Solar cell and method of manufacturing the same

A solar cell comprising:

• a substrate containing impurities of a first conductive type, the substrate having a textured surface including a plurality of jagged portions;
• an emitter layer covering the textured surface, the emitter layer containing impurities of a second conductive type, wherein the conductivity of the second type is opposite the conductivity of the first conductive type, and wherein the emitter layer has a textured surface, over the textured surface of the substrate, including a plurality of jagged portions that generally align with the plurality of jagged portions of the substrate;
• a first electrode electrically connected to the emitter layer;
• a second electrode electrically connected to the substrate, wherein a concentration of the impurities of the second conductive type within the emitter layer is greatest in a proximity to a peak of each jagged portion, such that a sheet resistance near the peak of each jagged portion is less than that of a remaining portion of each jagged portion,
• wherein the first electrode comprises a plurality of first metal particles and a plurality of second metal particles, and each of the plurality of first metal particles is a recrystallized particle of second metal particles,
• wherein a diameter of all the plurality of first metal particles is greater than a peak-to-peak distance between adjacent jagged portions of the emitter layer,
• wherein a diameter of all the plurality of second metal particles is greater than the diameter of each of the plurality of first metal particles,
• wherein first metal particles, and not second metal particles, are in contact with the plurality of jagged portions of the emitter layer,
• wherein the diameter of each of the plurality of second metal particles is about 2 μm to about 5 μm.
