You are correct that polymer solar cells can degrade because of contact with oxygen and moisture from the air (coupled with heat). Further, ultraviolet light tends to degrade polymer chains. However, some polymers are more resistant than others. Hence the use of an encapsulant to protect them. I have seen literature discussing the use of materials in the encapsulant that can absorb the UV and re-emit it as visible light.
The questions are: Is the Renology panel resistant to UV and O2 degradation. What is the warranted life of the panel?
In general, it is my understanding that flexible solar panels have a shorter life (around 10 years) than traditional Si/Glass solar panels.(20 years or more). Also, the efficiency of flexible solar panels is less than traditional solar panels, so for an equivalent output the flexible panels need more area.
Seems like Renology should know the answer to these basic questions about the materials they use. Would be great if they would disclose the the whole stack up of materials including adhesives and sealants. Knowing that information one could look up the materials and their susceptability to degradation independently and be able to ask informed follow-up questions.
