Solar cell with improved N-region contact and method of forming the same
Patent
·
OSTI ID:5886376
A method for forming an improved silicon solar cell having a shallow N-type region and a contact characterized by reduced contact resistance is described. The cell is characterized by a silicon semiconductor wafer of P-type material in which a shallow region of N-type material has been diffused. A sintered silver contact formed from silver powder and silver metaphosphate is affixed to the N-type region, establishing a region of increased carrier concentration. Commercial techniques for depositing contacts on the N-type region are briefly reviewed.
