Problems solved by technology

In this method, since the disc-shaped semiconductor single crystal wafer is cut and formed into a quadrangular shape, there is a problem that crystal loss in an arcuate shape occurs.
Even if it is set in small blocks, if the total 12m 2 If the solar power generation system of the unit is set on the roof, there will often be a dead zone where modules cannot be configured (non-configurable parts)
Furthermore, one module weighs 15kg, making it difficult to install on the roof

Abstract

The object of the present invention is to provide a photovoltaic power generation module and a photovoltaic power generation system using the bow-shaped battery that has no loss of a disk-shaped single crystal wafer, and provide an operating voltage per unit area. (also referred to as "area voltage") high photovoltaic power generation modules and photovoltaic power generation systems using the same, and providing photovoltaic power generation modules and photovoltaic power generation systems that can increase the effective installation area ratio of modules relative to residential roofs Solar power generation system. The module for photovoltaic power generation is composed of arcuate cells divided from disc-shaped single-crystal silicon photovoltaic cells for photovoltaic power generation. more than one bus bar, and the arcuate cells are arranged in a grid shape, and the solar power generation module is characterized in that 14 to 42 arcuate cells with an area of ​​28 to 65 cm2 are arranged.

Description

technical field [0001] The invention relates to a solar power generation module and a solar power generation system formed by arranging a plurality of monocrystalline silicon solar power generation cells. Background technique [0002] Until now, cells for photovoltaic power generation (also called "solar cells" or "batteries") have been manufactured from rectangular polycrystalline silicon wafers obtained by slicing rectangular parallelepiped polycrystalline silicon ingots. Solar cells using semiconductor single crystal silicon wafers have higher energy conversion efficiency than solar cells using polycrystalline silicon or amorphous silicon. In addition, single crystal silicon wafers are also relatively cheap, so they will become the main force of popular solar cells in the future. At this time, a solar cell is manufactured using a disk-shaped wafer obtained by slicing a cylindrical ingot. [0003] For example, a semiconductor single crystal obtained by Czochralski single ...
