<p>The present invention discloses a solar cell photovoltaic panel and a light gathering power device having the solar cell photovoltaic panel. The technical problem to be resolved is to improve the efficiency of the solar cell. The photovoltaic panel, two surfaces of the silicon chip are manufactured by semiconductor technology separately, and the two surfaces of the silicon chip form two PN junctions with photoelectric effect, there are electrode wirings set on the surfaces of two junctions. A light gathering power device having photovoltaic panel, there is a reflector sheet below the surface of the silicon sheet, the reflector sheet is set on the reflector control device. Compared with the existing technology, the two surfaces of the silicon chip of the invention are manufactured by semiconductor technology separately, and the two surfaces of the silicon chip form two PN junctions with photoelectric effect. The invention forms two solar cells on the positive and negative surfaces respectively, and the photovoltaic current is the sum of positive and negative surfaces. This can take full advantage of sunlight, make photovoltaic current increase significantly and improve the efficiency of the photoelectric.</p> |
