A photovoltaic cell resistant to high temperature and high humidity environment

Abstract

The invention relates to a photovoltaic cell for high temperature high moisture environment resistance, belongs to the solar energy photovoltaic generation production field and solves a problem of photoelectric conversion rate decrease caused by the PID effect because of the high temperature high moisture environment. The photovoltaic cell comprises a crystal silicon substrate, wherein a front side and a back side of the crystal silicon substrate are respectively plated with a layer of an antireflection film. The photovoltatic cell is characterized in that a silicon chip edge of the crystal silicon substrate is plated with an edge protection film, the edge protection film is connected with the antireflection films, and the crystal silicon substrate is completely sealed through the edge protection film and the antireflection films so as to realize complete isolation from the external environment. The photovoltatic cell is advantaged in that properties of reasonable structure design, strong reliability, good economics, light weight and practicality are realized, and the problem of photoelectric conversion rate decrease caused by the PID effect because of the high temperature high moisture environment can be effectively solved.
