Abstract

The invention discloses a novel dual-glass photovoltaic module. The novel dual-glass photovoltaic module comprises front glass, a front EVA adhesive film, solar cell pieces, a rear EVA adhesive film and rear glass, wherein a plurality of grooves are formed in a front surface of the rear glass, a bypass diode is arranged in each groove, the bypass diode is arranged on a non-solar cell piece region, a cable and a connector are arranged on a back surface of the rear glass, the solar cell pieces are connected in series to form a plurality of solar cell strings by using soldering strips, a plurality of convergence belts are arranged at an upper part and a lower part of the module and are used for connecting the solar cell strings, each bypass diode is connected in series and in parallel with a corresponding solar cell, and a positive electrode and a negative electrode of the bypass diode are respectively connected with a negative electrode and a positive electrode of the corresponding solar cell string. By forming the grooves in the rear glass, many bypass diodes are arranged in the module, optimal protection function is provided for the module, and maximum output power of the module is ensured; moreover, a junction box is omitted, and the module cost is reduced; and meanwhile, the reliability of the module can also be improved.

Description

technical field [0001] The invention relates to the technical field of solar energy, in particular to a novel double-glass photovoltaic module. Background technique [0002] As a clean, pollution-free renewable energy source, solar energy has received more and more attention in recent years, and the application range of photovoltaic modules has become more and more extensive. At present, the mainstream application in the market is crystalline silicon photovoltaic modules. According to their different structures, they can be divided into single-glass photovoltaic modules and double-glass photovoltaic modules. Single-glass photovoltaic modules occupy a large market share. [0003] Double-glass photovoltaic module refers to a composite layer composed of two pieces of glass and solar cells, and the photovoltaic cell module is formed by connecting wires in series and parallel to the lead terminals between the cells. Due to the use of standard photovoltaic glass on the front and ...
