Definitions
- the invention relates to an aluminum paste for a crystalline silicon solar cell, in particular to an aluminum paste for an all-aluminum back field crystalline silicon solar cell and a preparation method thereof.
- a solar cell is a semiconductor device that converts solar energy into electrical energy. Under the illumination condition, a photo-generated current is generated inside the solar cell, and the current can be output through the electrode.
- the commercial crystalline silicon battery is still based on conventional batteries, the process flow is relatively simple, the manufacturing cost is relatively low, and the cost performance is high, but the conventional battery has the following defects, mainly that the back electrode is directly printed on the silicon wafer to form an ohmic contact, silver
- the electrode is easy to form metal defects in the silicon wafer, which makes the electrode become a serious leakage area, which reduces the photoelectric conversion efficiency of the solar cell; the back electrode edge needs to be covered by the aluminum back field, the back electrode width is increased, and the back electrode paste is added.
- the cost is not conducive to the improvement of photoelectric conversion efficiency.
- the patent provides an aluminum paste for an all-aluminum back field crystalline silicon solar cell and a preparation method thereof.
- Chinese Patent Application No. [201110208995.7] discloses a back field pole of a crystalline silicon battery and a printing process thereof. The process mainly prints an aluminum back field on the back side of the silicon wafer, and then prints the back electrode, which can better solve the problem.
- the deficiencies of the prior art can improve the photoelectric conversion efficiency of the crystalline silicon battery.
- This patent mainly describes the preparation process of the all-aluminum back field, and does not describe the preparation method of the aluminum paste and the back-pole paste for the all-aluminum back-field crystalline silicon solar cell.
- Chinese patent [CN103151097A] discloses a preparation method of slurry for all-aluminum back field of crystalline silicon battery
- the invention relates to a method for preparing a back-electrode slurry for a full-aluminum back field of a crystalline silicon battery, in which a low melting point coated base metal is added, wherein the coating is tin or silver, and is coated.
- the coating is one or more of the base metals.
- the silver powder and the aluminum back field can form a good sintered intermediate layer, the expansion coefficient is matched with the aluminum back field, and the turtle is not easy to be turtle.
- the patent mainly describes the back electrode slurry.
- Chinese patent [CN103746043A] discloses a preparation method of an all-aluminum doped solar cell, in particular to a method for preparing an N-type solar cell, firstly preparing an all-aluminum back field by using a full back-field screen without a back electrode pattern. After high temperature sintering, a good PN junction is formed; then the low temperature sintered silver paste is used as a slurry, and the back electrode is prepared by low temperature sintering, which overcomes the problem that the conventional silver aluminum paste back electrode can only be sintered at a high temperature, due to the back electrode.
- the sintering temperature is low, so that the sintering depth of the back electrode is less than the depth of aluminum diffusion, and does not affect the quality of the PN junction.
- the patent mainly describes a preparation method of all-aluminum back field doping of an N-type solar cell, which is compared with the conventional process. Compared with the process, the low-temperature sintering process is added, which conflicts with the production line, and the preparation method of the silver and aluminum paste for the all-aluminum back field is not specifically described. Similar patents also include [CN202996849U] and [CN102903765A].
- Cijögren's Patent [CN103219062A] discloses a method for preparing a polymer thick film solder alloy conductor composition, which relates to a solder alloy powder, which is composed of low melting point tin, silver and copper. It can be used in other applications where conductivity (low resistivity) is required, but the composition is not suitable for crystalline silicon solar cells.
- the object of the present invention is to mention only the silver paste for all-aluminum back field in the above solution.
- a method for preparing an all-aluminum back field crystalline silicon solar cell, and a method for preparing an aluminum paste for an all-aluminum back field and an improved process thereof, and providing an aluminum paste for an all-aluminum back field crystalline silicon solar cell The main characteristics of the aluminum paste are: changing the back aluminum formula on the basis of not changing the existing process, thereby improving the adhesion with the ordinary crystalline silicon solar cell silver paste, and effectively improving the photoelectric conversion efficiency of the crystalline silicon battery.
