Embodiment approach

[0059] For the basis Figure 9 to Figure 1 One embodiment of the invention of 5 considers two unit solar cell modules.

[0060] Each unit solar cell module is composed of a plurality of unit solar cells arranged in a row.

[0061] Figure 13 A patterning process of the photoelectric conversion layer 303 is shown. First, patterning for separating the photoelectric conversion layer 303 into two unit solar cell modules is performed.

[0062] In other words, the patterning 303c of separating the photoelectric conversion layer into the upper unit solar cell module 303b and the lower unit solar cell module 303a is performed. Patterning may be performed in left and right directions to separate the photoelectric conversion layer into an upper unit solar cell module and a lower unit solar cell module.

[0063] In order to form unit solar cells in the unit solar cell modules separated up and down, each photoelectric conversion layer corresponding to the upper unit solar cell module ...

Abstract

The present invention relates to a photovoltaic conversion apparatus including a by-pass diode and a manufacturing method thereof. The photovoltaic conversion apparatus of the present invention comprises at least one unit solar cell module configured of at least one unit solar cell; and a by-pass solar cell module including at least one solar cell electrically connected to the unit solar cell to by-pass current. According to the present invention, a photovoltaic conversion apparatus having high photoelectric conversion efficiency can be manufactured. Also, the photovoltaic conversion apparatus will contribute to earths environmental conservation as the next clean energy source and can be directly applied to private facilities, public facilities, military facilities, etc., to create enormous economic value.

Description

technical field [0001] The present invention relates to a photoelectric conversion device with a bypass diode and a method of manufacturing the same. [0002] More specifically, the present invention relates to a solar cell module structure including a solar cell having a bypass diode, and to a method of manufacturing the solar cell module structure to overcome the Problems with current limiting and hot spot generation. Background technique [0003] The outlook for the fossil fuels we've been using so far is grim. In 2003, according to the prediction of British Petroleum (BP: British Petroleum), an oil refining company from the United Kingdom, considering the mineable fossil fuel reserves, crude oil can be used for about 40 years, natural gas can be used for about 62 years and coal can be used for about 216 years . However, due to the emergence of large energy consuming countries such as China and India, it is estimated that it will be shorter than the forecast period. F...
