Abstract New technologies to fabricate high-output power photovoltaic (PV) modules include a cell dividing and bonding technique. This technique divides and interconnects cells into a string arranged in series and in parallel to produce a module. Therefore, we designed a 3–6 dividing front electrode structure that is suitable for the shingled module. Thus, power loss was calculated based on the number of cell divisions and the number of fingers. The simulation results indicated that increases in the number of cells to be divided decreased the number of fingers exhibiting the maximum efficiency. The number of fingers optimized for division in to 5 cells was 128. Additionally, the power conversion efficiency was 17.346%, and this corresponded to the highest efficiency among various electrode structures for division from three to six solar cells. The optimized finger number for division into 3 cells was 171, and this corresponded to the lowest efficiency of 16.855%. The multi-crystalline silicon solar cells exhibiting a finger number of 100 were fabricated to compare with the simulation results. We analyzed the characteristics and obtained results that were nearly similar to those of the simulation. For application to a shingled module, a solar cell with an appropriate electrode structure was divided into 5 cells via the laser scribing system, subsequently bonded with an electrically conductive adhesive (ECA), and the characteristics were analyzed.

用于叠瓦式光伏组件应用的太阳能电池电极的设计

摘要 制造高输出功率光伏（PV）模块的新技术包括电池分割和粘合技术。这种技术将电池划分并互连成串联和并联排列的串以生产模块。因此，我们设计了一种适用于叠瓦式模块的 3-6 分割前电极结构。因此，基于细胞分裂的数量和指的数量计算功率损失。模拟结果表明，增加被分割的单元数量会减少表现出最大效率的指状件的数量。为划分为5个电池而优化的手指数为128个。此外，功率转换效率为17.346%，这对应于从三个到六个太阳能电池划分的各种电极结构中的最高效率。划分为 3 个细胞的优化指数为 171，这对应于 16.855% 的最低效率。制造手指数为 100 的多晶硅太阳能电池以与模拟结果进行比较。我们分析了特性并获得了与模拟几乎相似的结果。为了应用于叠瓦模块，通过激光划线系统将具有适当电极结构的太阳能电池分成 5 个电池，然后用导电粘合剂 (ECA) 粘合，并分析其特性。制造手指数为 100 的多晶硅太阳能电池以与模拟结果进行比较。我们分析了特性并获得了与模拟几乎相似的结果。为了应用于叠瓦模块，通过激光划线系统将具有适当电极结构的太阳能电池分成 5 个电池，然后用导电粘合剂 (ECA) 粘合，并分析其特性。制造手指数为 100 的多晶硅太阳能电池以与模拟结果进行比较。我们分析了特性并获得了与模拟几乎相似的结果。为了应用于叠瓦模块，通过激光划线系统将具有适当电极结构的太阳能电池分成 5 个电池，然后用导电粘合剂 (ECA) 粘合，并分析其特性。
