Problems solved by technology
[0003] In the prior art, when perovskite solar cell components are cut and scribed multiple times to form sub-cells, a large dead zone will be formed. Since photoelectric conversion cannot be generated in the dead zone, the power of perovskite solar cell components will be affected. Boost does not contribute

Embodiments of the present application provide a thin-film solar cell assembly, a manufacturing method thereof, and an electrical device, which belong to the technical field of solar cells. The thin film solar cell assembly is provided with a plurality of first notches, a plurality of second notches and a plurality of third notches along the first direction. The second groove includes a plurality of sub-grooves spaced along the second direction, the third groove includes a plurality of semi-closed areas and connecting portions spaced along the second direction, each semi-closed area on both sides along the second direction Each is connected with a connecting portion, each semi-closed area at least partially surrounds a sub-cut groove, and the first cut groove is disposed toward the opening of the semi-closed area. The present application can reduce the distance between the first notch and the third notch, effectively reduce the dead zone area between the first notch and the third notch, thereby increasing the effective power generation area and reducing the dead zone area caused by The resulting current loss of the thin-film solar cell module improves the output efficiency of the entire thin-film solar cell module.
Description
technical field [0001] The embodiments of the present application relate to the technical field of solar cells, and in particular, to a thin-film solar cell assembly, a method for manufacturing the same, and an electrical device. Background technique [0002] Thin-film solar cells are optoelectronic devices that directly generate electricity from sunlight, and have the advantages of small mass, thin thickness, flexibility, and low raw material cost. In recent years, solar thin-film cells have developed rapidly, accounting for an increasing proportion of photovoltaic power generation. At present, the industrially prepared solar thin film battery materials mainly include cadmium telluride, copper indium gallium selenide, amorphous silicon, gallium arsenide, perovskite and other thin film batteries. In the field of photovoltaics in recent years, perovskite thin-film solar cells are a new type of cell with great potential to replace the dominance of silicon-based solar cells. ...
