Journal ArticleDOI
Light-trapping nano-structures in organic photovoltaic cells
Doo-Hyun Ko,John R. Tumbleston,Abay Gadisa,Mukti Aryal,Yingchi Liu,Rene Lopez,Edward T. Samulski +6 more
TL;DR: In this article, a review of nano-structures used as light trapping schemes in organic photovoltaic (OPV) cells is presented, where surface plasmons, anti-reflection coatings, and photonic crystal patterns are used.
Journal ArticleDOI
Alkyl‐Chain‐Length‐Independent Hole Mobility via Morphological Control with Poly(3‐alkylthiophene) Nanofibers
Wibren D. Oosterbaan,Jean-Christophe Bolsée,Abay Gadisa,Veerle Vrindts,Sabine Bertho,Jan D'Haen,Thomas J. Cleij,Laurence Lutsen,Christopher R. McNeill,Lars Thomsen,Jean Manca,Jean Manca,Dirk Vanderzande,Dirk Vanderzande +13 more
TL;DR: In this paper, the field effect transistor (FET) and diode characteristics of poly(3-alkylthiophene) (P3AT) layers deposited from nanofiber dispersions are presented and compared with those of layers from molecularly dissolved polymer solutions in chlorobenzene.
Journal ArticleDOI
High Performance Organic Solar Cells Processed by Blade Coating in Air from a Benign Food Additive Solution
Long Ye,Yuan Xiong,Huifeng Yao,Abay Gadisa,Hao Zhang,Sunsun Li,Masoud Ghasemi,Nrup Balar,Adrian Hunt,Brendan O'Connor,Jianhui Hou,Harald Ade +11 more
TL;DR: In this paper, the potential of o-methylanisole as a certified food additive as a processing solvent for organic photovoltaics in spin-casted films was investigated.
Journal ArticleDOI
Transparent polymer cathode for organic photovoltaic devices
Abay Gadisa,Kristofer Tvingstedt,Shimelis Admassie,Linda Lindell,Xavier Crispin,Mats Andersson,Mats Andersson,William R. Salaneck,Olle Inganäs +8 more
TL;DR: A prototype solar cell with a transparent polymer cathode and an ITO/poly(3,4-ethylene dioxythiophene)-poly(styrene sulfonate) (PEDOT:PSS) anode was fabricated in this paper.
Journal ArticleDOI
Panchromatic Sequentially Cast Ternary Polymer Solar Cells.
Masoud Ghasemi,Long Ye,Qianqian Zhang,Liang Yan,Joo-Hyun Kim,Omar Awartani,Wei You,Abay Gadisa,Harald Ade +8 more
TL;DR: A sequential-casting ternary method is developed to create stratified bulk heterojunction (BHJ) solar cells, in which the two BHJ layers are spin cast sequentially without the need of adopting a middle electrode and orthogonal solvents.
