ... Show More

    Abstract: Acceleration Doppler Effect is introduced to explain the Redshift phenomenon in Inertia Transformation process. Hubble’s Law and Cosmological Redshift are interpreted by Wu’s Spacetime Accelerating Shrinkage Theory. In addition, Wu’s Laws of Spacetime of Wu’s Pair and Photon with respect to the age of universe and the gravitational field are derive... Show More

    Abstract: Exact solution for spherically symmetric isotropic charged fluid sphere are investigated relativistic model of an electrically charged compact star, and energy density associated with the electric fluids is on the same order of magnitude as the energy density of fluid matter itself. The analytic solution depicts a unique static charged configuratio... Show More
