| titleOfInvention | A kind of PERC solar-energy photo-voltaic cells for improving photoelectric transformation efficiency |
| abstract | The invention discloses a kind of PERC solar-energy photo-voltaic cells for improving photoelectric transformation efficiency, including silicon substrate film and respectively direct sintering silicon substrate film side to light and the back side positive electrode and back electrode, silicon dioxide layer, the first passivation layer, antireflection layer, conductive film and clear glass are disposed with the side to light of silicon substrate film, the back side of silicon substrate film is disposed with the second passivation layer and aluminium back surface field, and metal nano-particle layer is additionally provided between conductive film and clear glass；Solar-energy photo-voltaic cell simple structure of the invention, on the one hand the absorption of light is improved, using Surface Texture and the coated with antireflection layer of sunken light, on the other hand the recombination rate of battery surface is reduced, it is passivated using passivation layer, backside passivation layer preferably reduces the back surface recombination rate of silicon chip so that the minority carrier life time of silicon chip reaches maximization, optimize the opening ratios of backside passivation layer simultaneously, so as to greatly improve solar cell photoelectric conversion efficiency. |
