This paper presents a study on the effects of heat treatment conditions on electrically conductive adhesives. Among the advantages of the shingled solar cells include larger active area and smaller current density since one of the main factors of the power loss is due to a decrease in current density. Therefore, when there is a small current, there is a benefit in regards to the power loss. The advantage of this new technique of developing photovoltaic modules is the increase of module power using the same installed area. Electrically conductive adhesives play an important role in the manufacture of shingled solar cells and understanding the effects of its curing condition is necessary to maximize its output power. Through changing the curing time and temperature, the optimized curing conditions for electrically conductive adhesives and fabricated shingled strings for development of a module could be established. Finally, we demonstrated a 500 mm × 500 mm photovoltaic module with a conventional and the other using the shingled method for purposes of comparison and a shingled module showed about 29% increase in maximum output power compared to a conventional module with the same installed area.
本文介绍了一项关于热处理条件对导电胶影响的研究。叠瓦式太阳能电池的优点之一包括有效面积更大和电流密度更小，因为功率损耗的主要因素之一是电流密度的降低。因此，当电流较小时，在功率损耗方面是有益的。这种开发光伏组件的新技术的优点是在相同的安装面积下提高了组件功率。导电胶在叠瓦式太阳能电池的制造中起着重要作用，了解其固化条件对于最大化其输出功率是必要的。通过改变固化时间和温度，可以建立导电胶的优化固化条件以及用于组件开发的叠瓦式串。最后，为了进行比较，我们展示了一个500毫米×500毫米的光伏组件，一个采用传统方法，另一个采用叠瓦式方法，与相同安装面积的传统组件相比，叠瓦式组件的最大输出功率提高了约29%。
