Abstract

Currently, the field of organic photovoltaics experiences tremendous growth because this technology offers competitive efficiency of light – to – energy conversion and compliance with requirements for high-throughput manufacturing (roll – to – roll, screen printing, etc.). However, several challenges exist, such as relatively short device lifetime and optimization of device structure to achieve a commercial viability threshold of 10% power conversion efficiency for this technology, exist. For research purposes quick, simple and inexpensive approaches for device encapsulation are desired for high-throughput screening of samples. In this paper we show that encapsulation of organic photovoltaic devices using silicone adhesive and Kapton or glass is a viable approach for preserving devices in ambient conditions at ~25 °C in the dark for at least 24 hours. Also, PET, Kapton and glass encapsulation materials can be used to limit oxygen and water access to the device and to determine prevalent degradation pathways in organic solar cells.
