Problems solved by technology

Solar cells are mainly based on semiconductor materials. Its working principle is to use photoelectric materials to absorb light energy and then undergo photoelectric conversion reactions. The power generation of solar cells is related to the illuminated area. The larger the illuminated area, the more power generated. Typical photovoltaic materials It only reacts to light of a specific frequency and color, especially for infrared rays. Most solar cells do not absorb infrared rays and cannot use their energy effectively, so the utilization efficiency of solar energy is low

Abstract

The invention discloses a graphene solar cell which comprises a shell and a supporting plate arranged above the shell. The shell and the supporting plate form a sealed cavity. Graphene power generation material is arranged above the supporting plate. A junction box is arranged in the sealed cavity. The graphene power generation material is provided with two electrodes which pass through the supporting plate to be connected with the junction box. The bottom of the junction box is provided with two leads which are both threaded out of the shell. The graphene solar cell adopts the graphene power generation material which can absorb infrared rays in sunlight and be used as energy source of power generation. The utilization rate of solar energy is effectively improved. Moreover, the graphene power generation material is low in cost, and has higher power generation capacity than a traditional silicon solar cell under the condition of same area.
