Description
Technical Field
The utility model belongs to the technical field of photovoltaic cell equipment, and particularly relates to a feeding component of a light injection furnace for photovoltaic cells.
Background
In recent years, photovoltaic development is rapid, and a battery piece is an important component in photovoltaic power generation, and the quality of the battery piece directly influences the power generation efficiency. Photo-injection refers to injecting photo-energy into a semiconductor material to cause it to excite electrons to transition from the valence band to the conduction band, thereby forming electron-hole pairs. This process requires that the photon energy be greater than the bandgap energy of the semiconductor material to be able to excite the electron transition. The principle of light injection is based on the photoelectric effect of a semiconductor material, i.e. after photon energy is absorbed, electrons are excited to transition from the valence band to the conduction band, thereby forming electron-hole pairs.
In the field of solar cells, light injection is also an important element in the fabrication of the cells. The photo-induced degradation is a phenomenon of power degradation caused by solar cells and components during the process of illumination, and it is believed that the main reason for photo-induced degradation of P-type (boron doped) solar cells is that in the case where boron and oxygen must exist in a silicon material at the same time, illumination or current injection causes boron and oxygen to form a boron-oxygen (B-O) complex, which is a metastable defect, forming a recombination center and thus reducing minority carrier lifetime.
In the prior art, aiming at the cause of photoinduced attenuation, a series of solutions are developed in the industry, such as reducing the oxygen content in a silicon wafer, using gallium element to replace part of boron element, reducing the boron content and the like to reduce the photoinduced attenuation, but the methods have high cost or high technical difficulty and cannot realize mass production, wherein the method that hydrogen atoms introduced by preparing a medium passivation film through light injection or electric injection can promote the failure of a B-O complex is a better method;
therefore, a light injection device with large light intensity and controllable temperature, which can pre-attenuate the illumination of the battery piece and has obvious light attenuation resistance, is developed. The utility model mainly provides feeding assembly equipment of a light injection furnace.
