The present disclosure relates to the technical field of solar cells. Disclosed are a solar cell, a preparation method therefor and a use thereof. A P-type doped region and an N-type doped region are alternately arranged on the back surface of a crystalline silicon substrate; a boron diffusion doped layer, a first passivation layer and a first anti-reflection layer are sequentially formed in the P-type doped region; and a phosphorus-doped silicon oxide layer, a phosphorus-doped polycrystalline silicon layer, a second passivation layer and a second anti-reflection layer are sequentially formed on the surface of the crystalline silicon substrate in the N-type doped region. The P regions of traditional TBC cells mostly adopt a two-step process of depositing intrinsic amorphous silicon and performing boron diffusion to form a polycrystalline silicon layer. However, the P region of the present disclosure does not contain a polycrystalline silicon layer, and can be prepared by a one-step boron diffusion process, which can reduce the process steps and shorten the process time. The interaction between laser and the polycrystalline silicon in the P region is also avoided, the difficulty of cell patterning is reduced, and the production yield of cells can be greatly improved.

0001 The invention relates to the development of an enhanced luminescent solar concentrator panel employing a unique method for capturing and concentrating the maximum amount of solar energy in a specific area using an "inverse" focusing effect. The solution involves a luminescent solar panel that absorbs all incident energy without dispersion in the opposite wall (no semitransparency). 0002 This type of enhanced luminescent solar concentrator operates with sunlight and consists of a transparent material, an intermediate zone made up of a diffusive layer and multiple internally reflecting and focusing cones, a horizontal discontinuous reflective layer beneath the cones, a second reflective layer at the panel's base, and photovoltaic strips positioned along the lateral edges of the transparent portion. 0003 Sunlight striking the panel is diffused by the pigment and trapped underneath through a funnel-shaped zone directed by an inverse optical lens. Thanks to reflection between the intermediate layer and the lower reflective base of the panel, the trapped light remains concentrated and is transferred by reflection to the photovoltaic elements. 0004 This invention is innovative because it enables the creation of an enhanced luminescent solar concentrator (LSC) panel that absorbs the majority of incident energy while reducing losses. This application is highly effective as it can be used as a cladding for opaque surfaces (non-glazed) for green energy generation, and i
