The utility model relates to a quartz boat for diffusion of crystalline silicon solar cells tubular, including a plurality of connecting rods and a plurality of carrier bar, wherein the quantity morethan or equal to no. 3 of carrier bar, in crystalline silicon solar cells inserts the recess of at least three carrier bar, and the position of recess and crystalline silicon solar cells contact is not in the same one side of crystalline silicon solar cells, the carrier bar both ends link firmly with the connecting rod. Compare with traditional quartz boat, the utility model discloses reduced withthe silicon chip contact point, and further reduced area of contact on every contact point, reduced by a wide margin in the battery piece that to put the EL who results in unusually bad because of the quartz boat trench. 本实用新型涉及种用于晶体硅太阳能电池管式扩散的石英舟，包括若干连接杆和若干承载杆，其中承载杆的数量大于等于三；晶体硅太阳能电池插入至少三个承载杆的凹槽内，且凹槽与晶体硅太阳能电池接触的位置不在晶体硅太阳能电池同侧；承载杆两端与连接杆固连。与传统石英舟相比，本实用新型减少了与硅片接触点，且在每个接触点上进步减小了接触面积，大幅降低了电池片中因石英舟槽位置异常导致的EL不良。