- an aluminum paste for an all-aluminum back field crystalline silicon solar cell comprising: 60-70% aluminum powder; 5-10% nano metal oil solution; - 10% inorganic binder; 10-20% organic binder; 5-30% organic solvent; 1-5% auxiliary; and the sum of the mass percentages of the components is 100%.
- the aluminum powder is a spherical aluminum powder having an average particle diameter of 0.8-10 ⁇ m, a purity of more than 99.8%, and a span of 2.0-4.0.

Description
本发明涉及晶体硅太阳能电池用铝浆,具体涉及一种全铝背场晶体硅太阳能电池用铝浆及其制备方法。
太阳能电池是一种能将太阳能转换成电能的半导体器件,在光照条件下太阳能电池内部会产生光生电流,通过电极可将电流输出。具有P型硅的太阳能电池结构,其负电极通常在电池的正面,而其正电极在背面。当光照射时,合适波长的辐射导致了半导体中产生空穴-电子对。在P-N结上存在的电势差使空穴和电子以相反的方向迁移穿过该结,从而产生了电流的流动,这种流动可将电能传递给外电路。目前商业化的晶体硅电池仍然以常规电池为主,工艺流程较为简单,制造成本较为低廉,性价比较高,但常规电池具有以下缺陷,主要是背电极直接印刷在硅片上形成欧姆接触,银电极易在硅片内形成金属缺陷,使电极成为严重的漏电区域,降低了太阳能电池的光电转换效率;背电极边缘需要被铝背场覆盖,增加了背电极宽度,增加了背电极浆料成本,不利于光电转换效率的提高。为解决该制作方式所产生的不足,提高晶硅太阳能电池的光电转换效率,本专利提供了一种全铝背场晶体硅太阳能电池用铝浆及其制备方法。
中国专利申请号[201110208995.7]公开了一种晶硅电池背场背极及其印刷工艺,该工艺主要是在硅片的背面先印刷铝背场,然后再印刷背电极,它可较好的解决现有技术的不足,可提高晶硅电池的光电转换效率。该专利主要讲述的是全铝背场的制备工艺,而未对全铝背场晶体硅太阳能电池用铝浆及背极浆料进行制备方法的说明。
中国专利[CN103151097A]公开了一种晶硅电池全铝背场用浆料的制备方
法,特别涉及一种晶体硅电池全铝背场用背极浆料的制备方法,该浆料中主要是添加了一种低熔点包覆贱金属,其中包覆物为锡或银,被包覆物为贱金属中的一种或几种,在改善全铝背场的背电极制备工艺的同时可使银粉与铝背场形成良好的烧结中间层、膨胀系数与铝背场匹配、不易龟裂及剥落、具有良好的导电性能,又能最大限度的保证浆料的欧姆接触性能和焊带的焊接性能,使全铝背场工艺得到了全面实施,该专利主要描述了背极浆料的改进与其工艺的完善,而未改变铝浆的特性,同时,这种背极浆料的成本较高,且未说明铝背场与银浆的附着情况,与本专利提出的改变铝浆有本质区别。
中国专利[CN103746043A]公开了一种全铝掺杂太阳能电池的制备方法,特别涉及一种N型太阳能电池的制备方法,首先采用不含背电极图形的全背场网版制备全铝背场,并经过高温烧结,形成良好的PN结;然后采用低温烧结银浆为浆料,经过低温烧结制备出背电极,克服了传统银铝浆背电极只能在高温下完成烧结的问题,由于背电极的烧结温度低,使得背电极的烧结深度小于铝扩散的深度,不会影响到PN结的质量,该专利主要描述一种N型太阳能电池全铝背场掺杂的制备方法,与传统工艺相比,该工艺添加了低温烧结工艺,与生产线有冲突,且未具体描述全铝背场专用银、铝浆的制备方法。相似专利还包括[CN202996849U]和[CN102903765A]。
中国专利[CN103219062A]公开了一种聚合物厚膜焊料合金导体组合物的制备方法,其中涉及一种焊料合金粉,该焊料合金粉由低熔点的锡、银、铜组成,制成的组合物可用于其它需要导电性(低电阻率)的应用,但是该组合物并不适用于晶体硅太阳能电池。
