摘要： The present invention relates to methods and apparatuses for providing a buried insulator isolation for solar cell contacts. According to certain aspects, the invention places a buried oxide under the emitter of a polysilicon emitter solar cell. The oxide provides an excellent passivation layer over most of the surface. Holes in the oxide provide contact areas, increasing the current density to enhance efficiency. The oxide isolates the contacts from the substrate, achieving the advantage of a selective emitter structure without requiring deep diffusions. The oxide further enables use of screen printing on advanced shallow emitter cells. Positioning of the grid lines close to the openings also enables use of a very thin emitter to maximize blue response.

摘要： Embodiments of the invention generally contemplate methods for treating a semiconductor solar cell substrate to reduce the number of undesirable material defects or interface state traps on the surface or within the substrate. These defects can adversely affect the efficiency of the solar cell because electron-hole pairs tend to recombine with the defects and are essentially lost without generating any useful electrical current. In one aspect, a method of forming a solar cell on a semiconductor substrate is provided, comprising doping a front surface of the substrate, applying a passivating layer to the front surface and/or a back surface of the substrate, and annealing the substrate to reduce the interface state trap density (Dit).
