Description
技术领域Technical field
本发明涉及太阳能电池技术领域，具体的，涉及钝化叠层电池及其制备方法。The present invention relates to the technical field of solar cells, and specifically to passivated stacked cells and preparation methods thereof.
背景技术Background technique
叠层太阳能电池是指使用不同带隙的太阳能电池串联而成，结构相对简单，可以提高太阳能电池的光电转换效率。两端叠层电池与目前产业化电池结构一致，与四端叠层电池结构对比，制备成电站等走向产业化应用时无需额外增加逆变器等设备，可以与产业化工艺兼容，因此成为主要研究对象。两端叠层电池中，钙钛矿/晶硅两端叠层电池是在硅电池上直接生长钙钛矿电池，中间通过复合层连接两个子电池，实现串联结构，钙钛矿/晶硅两端叠层电池已实现32.5％的认证效率，进一步证明了这种结构电池的巨大潜力。Tandem solar cells refer to solar cells with different band gaps connected in series. The structure is relatively simple and can improve the photoelectric conversion efficiency of solar cells. The structure of two-terminal laminated batteries is consistent with the current industrial battery structure. Compared with the structure of four-terminal laminated batteries, there is no need to add additional equipment such as inverters when being prepared into industrial applications such as power stations. It is compatible with industrial processes, so it has become the main Research object. Among the two-terminal stacked cells, the perovskite/crystalline silicon two-terminal stacked cell is a perovskite cell grown directly on the silicon cell, and the two sub-cells are connected through a composite layer in the middle to achieve a series structure. The perovskite/crystalline silicon two-terminal stacked cell The terminal stacked cell has achieved a certified efficiency of 32.5%, further proving the huge potential of this structural cell.
然而由两种不同半导体材料制成的叠层电池的侧边缺陷严重影响了电池效率的进一步提升。现有的钝化技术如SiO2钝化、a-Si:H钝化、SiNx钝化或Al2O3钝化，均与目前钙钛矿/晶体硅叠层电池工艺不兼容。即对一个子电池进行钝化时，可能需要对另一个子电池进行掩膜保护以避免电池被钝化材料污染，并且在对晶硅电池进行钝化时需要的高温工艺会破坏钙钛矿电池结构，因此现有技术对叠层电池的钝化较为困难。However, the side defects of stacked cells made of two different semiconductor materials seriously affect the further improvement of cell efficiency. Existing passivation technologies such as SiO2 passivation, a-Si:H passivation, SiNx passivation or Al2O3 passivation are incompatible with the current perovskite/crystalline silicon stacked cell process. That is, when passivating one sub-cell, the other sub-cell may need to be protected by a mask to avoid contamination of the cell by the passivation material, and the high-temperature process required when passivating a crystalline silicon cell will damage the perovskite cell. structure, so it is difficult to passivate tandem batteries with the existing technology.

如图1所示，钝化叠层电池，包括相互串联且叠层设置的第一电池组1和第二电池组2，用于将照射到第一电池组1和第二电池组2的受光面上的光转化为电能并输出；As shown in Figure 1, the passivated stacked battery includes a first battery group 1 and a second battery group 2 that are connected in series and arranged in a stack, and are used to receive light irradiated to the first battery group 1 and the second battery group 2. The light on the surface is converted into electrical energy and output;
第一电池组1包括一个钙钛矿电池子电池，第二电池组2包括一个硅电池子电池；The first battery pack 1 includes a perovskite cell sub-cell, and the second battery pack 2 includes a silicon cell sub-cell;
第一电池组1的侧面、第二电池组2的侧面、第二电池组2与第一电池组1叠层接触时的露出面5上均设置有第一钝化层3，第一钝化层3的材料包括有机钝化材料；A first passivation layer 3 is provided on the side of the first battery pack 1, the side of the second battery pack 2, and the exposed surface 5 when the second battery pack 2 is in stacked contact with the first battery pack 1. The material of layer 3 includes organic passivation material;
首先，在第一电池组1的侧面、第二电池组2的侧面以及露出面5上均设置有第一钝化层3，在第一电池组1的侧面、第二电池组2的侧面以及露出面5上形成偶极子有序排列，取向一致，形成极化场，通过第一电池组1侧面和第二电池组2侧面的铁电极化场驱动少子远离第一电池组1侧面、第二电池组2侧面以及露出面5，从而实现钝化第一电池组1侧面、第二电池组2侧面和露出面5中悬挂键和缺陷态的目的，降低了第一电池组1侧面、第二电池组2侧面和露出面5的载流子复合，提升了光伏叠层电池的开路电压以及填充因子，进而提高了叠层电池的输出功率。First, the first passivation layer 3 is provided on the side of the first battery pack 1, the side of the second battery pack 2 and the exposed surface 5. Dipoles are formed on the exposed surface 5 and are arranged in an orderly manner with consistent orientations to form a polarization field. The ferroelectric polarization fields on the side of the first battery pack 1 and the side of the second battery pack 2 drive the minority carriers away from the side of the first battery pack 1 and the second battery pack 2. The side of the second battery pack 2 and the exposed surface 5 are used to passivate the dangling bonds and defective states in the side of the first battery pack 1, the side of the second battery pack 2 and the exposed surface 5, thereby reducing the risk of the side of the first battery pack 1 and the exposed surface 5. The carrier recombination on the side of the second battery pack 2 and the exposed surface 5 increases the open circuit voltage and fill factor of the photovoltaic stacked cell, thereby increasing the output power of the stacked cell.
