Abstract

A solar battery assembly and preparation method thereof. The solar battery assembly comprises: multiple solar battery groups interconnected by means of connection strips. Each solar battery group comprises an N-type solar battery plate (1) and a P-type solar battery plate (2). The illuminated sides of the N-type solar battery plate (1) and of the P-type solar battery plate (2) are connected by multiple, thin first connection strips (302). Adjacent solar battery groups are arranged such that an N-type solar battery plate (1) is next to a P-type solar battery plate (2), and multiple second connection strips (304) connect the non-illuminated sides of the N-type solar battery plate (1) and of the P-type solar battery plate (2) of the two adjacent battery groups. The second connection strips have a larger total cross-sectional area in the direction of electrical currents. The reduction of the light-blocking area of the first connection strips (302) enables more sunlight to enter the battery for photoelectric conversion. The increase of the cross-section area of the second connection strips (304) on the non-illuminated sides raises the density of current collected, thereby further enhancing the photoelectric conversion rate.

Abstract

Disclosed is a heat field structure of single crystal furnace for removing the deposition of volatile components on the exterior of the heat shield. The heat field structure comprises a furnace chamber (1), in which a heat insulating cylinder (2), a heat shield assembly and a crucible (3) are arranged. The heat insulating cylinder (2) surrounds the exterior of crucible (3), and the heat shield assembly is covered over the heat insulating cylinder (2) to form a closed heat field. A protective gas, fed into the upper part of furnace chamber, flows downwards through the heat shield assembly into the crucible (3), and then flows upwards through the gap between the heat shield assembly and the crucible (3) into a heat insulating chamber formed by the heat shield assembly and the heat insulating cylinder (2). Gas-guide holes (4) are opened on the heat shield assembly, through which the protective gas directly comes into the upper part of furnace chamber. Both end openings of the gas-guide holes are higher than the upper edge of the crucible (3). The gas flow structure inside the gap between the heat shield assembly and the heat insulating cylinder (2) is improved by the gas-guide holes (4) which are opened on the heat shield assembly to guide a minority of protective gas to the top space between the assembly and the cylinder (2), therefore avoiding the retention and deposition of gas rich in volatile components thereon.

Abstract

The present invention relates to the technical field of the production of solar cells, especially to an impurity gettering process for polysilicon. The silicon wafers firstly undergo a high temperature phosphorus diffusion gettering treatment to dissolve impurities of the metal precipitates and of the metallic composite in silicon. Subsequently the wafers undergo a low temperature phosphorus diffusion gettering treatment, through the differences of the impurity segregation coefficients in different regions, to effectively diffuse the impurity atoms into the phosphorus diffusion region and to get a uniform diffusion region. Through the impurity gettering process, the silicon wafers are more purified, which provides a better basis for the following fabrication of the solar cells and may greatly improve the transform efficiency of the final solar cells.
