Solar energy cell

The invention discloses a solar energy cell which comprises a light converging assembly, a light spot conversion assembly and a photoelectric conversion chip, wherein the light converging assembly is used for collecting sunlight and converging the collected sunlight to form convergent light; the light spot conversion assembly comprises a top surface, a bottom surface and a peripheral surface, the top surface is made of a transparent material to form a light entrance, the bottom surface is made of the transparent material to form a light exit, the peripheral surface is made of a nontransparent material, a reflecting layer is coated on an inner wall of the peripheral surface, the light entrance is connected with the light converging assembly, so that the convergent light enters a light spot converter through the light entrance, and the convergent light formed by the light converging assembly is homogenized and reshaped through reflection in the light spot conversion assembly, so that processed light beams are uniformly transmitted according to the shape of the light exit; the photoelectric conversion chip is located below the light exit of the light spot conversion assembly, and the shape and size of the photoelectric conversion chip are matched with that of the light exit. The solar energy cell can be used for obviously improving the distribution of light radiation on the photoelectric conversion chip and increasing the utilization rate and reliability of the photoelectric conversion chip.
