Organic photovoltaics (OPV) is an emerging PV technology that shows potential for low-cost, light-weight, and flexible solar electricity generation. This highly interdisciplinary field has been of great academic and industrial interest. In the past few years, significant progress has been made with energy conversion efficiencies now in the 12% range in both polymeric and small molecule-based OPV devices. Despite this progress, there is still a need to increase our understanding of the underlying processes in OPV devices at the nanoscale and bulk as well as the chemistry, physics, and engineering issues behind OPV systems. Furthermore, the commercial viability of the technology such as large-area fabrication via roll-to-roll coating/printing or vacuum processes needs to be enabled to fully realize the advantages of OPV as a technology.

In ADRC, the research fields are mainly related with: 
i)          Polymeric, small molecule, and organic/inorganic hybrid PV devices
ii)         Novel interfacial/buffer layer materials
iii)         Active-layer materials development
iv)        Electrode strategies and materials development
v)         Novel device concepts and architectures
vi)        Lifetime issues and degradation mechanisms
vii)       Encapsulation materials and processes
