摘要

PROBLEM TO BE SOLVED: To provide a conductive oxide fine particle dispersion liquid for forming a transparent conductive film for a super straight type solar cell and the transparent conductive film formed using the dispersion liquid, which greatly reduce contact resistance in a longitudinal direction with respect to the film and, as a result, when constituting a solar cell, increase a fill factor which is one of the factors that determine conversion efficiency, as well as a composite film and a method of manufacturing them.;SOLUTION: The conductive oxide fine particle dispersion liquid used to manufacture a transparent conductive film formed on a photoelectric conversion layer of the super straight type solar cell and constituted by a first layer containing a binder component and a second layer formed on the first layer and containing a less binder component compared with the first layer is prepared by dispersing the conductive oxide fine particles in a dispersion medium, and it is adjusted so that, assuming that a frequency of all particles of the conductive oxide fine particles in a number-based particle size distribution is 100%, the frequency of particles whose diameters are 50 nm or more is 70-100% and also the frequency of particles whose diameters are 200 nm or more is 10% or less.;COPYRIGHT: (C)2011,JPO&INPIT
