Solar battery with power grid conversion layer and manufacturing method

Abstract

The invention discloses a solar battery with a power grid conversion layer and a manufacturing method. The solar battery comprises an upper silicon plate and a lower silicon plate; upper silicon plateconductive strips are distributed and embedded in the upper surface of the upper silicon plate; a tempered glass layer is glued on the upper surface of the upper silicon plate; a lens layer is gluedon the upper surface of the tempered glass layer; a phosphorus-doped layer is integrally formed on the lower surface of the upper silicon plate; lower silicon plate conductive strips are distributed and embedded in the lower surface of the lower silicon plate; a reflective layer is glued on the lower surface of the lower silicon plate; a bearing layer is glued on the lower surface of the reflective layer; a boron-doped layer is integrally formed on the upper surface of the lower silicon plate; the boron-doped layer is tightly fitted with the phosphorus-doped layer; a power grid conversion layer is sandwiched between the boron-doped layer and the phosphorus-doped layer; through the lens layer, light ray polymerization is performed, so that the amount of light rays guided to the solar battery is increased, and absorption amount is further increased; and then by enabling the power grid conversion layer to be sandwiched in the PN junction, electron flowing speed in the PN junction is improved, the original conductive efficiency is improved, and the conversion efficiency of the solar battery is improved.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a solar cell with a power grid replacement and a manufacturing method. Background technique [0002] Solar energy has become an emerging new energy source, and the common solar cell mainly forms a PN junction by phosphating and boronizing the silicon plate, and then realizes the unidirectional flow of current through the PN junction, and then realizes that the solar cell converts solar energy into a single However, generally speaking, the flow rate of electrons in the PN junction determines the efficiency of the solar cell in converting solar energy into electrical energy. Generally, the flow rate of electrons in the PN junction is relatively slow, and the conversion efficiency is low, so it needs A large-area battery panel is needed when a large amount of power is supplied, so we propose a solar battery and a manufacturing method.