其次，由于第一电池组1的侧面、第二电池组2的侧面以及露出面5均设置有第一钝化层3，在对第一电池组1的侧面进行钝化时，不需要第二电池组2的侧面以及露出面5进行掩膜保护以避免电池被钝化材料污染，从而使得钝化工艺更加简单，成本低廉；Secondly, since the first passivation layer 3 is provided on the side of the first battery pack 1, the side of the second battery pack 2 and the exposed surface 5, no second passivation layer 3 is required when passivating the side of the first battery pack 1. The side of the battery pack 2 and the exposed surface 5 are protected by masks to prevent the batteries from being contaminated by passivation materials, thereby making the passivation process simpler and cheaper;
第三，在第二电池组2与第一电池组1叠层接触时的露出面5上设置第一钝化层3，避免了该露出面5因缺少透明电极保护而发生析氢现象进而减弱钝化效果的问题，减少了载流子的界面复合，从而提高了叠层电池效率。Third, the first passivation layer 3 is provided on the exposed surface 5 when the second battery pack 2 is in stacked contact with the first battery pack 1 to avoid hydrogen evolution on the exposed surface 5 due to the lack of transparent electrode protection and thus weaken passivation. The problem of the chemical effect is reduced, and the interface recombination of carriers is reduced, thereby improving the efficiency of the stacked battery.
第四，第一钝化层3的材料包括有机钝化材料，有机钝化材料可通过溶液化制备涂覆在第一电池组1的侧面、第二电池组2的侧面以及露出面5上，形成第一钝化层3，该钝化过程在常温常压下进行，无需高温高压真空，避免了钝化过程对叠层电池结构的破坏，从而提高了叠层电池效率。Fourth, the material of the first passivation layer 3 includes an organic passivation material. The organic passivation material can be prepared by solution and coated on the side of the first battery pack 1, the side of the second battery pack 2 and the exposed surface 5, The first passivation layer 3 is formed.

The second passivation layer 4 is in contact with the electrode electrode. The connection reduces the interface recombination with the electrode and increases the current collection effect, thereby further improving the efficiency of the stacked battery. At the same time, electrical conduction can be achieved without opening holes in the passivation layer, and the passivation method is simple.
光照射到电池上时，会产生光生少数载流子(简称少子)，少子包括电子和空穴，电池的前后表面缺陷、侧面缺陷还有体缺陷越少，少子与缺陷复合越少，并且前后表面缺陷越少，电池的开路电压和填充因子越高，少子前后表面复合速率越小，少子寿命越长，则电池收集到的光生少子越多，效率越高，有效少子寿命的计算公式如下：When light irradiates the battery, photogenerated minority carriers (minority carriers for short) will be generated. Minority carriers include electrons and holes. The fewer front and rear surface defects, side defects and body defects of the battery, the fewer minority carriers will recombine with defects, and the front and rear surface defects will be smaller. The fewer surface defects, the higher the open circuit voltage and filling factor of the battery, the smaller the surface recombination rate before and after the minority carrier, and the longer the minority carrier lifetime. The battery collects more photogenerated minority carriers and has higher efficiency. The calculation formula for the effective minority carrier lifetime is as follows:
上式中，τeff为有效少子寿命，τbulk为电池的体少子寿命，τl为电池的侧面少子寿命，W为电池的厚度，Sf和Sb分别为电池的前表面复合速率和后表面复合速率。In the above formula, τeff is the effective minority carrier lifetime, τbulk is the bulk minority carrier lifetime of the battery, τl is the side minority carrier lifetime of the battery, W is the thickness of the battery, Sf and Sb are the front surface recombination rate and rear surface recombination rate of the battery respectively.
本实施例中，对叠层电池的侧面、露出面5、上下表面等处缺陷进行钝化，减小了前表面复合速率Sf、后表面复合速率Sb，增大了侧面少子寿命τl，通过上述有效少子寿命公式可知，叠层电池的有效少子寿命、开路电压、填充因子和效率均会增大。In this embodiment, defects on the side, exposed surface 5, upper and lower surfaces of the laminated battery are passivated, reducing the front surface recombination rate Sf and the rear surface recombination rate Sb, and increasing the side minority carrier lifetime τl. Through the above The effective minority carrier lifetime formula shows that the effective minority carrier lifetime, open circuit voltage, fill factor and efficiency of the stacked battery will all increase.
因此，本实施例中钝化了叠层电池的侧面、露出面5、上下表面等处缺陷，提高了叠层电池的开路电压、填充因子和效率等，该叠层电池的制备方法操作简单，且形成的钝化层均匀一致，可以实现工业化大批量制备。Therefore, in this embodiment, defects on the side, exposed surface 5, upper and lower surfaces of the stacked battery are passivated, and the open circuit voltage, filling factor and efficiency of the stacked battery are improved.
