AbstractThe invention relates to a method for manufacturing photoelectric cell that can convert light energy to electric energy. N++P-N-, intermixing structure of N++P+N- and P+N-, P++N+P-, and intermixing structure of P++N+P- and N+P- are adopted as photoelectric cell in the invention. External electrical source is used as energy pump and the cell almost does not consume energy. Silicon thermal photoelectric cell absorbing infrared ray is made by method of high doping. Photocurrent of the invented photoelectric cell is 4.2 times as high as the photocurrent of international highest level 0.92 A/W. With 1.5 volt bias voltage being applied, the cell gives 415 times as high as said level.
