  • Patent number: 11990550
    Abstract: A semiconductor structure and a method for forming the same are provided. The semiconductor structure includes a gate structure formed over a fin structure, and a source/drain (S/D) epitaxial layer formed in the fin structure and adjacent to the gate structure. The semiconductor structure also includes a S/D silicide layer formed on the S/D epitaxial layer, and the S/D silicide layer has a first width, the S/D epitaxial layer has a second width, and the first width is smaller than the second width. The semiconductor structure includes a dielectric spacer between the gate structure and the S/D silicide layer, and a top surface of the dielectric spacer is lower than a top surface of the gate structure.

  • Patent number: 10883002
    Abstract: 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).

  • Publication number: 20200295206
    Abstract: A conductive paste composed of an aluminum powder, an organic carrier consisting of an organic solvent and resin or cellulose, a glass powder, and a lead oxide. A total content of the glass powder and the lead oxide is from about 1.0 to 6.0 wt % of the conductive paste; and a content of the lead oxide is from about 0.5 to 3.0 wt % of the conductive paste. The conductive paste contains specific percentages of glass powder and lead oxide and can be used in manufacturing solar cells, and the solar cells so manufactured can have increased photovoltaic conversion efficiency without the need of using any expensive laser drilling apparatus, large plant space and any precision-alignment printing machine. With these advantages, the conductive paste is able to promote photovoltaic industry upgrading.

  • Patent number: 10608128
    Abstract: An aluminum paste used for local back surface field solar cells is introduced. The aluminum paste which has large-sized aluminum powder; an organic vehicle including a solvent and a resin or cellulose; wherein a ratio of a median particle size (?m) to an oxygen content (%) (median particle size (?m)/oxygen content (%)) of the large-sized aluminum powder ranges from 10 to 15. The aluminum paste used for local back surface field solar cell and the local back surface field solar cell using the aluminum paste eliminate the powder extraction of aluminum powder, the aluminum beads, the adhesion of the aluminum layer to the SiNx capping layer, and the void issue occurred at the LBSF positions, which further improves the photoelectric conversion efficiency of the local back surface field solar cell.

  • Publication number: 20160272820
    Abstract: A conductive aluminum paste for a local back surface field solar cell includes an aluminum powder; an organic carrier including a resin and a solvent; and a vanadium oxide. A solar cell which includes the conductive aluminum paste is further provided. Both the conductive aluminum paste and the solar cell enhance the photoelectric conversion efficiency of the local back surface field solar cell and the pulling strength even though its lead content is reduced or it is lead-free.

  • Publication number: 20160208112
    Abstract: A conductive aluminum paste for a high-efficiency solar cell includes an aluminum powder, an organic carrier, and at least a rare earth element oxide. The rare earth element oxide accounts for a maximum 5% of the total weight of the conductive aluminum paste. A solar cell including the conductive aluminum paste is further provided. The conductive aluminum paste and the solar cell are effective in enhancing solar photovoltaic conversion efficiency and eliminating warpage without increasing the content of the fine aluminum powder.

  • Publication number: 20160208113
    Abstract: A conductive aluminum paste which has a low printed weight and is suitable for use with a solar cell includes an aluminum powder, an organic carrier, and at least one of a vanadium source, a phosphorus source, and a molybdenum source. The vanadium source, phosphorus source, or molybdenum source accounts for a maximum 0.5% of the total weight of the conductive aluminum paste. A solar cell including the conductive aluminum paste is further provided. Due to its low printed weight, the conductive aluminum paste, coupled with the solar cell, maintains satisfactory electrical properties and pull, incurs low manufacturing cost, enhances water tolerance, and reduces warpage.
