Abstract:
The invention relates to a horizontal electrode structure solar cell and manufacturing method thereof which produces the most optimized horizontal electrode structured solar cell, avoid the influence by structural deformity where the lattice misfits the dislocation of the growth regulator, and substrate is generated. The horizontal electrode structure solar cell of the present invention has an effect to increase the efficiency because the reduction does not occur since the carrier is not transmitted in the misfit dislocation layer, and the efficiency is improved by the influence of the deformity of the solar cell of which a thin film is included. The invention also comprises a wide band gap layer formed on the upper part of the thin film and the ohmic layer, the first electrode formed at the upper part of the wide band gap layer into a predetermined thickness and the device layer, and the second electrode formed in the upper part of the device of the ohmic layer. At the same time, the lattice mismatch substrate including the substrate formed on the substrate, and the lattice of the misfit dislocation of the lattice constants are included in the present invention.
