摘要： A solar cell having an improved structure of rear surface includes a p-type doped region, a dense metal layer, a loose metal layer, at least one bus bar opening, and solderable material on or within the bus bar opening. The solderable material contacts with the dense aluminum layer. The improved structure in rear surface increases the light converting efficiency, and provides a good adhesion between copper ribbon and solar cell layer thereby providing cost advantages and reducing the complexity in manufacturing. A solar module and solar system composed of such solar cell are also disclosed.

摘要： This invention discloses a novel method for fabricating solar cells. Using the existing screen-printing, masking or photolithography techniques, a P-type or N-type diffusion source is coated on the sites of an N-type or P-type silicon wafer desired for forming electrodes. Then, a low dose P-type or N-type diffusion source is in situ diffused into the N-type or P-type silicon wafer together with the P-type or N-type diffusion source coated on the N-type or P-type silicon wafer in the furnace. Thereafter, a P−/P+ or N−/N+ diffusion region is formed within the N-type or P-type silicon wafer. Finally, electrodes aligned to the P+ or N+ diffusion region are formed by means of screen-printing. Then, a solar cell with high photocurrent and low series resistance can be obtained.
