TL;DR: Bulk heterojunction engineering tunes optoelectronic properties of ambipolar organic light-emitting transistors. The electron and hole mobilities, as well as the electroluminescence intensity, can be tuned over a large range by changing the composition of a bimolecular mixture.
Ambipolar light-emitting organic field-effect transistor
Constance Rost,Siegfried Karg,Walter Riess,Maria Antonietta Loi,Mauro Murgia,Michele Muccini +5 more
TL;DR: In this article, a light-emitting organic field effect transistor (OFET) with pronounced ambipolar current characteristics is demonstrated, where the light intensity is controlled by both the drain-source voltage VDS and the gate voltage VG.
Tuning Optoelectronic Properties of Ambipolar Organic Light-Emitting Transistors Using a Bulk-Heterojunction Approach
Maria Antonietta Loi,Constance Rost-Bietsch,Mauro Murgia,Siegfried Karg,Walter Riess,Michele Muccini +5 more
TL;DR: In this article, a bulk-heterojunction approach was used to select and tailor the functionality of field-effect devices, including ambipolar charge transport and light emission, and phase segregation of the two molecules in the bulk heterojunction and their electronic interaction determined the optoelectronic properties of the devices.
Photoluminescence Enhancement in Formamidinium Lead Iodide Thin Films
TL;DR: In this paper, the light-induced photoluminescence (PL) evolution in FAPbI(3) thin films is investigated, and it is found that the PL intensity evolution is strongly dependent on the atmosphere surrounding the samples.
Efficient Perovskite Solar Cells over a Broad Temperature Window: The Role of the Charge Carrier Extraction
Shuyan Shao,Jian Liu,Hong-Hua Fang,Li Qiu,Gert H. ten Brink,Jan C. Hummelen,L. Jan Anton Koster,Maria Antonietta Loi +7 more
TL;DR: In this paper, the authors investigated the mechanism behind the temperature dependence of the device performance in hybrid perovskite solar cells (HPSCs) and found that the deteriorated charge carrier extraction is the dominant factor causing this degradation.
