Abstract
A positive conductive transparent conductive oxide and a solar cell having the positive transparent conductive oxide are disclosed. The positive transparent conductive oxide comprises a Molybdenum trioxide doped with an element carrying less than six valence electrons. The element carrying less than six valence electrons is selected among the group of Alkali group, Alkaline earth group, third group element, fourth group element, fifth group element, transition element carrying less than six valence electrons, and the combination thereof. Through the number of holes increased by the dopant of the element carrying less than six valence electrons, the hole mobility is increased and the Fermi level is closer to the range of positive materials, so that said oxide becomes a positive transparent conductive material. The positive transparent conductive oxide not only has high hole mobility and low resistance, but also has the transparency rate within the range of visible wavelength as high as 88%, and thereby is quite adequate for the positive conductive layer of a solar cell.
