Summary:Long term stability is critical for maturing any photovoltaic (PV) technology. Understanding the environmental impact on the PV cell performance is crucial to assess its reliability. In this work, an accelerated test methodology has been developed for evaluating an unencapsulated flexible PV cell performance. A semi-empirical model has been developed and validated, which enabled predicting the flexible PV cell life under typical factory environmental conditions. This framework can be used as a guideline for defining appropriate storage conditions for PV cell to avoid unintended degradation before laminating the cell to a module.
