Embodiment Construction

[0049] figure 1 is a schematic cross-sectional view of a solar cell module according to an embodiment of the present invention. Please refer to figure 1 , the solar cell module 10 of this embodiment has a light incident surface 10 a and a light reflecting surface 10 b, and the solar cell module 10 includes a substrate 100 , a first solar cell A and a second solar cell B.

[0050] The substrate 100 has a first surface 100a and a second surface 100b. The substrate 100 can be a rigid substrate (such as a glass substrate, a silicon substrate) or a flexible substrate (such as an organic polymer substrate), preferably a flexible substrate. If the substrate 100 is a flexible substrate, the solar cell module 10 of this embodiment can be manufactured by a continuous roll to roll manufacturing process.

[0051] The first solar cell A includes a first electrode layer 110 , a first active layer 112 and a second electrode layer 114 .

[0052] The first electrode layer 110 is located on...

Abstract

The invention discloses a solar cell module, comprising a light incident face and a light reflecting surface. The solar cell module comprises a substrate, a first solar cell and a second solar cell. The substrate comprises a first surface and a second surface. The first solar cell comprises a first electrode layer disposed on the first surface of the substrate, a first active covering the first electrode layer, a second electrode layer covering the first active layer which absorbs the light within a first wavelength range. The first solar cell comprises a first electrode layer disposed on the first surface of the substrate, a first active covering the first electrode layer, a second electrode layer covering the first active layer which absorbs the light within a first wavelength range which absorbs the light within a second wavelength range. The surface of the second electrode layer of the first solar cell is used as the light incident face, and the surface of the fourth electrode layer of the second solar cell is used as the light reflecting surface.

Description

technical field [0001] The present invention relates to a solar cell module, and in particular to an organic solar cell (organic photovoltaic cell, OPV) module. Background technique [0002] In recent years, the awareness of environmental protection has been on the rise. In order to cope with the shortage of petrochemical energy and reduce the impact of using petrochemical energy on the environment, the research and development of alternative energy and renewable energy has become a hot topic, among which solar cells (photovoltaic cells) have attracted the most attention. Solar cells can directly convert solar energy into electrical energy, and no harmful substances such as carbon dioxide or nitride will be produced during the power generation process, and will not pollute the environment. [0003] Generally speaking, in a conventional solar cell, a first electrode layer, an active layer and a second electrode layer are formed on a substrate. When the light beam irradiates ...
