摘要： Processes for making light to current converter devices are provided. The processes can be used to make light to current converter devices having P-N junctions located on only the top surface of the cell, located on the top surface and symmetrically or asymmetrically along a portion of the inner surface of the via holes, located on the top surface and full inner surface of the via holes, or located on the top surface, full inner surface of the via holes, and a portion of the bottom surface of the cell. The processes may isolate the desired P-N junction by etching the emitter, forming a via hole after forming the emitter, using a barrier layer to protect portions of the emitter from etching, or using a barrier layer to prevent the emitter from being formed on portions of the substrate.

摘要： This invention discloses a process of phosphorus diffusion for manufacturing solar cell, comprising annealing a mono-crystalline silicon wafer in a nitrogen atmosphere at 900-950° C. for twenty to thirty minutes, carrying oxidation treatment in a hydrogen chloride atmosphere at 850-1050° C. to form a 10 to 30 nm thick oxide layer on the surface of said silicon wafer, diffusing from a phosphorus source at 850-900° C., until a block resistance of a material surface is controlled at 40 to 50 ohms, and the junction depth is at 0.2 to 1.0 microns, and annealing in a nitrogen atmosphere at 700-750° C. for thirty to sixty minutes to complete the phosphorus diffusion of said mono-crystalline silicon wafer. This invention allows the use of 4 N˜5 N mono-crystalline silicon as the material for manufacturing solar cells, so, the low purity material such as metallurgical silicon can be used, which greatly reduces the cost of materials.
