Abstract

The invention discloses a method for converting solar energy into electric energy through electromagnetic induction. The method is characterized by comprising the following steps: polishing and cleaning a polymer membrane to prepare a polymer basal membrane whose surface is provided with a groove; coating a layer of optical active polymers on the surface of the polymer basal membrane to prepare a double-layer composite membrane with an optical active polymer membrane formed on the surface of the polymer basal membrane; fixing a permanent magnet on a three-dimensional mobile platform A to form a fixed set, forming a cantilever beam at the near end, where the double-layer composite membrane is fixed, of a three-dimensional mobile platform B, and adhering an induction coil at the far end of the cantilever beam to form a moving set; and enabling a beam of sunshine, after being converged via a convex lens, to be irradiated at the near end of the cantilever beam, the optical active polymer membrane being contracted and deformed, the polymer basal membrane being not contracted, and enabling the double-layer composite membrane to be bent towards an illumination direction to drive the far-end moving set to move to generate the electromagnetic induction with the fixed set so as to obtain voltage and current and convert the solar energy into the electric energy. According to the invention, a new purpose is opened up for the optical active polymers, and the method can be applied to the field of photoelectric conversion of the solar energy.
