Richard R. Lunt, Timothy P. Osedach, Patrick R. Brown, Jill A. Rowehl and Vladimir Bulović Practical Roadmap and Limits to Nanostructured Photovoltaics Advanced Materials 23
The practical efficiency limits for nanostructured photovoltaics including organic small molecule, dye-sensitized, polymer, and colloidal-quantum-dot architectures estimated a posteriori are assessed. The specific challenges associated with improving the electrical power conversion efficiency of various nanostructured photovoltaic (nano-PV) technologies are discussed and several approaches to reduce their thermal losses beyond the single bandgap limit are reviewed. Critical considerations related to the module lifetime and cost that are unique to nano-PV architectures are also discussed.
