| Zusammenfassung: | The invention relates to a solar cell which comprises a substrate, a light-condensing solar cell element and a film solar cell element, wherein the substrate is provided with a first surface and a second surface which are relatively arranged, the light-condensing solar cell element is arranged on the first surface, and the film solar cell element is arranged on the second surface, therefore, on aclear day, most of lights are in parallel light incidence, and the light-condensing solar cell element has high photoelectric conversion efficiency; in poor weather, most of lights are scattered light and can be absorbed by the film solar cell element, thereby promoting the photoelectric conversion efficiency. |
