The purpose of this paper is to investigate the behavior of interconnections between solar cells in a glass-free solar modules. As glass weight can be a limitation, it is still interesting to investigate other types of systems, especially when the glass was replaced with a polymeric front sheet. Such systems can be more sensitive for the solar cell interconnection ribbon fatigue.,To examine this effect, the set of glass-based and glass-free modules were prepared using various ribbon thickness and treatment concerning its stretching or curving before lamination. Furthermore, additional reinforcement of the connection between the ribbon and the solar cell was proposed. The prepared modules were exposed to the cyclic temperature variation in the environment chamber. The number of cycles after which the interconnection maintains its conductivity was noted.,Changing the outer layers into more elastic ones requires additional care for the ribbon treatment because interconnections become more sensitive for a system relative displacement. To secure interconnection before fatigue an additional curving of ribbon between solar cells can be introduced whereas the best results were obtained for a system with aluminum plate laminated as an interlayer.,The paper presents a new system of a glass-free solar module based on epoxy-glass fiber composite as a backsheet. The glass front sheet was replaced with an elastic, transparent polymer. Such construction can be used in a system where the glass weight is a limitation. As glass has a structural function in traditional modules and limits fatigues of interconnections the proposed system requires additional ribbon treatment to preserve long module life-span.

带状处理对无玻璃光伏组件内太阳能电池互连的影响

本文的目的是研究无玻璃太阳能模块中太阳能电池之间互连的行为。由于玻璃重量可能是一个限制因素，因此研究其他类型的系统仍然很有趣，尤其是当玻璃被聚合物前板取代时。这种系统对太阳能电池互连带疲劳更敏感。为了检查这种影响，使用各种带厚度和层压前有关其拉伸或弯曲的处理来制备玻璃基和无玻璃模块组。此外，还提出了对带和太阳能电池之间连接的额外加强。准备好的模块暴露在环境室中的循环温度变化中。注意到互连保持其导电性后的循环次数。将外层改变为更具弹性的外层需要额外注意带处理，因为互连对系统相对位移变得更加敏感。为了在疲劳之前确保互连，可以在太阳能电池之间引入额外的带状弯曲，而使用层压铝板作为夹层的系统获得了最佳结果。本文提出了一种基于环氧树脂的无玻璃太阳能模块新系统-玻璃纤维复合材料作为背板。玻璃前板被一种弹性的、透明的聚合物所取代。这种结构可用于玻璃重量受到限制的系统中。
