Interface engineering of a highly sensitive solution processed organic photodiode

Interface engineering of a highly sensitive solution processed organic photodiode.

We report on tuning of the interfacial properties of a highly sensitive organic photodiode by introducing a buffer layer between the anode and the semiconductor layer. The effects of different buffer layers consisting of a self-assembled monolayer (SAM), PEDOT:PSS, and pentacene on the morphology and crystallinity of the upper-deposited bulk heterojunction semiconductor layer are carefully anal...

Interface Engineering for Organic Electronics

Solution-processed new porphyrin-based small molecules as electron donors for highly efficient organic photovoltaics.

A series of unsymmetrical π-conjugated small molecules have been constructed from meso-alkyl substituted porphyrins as the central unit and 3-ethylrhodanine as the terminal group. Using PC71BM as an acceptor, and these small molecules as electron donors in solution-processed bulk-heterojunction solar cells, a high power conversion efficiency of 6.49% has been achieved.

Device Physics of Solution-Processed Organic Field-Effect Transistors

Following the initial demonstration of field-effect conduction in small organic molecules and conjugated polymers, the community of industrial and academic research groups that are interested in using organic semiconductors as the active layer in organic field-effect transistor (OFET) devices has been growing steadily, particularly over the last four to five years. The Institute for Scientific ...

Controllable lasing performance in solution-processed organic-inorganic hybrid perovskites.

Solution-processed organic-inorganic perovskites are fascinating due to their remarkable photo-conversion efficiency and great potential in the cost-effective, versatile and large-scale manufacturing of optoelectronic devices. In this paper, we demonstrate that the perovskite nanocrystal sizes can be simply controlled by manipulating the precursor solution concentrations in a two-step sequentia...
