Embodiment Construction

[0031] The following disclosure provides many different embodiments, or examples, for implementing different features of the inventive subject matter. Specific examples of components and arrangements are described below to simplify the present disclosure. Of course, this is just an example, but not intended to limit the present invention. For example, in the following description, the formation of the first component over or on the second component may include an embodiment in which the first component and the second component are formed in direct contact, and may also include an embodiment in which the first component and the second component are formed between the first component and the second component. Embodiments in which additional parts are formed such that the first part and the second part are not in direct contact. In addition, the present invention may repeat reference numerals and / or letters in each example. This repetition is for brevity and clarity, but does n...

Abstract

A tandem solar module includes first and second thin film solar cell circuits and a transparent coupling layer disposed between the first and second thin film circuits for securing the first and second thin film circuits together in a stack. Each solar cell circuit includes a multi-layer structure, the multi-layer structure including a substrate, a first conductive layer formed over the substrate, a buffer layer, an absorber layer formed between the first conductive layer and the buffer layer, and a second conductive layer formed over the buffer layer. The first thin film solar cell circuit and second thin film solar cell circuit are oriented with respect to one another such that the absorber layers are disposed between the substrates of the circuits. The first and second solar cell circuits have different bandgap profiles.

Description

technical field [0001] The present invention relates to solar cell modules, and more particularly, to thin film solar cell modules. Background technique [0002] Conventional thin-film solar cell modules such as CIS-based solar cell modules (e.g., CuInGa(di)Se or CuInGa(di)Se) have only a single junction, and their conversion efficiency is limited due to large thermalization losses. limit. Contents of the invention [0003] In order to solve the defects existing in the prior art, according to one aspect of the present invention, a series solar cell module is provided, comprising: a first thin film solar cell circuit including one or more thin film solar cells; a second thin film solar cell a circuit disposed under the first thin film solar cell circuit and including one or more thin film solar cells; and a transparent connection layer disposed between the first thin film solar cell circuit and the second thin film solar cell circuit space, and the first thin film solar c...
