Solar cell

The invention provides a solar cell which is provided with a light-transmitting area and comprises a substrate, a photoelectric conversion structure, a metal conductive layer and a shading structure. The photoelectric conversion structure is arranged around the light-transmitting area and comprises a first electrode layer, a photoelectric conversion layer and a second electrode layer which are sequentially arranged on the substrate. The metal conductive layer is arranged around the photoelectric conversion structure. A first gap is arranged between the metal conductive layer and the photoelectric conversion structure. The shading structure completely covers the first gap. The light shielding structure has a first toning layer and a reflective layer stacked on each other. The first toning layer is located between the substrate and the reflective layer. A material of the first toning layer includes one of molybdenum oxide and molybdenum nitride. The reflecting layer is made of molybdenum-tantalum alloy. 本发明提供一种
