SUBSTRATE OF PHOTOVOLTAIC CELL AND PHOTOVOLTAIC CELL CONTAINING THE SAME

摘要

PURPOSE: A solar cell board and a solar cell including the same are provided to obtain a light transmission rate over 80% in a wavelength range between 900 and 1100 nm by reducing a resonant phenomenon among dopant, zinc elements, and oxygen elements. CONSTITUTION: A ZnO thin film layer(512) doped with dopant is formed on a transparent substrate(511). The ZnO thin film layer has a (1011) of 3% or more in comparison with a (0002) crystal surface based on an X ray diffraction pattern(XRD). A foreign material elution preventing layer(513) is formed between the ZnO thin film layers and prevent foreign materials from being eluted from the inside of a transparent substrate.
