Disclosed are a solar cell and a solar cell module comprising same, the solar cell comprising: a solar cell structure having one or more hollows passing therethrough in the height direction, and a plurality of light-concentrating parts disposed in each of the one or more hollows.

A solar-powered generator captures solar energy and generates steam with the energy. The generator includes a container formed with an inner spherical wall defining an inner chamber and having an inner reflective surface containing photovoltaic cells and an outer spherical wall defining an outer chamber located between the inner and outer spherical walls. The container is formed to allow for sunlight to enter the inner chamber. An inlet port is configured to allow water to enter the outer chamber and an outlet port is configured to allow steam to exit the outer chamber, whereby sunlight entering the inner chamber through the passage bounces off of the inner reflective surface allowing thermal energy to heat the water in the outer chamber to create steam to generate electricity through an external steam turbine. While simultaneously using radiant energy to be absorbed by photovoltaic cells to generate additional electricity.

A solar panel manufacturing apparatus includes a stage on which a substrate is placed, a pressing plate to press an adhesive applied on the substrate and thereby spread the adhesive via a solar cell arranged at a predetermined position on the adhesive, and to retain the position of the solar cell relative to the substrate, and a curing unit to cure only a part of the adhesive spread between the substrate and the solar cell, while the pressing plate is pressing the adhesive and retaining the position of the solar cell relative to the substrate.

The technology of this application relates to a cell assembly and a method for preparing a cell assembly. The cell assembly includes a first subcell, a second subcell adjacent to the first subcell, and a bottom electrode. Both the first subcell and the second subcell include a P-type layer and an N-type layer, and a light-harvesting layer located between the P-type layer and the N-type layer. The P-type layer of the first subcell is connected to the N-type layer of the second subcell by using the bottom electrode. A connection manner between subcells is provided. Compared with a current manner in which P1, P2, and P3 gaps are formed between subcells through cutting to implement interconnection, geometrical optical loss brought by interconnection between the subcells can be reduced.
