Abstract
The present invention discloses photovoltaic glass and a photovoltaic module. The photovoltaic glass comprises a glass plate, a groove is formed in one surface of the glass plate, and a first bus barand an insulating bar are arranged in the groove; the photovoltaic module comprises the photovoltaic glass, the photovoltaic glass is a front glass plate, and the front glass plate comprises a first surface with an AR antireflection film and a second surface with a suede; the arrangement structure of the battery pieces of the photovoltaic module is as follows: for L battery string groups, each battery string group comprises M columns of battery strings, each column of battery strings comprises N multi-piece pieces, each battery string group is provided with a second bus bar connected to the first bus bar in parallel and a third bus bar led out of the photovoltaic module and connected with the junction box, the third bus bar comprises a positive wiring end and a negative wiring end, and thefirst bus bar is arranged between the two columns of battery strings or on the outer sides of the battery strings. Compared with the prior art, the cost is saved, the production efficiency is improved, and the power generation efficiency of the photovoltaic module is also improved.
Description
technical field [0001] The invention relates to the technical field of solar power generation equipment, in particular to a photovoltaic glass and a photovoltaic module. Background technique [0002] Photovoltaic power generation is a power generation technology that directly converts solar energy into electrical energy by using the photovoltaic effect at the semiconductor interface. At present, photovoltaic power generation has been widely concerned by countries all over the world, and has developed into a new industry. Photovoltaic modules are formed by connecting several single solar cells in series and in parallel, and hermetically sealed. String welding, connecting the front electrode of the previous battery with the back electrode of the next battery, heating and welding together, and so on, connecting the battery pieces in series to form a battery string, and then typesetting the welded battery string and connecting it with the second battery string. A bus bar is we...
