Abstract
A solar cell has a photoelectric conversion semiconductor layer and an electrode made of a material containing a conductive base material and a resin binder electrically connected to the photoelectric conversion semiconductor layer, wherein the volume of voids in the electrode having a diameter of 0.1 .mu.m or greater is 0.04 ml/g or less.
Claims5
A method of fabricating a solar cell comprising a photoelectric conversion semiconductor and an electrode comprising a conductive base substance and a resin binder, said electrode electrically connected to said photoelectric conversion semiconductor, said method comprising the steps of:
- forming a conductive paste comprising said conductive base substance and said resin binder in which the amount of solvent contained therein is adjusted so as to be not more than 18 wt % based on the weight of the conductive paste, whereby the volume of voids in said electrode having a diameter of 0.1 .mu.m or greater is 0.04 cc/g or less;
- applying said conductive paste to a surface of said photoelectric conversion semiconductor;
- and
- forming said electrode by curing said conductive paste.
