Organic photovoltaics
In the last ten years, the highest efficiency obtained from organic photovoltaics (OPVs), such as bulk heterojunction polymer:fullerene solar cells, has risen from 2.5 to 11 %. This rapid progress suggests that the commercialization of OPVs should be realized soon if we can solve some technical issues. The advances in the development of OPVs can be attributed to four fronts: (i) a better unders...
متن کاملOrganic photovoltaics and concentrators
The separation of light harvesting and charge generation offers several advantages in the design of organic photovoltaics and organic solar concentrators for the ultimate end goal of achieving a lower cost solar electric conversion. In this work, we explore two new device architectures. In antenna organic solar cells, we utilize external energy transfer mediated by surface plasmon polaritons to...
متن کاملOrganic Photovoltaics Interdigitated on the Molecular Scale
Phosphonated porphyrin frameworks that are porous to an electron-accepting perylenediimide are systematically interdigitated with a phosphonated form of the diimide to form bulk heterojunctions. When employed in photovoltaics, these molecularly interlaced heterojunctions provide large junction areas while retaining the phase connectivity of traditional bilayer heterojunctions. Zirconium phospho...
متن کاملOrganic photovoltaics: technology and market
Organic photovoltaics has come into the international research focus during the past three years. Up to now main efforts have focused on the improvement of the solar conversion efficiency, and in recent efforts 5% white light efficiencies on the device level have been realized. Despite this in comparison to inorganic technologies low efficiency, organic photovoltaics is evaluated as one of the ...
متن کاملFocus on organic electronics
1 Purdue University, USA Hosei University, Japan E-mail: [email protected] and [email protected] Electronically active materials, once largely the domain of inorganic metals and semiconductors, have become increasingly organic in character. Contemporary electronic materials such as light-emitting device (LED) displays, photovoltaic cells, and thin-film transistors (TFTs) all feature organic mo...
