Abstract

The invention relates to a series type integrated photovoltaic module including the components as following: a first cell and a second cell formed by in-sequence laminated a lower electrode, a photoelectric conversion layer including a plurality of unit cell layers and an upper electrode. The lower electrode of the first cell is isolated from the lower electrode of the second cell by a lower electrode isolating chanel, and a plurality through holes are formed on the photoelectric conversion layer of the second cell by isolation for connecting the upper electrode of the first cell to the lower electrode of the second cell.

Description

technical field [0001] The invention relates to a serial integrated photoelectric module and a manufacturing method thereof. Background technique [0002] At present, with the prediction that existing energy sources such as oil and coal will be exhausted, people are paying more and more attention to alternative energy sources to replace these existing energy sources. Among them, solar energy has attracted special attention because of its abundant resources and non-polluting environment. [0003] Like diodes, photovoltaic modules that convert solar energy into electricity have a junction structure of p-type semiconductors and n-type semiconductors. When light hits the photoelectric module, there is an interaction between the light and the material that constitutes the semiconductor in the photoelectric module, generating electrons with (-) charges and holes with (+) charges, and the flow of charges generates current. [0004] Photoelectric modules are classified into bulk t...
