example 1

[0194] by and reference Figures 6 to 10 The same method as described is used to fabricate organic thin film solar cell modules in which solar cell devices are formed into multi-slope structures.

[0195] More specifically, a 150 nm thick ITO layer was first deposited on a 150 μm thick PEN substrate by sputtering. The substrate has a width of 28 mm and a length of 420 mm. Then, by using DL 1000 manufactured by TORAY, a polyimide film having a width of 6 mm was formed as the insulating layer 14 on the ITO layer by photolithography.

[0196] Subsequently, while the strip-shaped substrates are continuously supplied to the coating unit, a hole transport / injection layer, an active layer, and an electron transport / injection layer are sequentially deposited, and a cathode is deposited by vaporization. Immediately before depositing the hole transport / injection layer by coating, the surface is UV cleaned by using a UV cleaner, thereby removing foreign substances from the surface and ...

Abstract

A solar cell module according to an embodiment includes a solar cell device (1) and a support structure (21a, 21b) supporting the solar cell device (1). The solar cell device (1) is a belt-like solar cell device including first portions (1a) arranged in one direction (X1) such that major surfaces thereof face each other, and a second portion (1b) interposed between the first portions (1a). The edges of the first portions (1a) that correspond to a pair of long sides of the solar cell device (1) are parallel to each other. Two adjacent first portions (1a) incline forwardly and backwardly with respect to the one direction (X1). The second portion (1b) includes one or more planar or curved surfaces to connect the two adjacent first portions (1a) to each other.

Description

[0001] Cross References to Related Applications [0002] This application is based upon and claims the benefit of priority from prior Japanese Patent Application No. 2011-059905 filed on March 17, 2011, the entire contents of which are incorporated herein by reference. technical field [0003] Embodiments described herein relate generally to solar cell assemblies. Background technique [0004] An organic thin film solar cell is a solar cell using an organic thin film semiconductor such as a mixture of a conductive polymer and fullerene. Compared with solar cells using inorganic materials such as silicon, copper indium gallium selenide (CIGS), and CdTe, organic thin film solar cells have an advantage that they can be produced at low cost by a simple method. On the other hand, organic thin film solar cells have a problem of being inferior to conventional inorganic solar cells in power conversion efficiency and lifetime. This is because factors that are difficult to control, ...
