The utility model discloses a quartz furnace tube is used in solar cell diffusion, including the quartzy mouth of pipe, the outer cross -section of the quartzy mouth of pipe is circular, the interiorcross -section of the quartzy mouth of pipe is with the silicon chip and bears the weight of the quartz boat matched with shape of silicon chip. The utility model discloses a when quartz furnace tubeis used in solar cell diffusion can guarantee that the furnace gate of the quartzy mouth of pipe is in the open mode, the cold air and the impurity that get into the boiler tube reduced relatively, can reduce the time of rising again, improve the diffusion productivity, can avoid the pollution of external impurity again to improve the cleanliness factor of diffusion and improve solar cell's conversion efficiency. 本实用新型公开了种太阳能电池扩散用石英炉管，包括石英管口，所述石英管口的外截面为圆形，所述石英管口的内截面为与硅片以及承载所述硅片的石英舟相配合的形状。本实用新型的种太阳能电池扩散用石英炉管能够保证石英管口的炉门处于打开状态时，进入炉管的冷空气和杂质相对减少，既能减少回温时间、提高扩散产能，又能避免外界杂质的污染，从而提高扩散的洁净度而提高太阳能电池的转换效率。
