Crystalline silicon solar cell, crystalline silicon-perovskite laminated cell, corresponding preparation method and photovoltaic module

Abstract

The embodiment of the invention provides a crystalline silicon solar cell, a crystalline silicon-perovskite laminated cell, a corresponding preparation method and a photovoltaic module. The crystalline silicon solar cell comprises a first transparent conductive layer, a back surface field structure, a silicon substrate, a passivation contact structure and a second transparent conductive layer which are stacked in sequence, and the back surface field structure is a laminated structure for forming a back surface field on the back surface of the silicon substrate. According to the crystalline silicon solar cell, the passivation contact structure is formed on the front surface of the silicon substrate, the back surface field is formed on the back surface of the silicon substrate, the transparent conductive layers are stacked on the front surface and the back surface of the crystalline silicon solar cell, and the second transparent conductive layer can passivate hydrogenation bonds on the surface of a silicon wafer and has conductivity; therefore, the front and back electrodes of the crystalline silicon solar cell can be prepared by adopting low-temperature slurry, and the crystalline silicon solar cell is prevented from being damaged by high temperature.
