Abstract

The invention discloses a photovoltaic power generation device, and relates to the technical field of solar cells. The photovoltaic power generation device comprises a first photovoltaic assembly anda second photovoltaic assembly, wherein the first photovoltaic assembly and the second photovoltaic assembly respectively comprise an odd number of solar cell string groups which are connected in series, a first connector and a second connector, the first photovoltaic module further comprises a first bypass diode, the first end of the solar cell string group at the edge of one side of the first photovoltaic module is connected with the first connector through the first bypass diode, the second end of the solar cell string group is connected with the second connector, the first end of the solarcell string group at the edge of one side in the second photovoltaic module is connected with the second connector, the second end is connected with the first connector, and the first photovoltaic assembly and the second photovoltaic assembly are connected through the first connector and the second connector at the edge of one side. According to the embodiment, the number of bypass diodes used inthe photovoltaic module comprising an odd number of solar cell string groups is reduced, and the power generation efficiency of the photovoltaic module is improved.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a photovoltaic power generation device. Background technique [0002] In order to meet the safety of the internal circuit of the photovoltaic module, the solar cell strings in the photovoltaic module are generally connected in parallel with bypass diodes to prevent the cells in the solar cell string from being burned due to the hot spot effect. [0003] At present, in a photovoltaic module including an odd number of solar cell strings, each pair of solar cell strings is connected in parallel with a bypass diode, and the remaining 1 solar cell string needs to be connected to a bypass diode in the form of a flying lead using an independent bus bar. road diode. That is to say, in a photovoltaic module with an odd number of solar cell strings, one solar cell string inevitably needs to be connected in parallel with a bypass diode, which causes waste of materials to a certain exte...
