Solar cell with enhanced anti-reflection effect

The utility model discloses a solar cell with enhanced anti-reflection effect, which comprises a silicon wafer substrate, and at least two layers of anti-reflection films with the same or different film thicknesses are deposited on one side or two sides of the silicon wafer substrate. According to the utility model, a plurality of layers of antireflection films with different thicknesses are deposited on the surface of the solar cell, the antireflection performance of the antireflection films is improved through multiple reflection and refraction, and the antireflection performance of the solar cell in the whole absorbed spectral region is also improved. And meanwhile, the antireflection property of the MgF2 film is applied, so that the solar cell obtains a better antireflection effect, and the photoelectric conversion efficiency of the solar cell is improved. 本实用新型公开了一种具有增强减反效果的太阳能电池，包括硅片基底，在硅片基底的单面或者双面沉积至少两层具有相同或不同膜厚的减反射膜。本实用新型通过在太阳能电池的表面沉积了多层具有不同厚度的减反射膜，通过多次反射和折射不仅增加了减反射膜的增透性，而且提高了太阳能电池在所吸收的整个光谱区的增透性。同时运用了
