Document Type and Number:
WIPO Patent Application WO/2018/040247
Kind Code:
A1
Abstract:
A solar cell with functional areas prepared by a digital-exponential hybrid doping mode, and a method for preparing the solar cell. Functional areas of a solar cell are prepared by a digital doping and exponential doping cooperated mode. The digital doping and exponential doping cooperated mode refers to: digital doping is carried out sectionally in a doped region, the flow capacity of a dopant is doped into a reaction chamber in a digital transition, and an exponential change occurs between two adjacent doping concentrations. According to the solar cell prepared by a digital-exponential hybrid doping mode, the digital-exponential hybrid doping mode is used in the main functional layers of the solar cell, so that a built-in electric field can be enhanced, and photo-generated carriers can be separated more effectively, and the lifetime of the photo-generated carriers can be prolonged, thereby improving the mobility of the carriers, and increasing an open-circuit voltage of the cell.
