Problems solved by technology

However, when some solar cells in the crystalline silicon solar cell photovoltaic module in the prior art are shaded, the power loss of the local solar cells of the photovoltaic module will be too high, resulting in a significant rise in local temperature, resulting in a hot spot effect. Affect the power output and reliability of photovoltaic modules, causing unnecessary losses

Abstract

An embodiment of the invention discloses a solar cell photovoltaic module which comprises multiple cell strings in mutually parallel connection. Two ends of each cell string are connected with an anode and a cathode of the solar cell photovoltaic module respectively, and each cell string comprises multiple cell pieces in mutually parallel connection, so that when the solar cell photovoltaic module works, part of the cell pieces are shielded, normal working of other cell pieces cannot be influenced, hot spot effect is solved fundamentally, performance and reliability of the solar cell photovoltaic module are improved, and unnecessary loss is lowered.

Description

technical field [0001] The invention relates to the technical field of solar cell manufacturing, in particular to a solar cell photovoltaic module. Background technique [0002] With the increasing tension of fossil fuels, solar energy, as a clean, pollution-free and inexhaustible new energy source, has become the energy guarantee for the future development of mankind. Today's global photovoltaic market is dominated by crystalline silicon solar cell photovoltaic modules, which have the advantages of abundant raw materials, high conversion efficiency, high reliability, simple structure and long life. [0003] Crystalline silicon solar cell photovoltaic modules are devices that convert light energy into electrical energy by using the photovoltaic effect of the P-N junction of silicon materials. However, when some solar cells in the crystalline silicon solar cell photovoltaic module in the prior art are shaded, the power loss of the local solar cells of the photovoltaic module...
