Solar cell module

Abstract

he invention provides a solar cell module. The solar cell module comprises a backboard layer (10), a first packaging material layer (20), a cell sheet layer (30), a second packaging material layer (40) and a glass layer (50) which are successively superposed. The solar cell module also comprises a barrier layer (60) used for preventing metal cations of the glass layer (50) from entering into the cell sheet layer (30). The barrier layer (60) is arranged between the glass layer (50) and a second packaging material layer (40). By using the solar cell module of the invention, a problem of a PID phenomenon existing in the solar cell module in the prior art is effectively solved.

Description

technical field [0001] The present invention relates to the technical field of solar cells, in particular to a solar cell component. Background technique [0002] Solar energy, as an emerging green renewable energy, has the characteristics of zero carbon dioxide emissions and inexhaustible energy sources. Solar cell module power generation can effectively reduce carbon dioxide emissions, and its position in the global energy strategy is becoming more and more important. With the continuous increase in the scale of photovoltaic power plants, the differences and uncertainties in the installation and use environments have led to a series of problems such as the reduction of power generation of power plants and the decline in the power of solar cell modules. As one of the causes of power degradation of solar cell modules, the phenomenon of potential induced degradation (PID) has attracted widespread attention. In 2005, Sunpower, a famous American photovoltaic manufacturer, fou...
