Summary: | The utility model discloses a quartz furnace tube for preparing a solar battery; a sealing quartz furnace tube which is generally used is changed into the quartz furnace tube with two opening at two ends, two small lathy quartz air tubes are fixed on the inner wall of the furnace tube by the openings, the atmosphere in the furnace tube is ensured to be uniform by air holes which are uniformly distributed on the small quartz air tubes, thereby solving the problem that square resistance is uneven caused by uneven air current among batches in the diffusion process for preparing the solar battery, reducing gas consumption, improving the stability of conversion efficiency of batteries, greatly reducing the manufacturing cost and improving the service life of the products. |
