Organics Semiconductors

Organic electronics has recently emerged as a low cost alternative to conventional electronics.

Organic electronics can be developed on flexible substrates, realizing both active devices (Organic Thin-Film Transistors, OTFTs) and optoelectronic devices (Organic Light-Emitting Diodes, OLEDs, and Organic Solar Cells, OSCs).

There are many applications where the performances of organic electronics are already sufficient, including large-area sensors, displays, and circuit applications (for OTFTs), portable devices, car dashboards and televisions (for OLEDs), and calculators, thermometers, clocks and price tags (for OSCs). However, the performance and the lifetime of organic electronic devices are still below the specifications imposed by the market.

You find here a brief overview of our research areas on organic electronics. The research activity include electronic and optoelectronic devices, from the organic thin film transistor, to the organic LED and organic photovoltaics.

Organic TFTs

Stability and Reliability are the key-issues for Organic TFT. Among our focus there are the analysis of charge-trapping phenomena, the study of the role of self-heating in determining devices degradation, the 2D simulation of devices characteristics.

Organic LEDs

Our primary focus are: electro-optical characterization of the performance of the devices, modeling of the thermal behavior of the samples by finite-element methods, capacitive investigation of the technological parameters of the devices, analysis of the effect of temperature on the characteristics of the devices, dc-stress tests and reliability analysis, failure analysis aimed at identifying degradation modes.

Organic Solar Cells

Our primary goals are the characterization of the efficiency of cells, the analysis of the dependence of the main devices parameters (e.g., efficiency, fill factor, short-circuit current and open circuit voltage) on temperature and illumination conditions, the study of the reliability of the devices and of its dependence on stress temperature and illumination level.
