Irradiation-induced molecular dipole reorientation in inverted polymer solar cell using small molecular electron collection layer
Zai-Quan Xu, Fu-Zhou Sun, Jian Li, Shuit-Tong Lee, Yan-Qing Li, and Jian-Xin Tang
Inverted polymer solar cell is developed using small molecular tris(8-hydroxyquinolinato) aluminum (Alq3) as an electron collection layer between the active layer and indium-tin-oxide bottom cathode.
Near-infrared absorbing semitransparent organic solar cells
Jan Meiss, Felix Holzmueller, Roland Gresser, Karl Leo, and Moritz Riede
The devices employ an indium tin oxide-free top contact, consisting of thin metal films and an additional organic capping layer for enhanced light in/outcoupling. The solar cell encorporates a bulk heterojunction with the donor material Ph2-benz-bodipy, an infrared absorber.
Transparent, near-infrared organic photovoltaic solar cells for window and energy-scavenging applications
Richard R. Lunt and Vladimir Bulovic
Near-infrared absorbing organic photovoltaics are fabricated that are highly transparent to visible light. By optimizing near-infrared optical-interference, power efficiencies of 1.3±0.1% are demonstrated with simultaneous average visible transmission of >65%. A series-integrated array of these transparent cells is capable of powering electronic devices under near-ambient lighting. This architecture suggests strategies for high-efficiency power-generating windows and highlights an application uniquely benefiting from excitonic electronics. Featured in the New York Times.
Announcements
In Memoriam: Jules Routbort
We are saddened to report the sudden passing of APL Senior Associate Editor, Jules L. Routbort. Dr. Routbort joined the Journal as an Associate Editor in 1992, and became Senior Associate Editor in 2008, in concurrence with his regular research work as a Senior Scientist at Argonne National Laboratory. In his 20-year dedicated service to the Journal, he efficiently shepherded thousands of submitted papers through the peer-review system and constantly strived to maintain high standards of APL publications. His judgment was always fair and firm. The American Institute of Physics joins the entire APL community in honoring Dr. Routbort’s legacy of excellence.
- AIP joins the entire scientific community in congratulating Saul Perlmutter, Brian P. Schmidt, and Adam G. Riess on winning the 2011 Nobel Prize in Physics and Daniel Shechtman for his Nobel Prize in chemistry. The award in physics was for the groundbreaking discovery of the accelerating expansion of the universe through observations of distant supernovae. Dr. Shechtman’s award in chemistry was for his discovery of quasicrystals. See AIP Journal papers by the 2011 Nobel Laureates—FREE through the end of the year.
- Professor Minn-Tsong Lin joins Applied Physics Letters as new Associate Editor.
- Congratulations to Michal Lipson, APL author, recipient of the 2010 MacArthur Fellows grant.
- Congratulations to elected 2010 Neutron Scattering Society of America Fellow, Associate Editor, David L. Price
