Investigating the electron tunneling effect on photovoltaic performance of almond (Prunus dulcis) dye-sensitized solar cell

A block solver of variable step variable order (BSVSVO) is suggested for stiff ordinary differential equations (ODEs). The block solver is employed to enhance the performance for stiff ODEs via variable step variable order to achieve faster convergence with better accuracy and lesser maximum error. Block solver is formulated via interpolation and collocation together with power series as the basis function approximation. The principal local truncation error (PLTE) of the block solver is utilized to generate the convergence criteria. Some investigation of the theoretical properties will be mentioned and analyzed. The block solver will be implemented using some selected test problems and compared with existing methods to showcase the convergence, high efficiency and accuracy thereby ensuring a better maximum error of the suggested method.

A Block Solver of Variable Step Variable Order for Stiff ODEs

Influence of n-Mosfet transistor on dye-sensitized solar cell efficiency.

We investigate the influences of photoanode on light scattering and absorption in a
dye-sensitized solar cell (DSSC). N719 dye on a monolayer anode of TiO2 film
and ZnO film, are compared in terms of their photovoltaic conversion efficiency.
Doctor blade application and high temperature sintering of photoanode assemblage
on indium doped tin oxide glass was adopted for preparation of the two
photoanodes. The optical density of the interfacial layer relative to the
photogenerated carriers is determined by absorption of ionic electrolytes. The
outcome obtained with different photosensitizing effect of organic
T.danielliimolecules on DSSCs showed a wide disparity, the highest Voc was
recorded with Br- with 500 mV and 79 mV respectively for TiO2 and ZnO
photoanode respectively. Three important morphological characterization
techniques were used, scanning electron microscopy (SEM) with energy dispersive
spectrum (EDS), Electron shell occupancy and Entropy were discussed in detail
with respect to their photoelectric performance, the best Iscwas 0.035 mA with Br-
on TiO2 attributable to a large optical density, achieved from ratio of area of
molecular coverage of nanoparticle film. Scanning electron microscopy (SEM)
revealed a structure consisting of direct and ordered paths for photogenerated
carriers to the collecting electrodes, the Pmaxresult reported was 36.54 mW with Br-
from TiO2.
