A conductive paste composition, including aluminum powder; an organic carrier including an organic solvent and resin or cellulose; and phenoxy alkyl alcohol accounting for 2˜10% of weight of the conductive paste composition. The conductive paste composition includes the phenoxy alkyl alcohol, and thus resultant conductive paste not only has enhanced surface tension, but also has an increased difference in surface tension between the resultant conductive paste and a cell to therefore alter wetting behavior between the paste and a silicon wafer, to reduce the broadening behavior of the wiring lines printed, increase the aspect ratio of printing wiring, increase the light-receiving area of the solar cells, and enhance the photovoltaic conversion efficiency of the solar cells (especially local back surface field solar cells and PERC bifacial cells).
