Embodiment Construction

[0028] Reference will now be made in detail to specific embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0029] figure 2 It is a schematic top view of a solar cell module 20 according to an embodiment of the present invention. refer to figure 2 , the solar cell module 20 includes a plurality of solar cells 22 - 1 formed on a substrate 21 . In this embodiment, the solar cells 22-1 are electrically connected in series. But in other embodiments, the solar cells 22-1 can be electrically connected in parallel, or a series-parallel combination can be used. The required output voltage and current determine, at least in part, the number of solar cells in the solar cell module and the topology of the solar cell array.

[0030] In an embodiment, the substrate 21 has dimensions of about 52 cm x 11 cm, and each of the ...

Abstract

The invention discloses a device capable of converting solar radiation into electrical energy, which includes a substrate and a plurality of cells formed on the substrate and extending parallel to each other, each of the plurality of cells includes at least one thin film layer and has a size The film thickness distribution depends on the machine capable of forming the at least one film layer.

Description

technical field [0001] The invention relates to a solar cell, more specifically, to a thin-film solar cell module and a manufacturing method thereof. Background technique [0002] Solar energy is one of the most important sources of energy available in recent years. Optoelectronic devices, ie, solar cells, which convert solar radiation into electrical energy according to the photoelectric effect, have attracted great attention. Solar cells, powered by virtually unlimited sunlight without the need to replenish fossil fuels, have been used in satellites, space and mobile communications. In view of the increasing demand for energy saving, efficient use of resources, and prevention of environmental pollution, solar cells have become an attractive energy generation device. [0003] Solar cells can be fabricated on silicon (Si) wafers. However, the cost of generating electricity using wafer-type solar cells is relatively high compared to electricity generation by known methods ...
