“…Organic materials are following similar history to amorphous semiconductors, where the practical applications were growing faster than the development of theoretical physics of the materials. In [31], the temperature dependence of DC conductivity of spin-coated poly PEDOT:PSS films has been investigated, σ DC (T) was measured in films deposited from different mixtures of PEDOT:PSS (Figure 4). Experimental data was fitted with two different transport models: thermal activated conduction and variable range hopping (VRH) model.…”

The concept for inorganic-organic device is an attractive technology to develop devices with better characteristics and functionality due to the complementary advantages of inorganic and organic materials. This chapter provides an overview of the principal requirements for organic and inorganic semiconductor properties and their fabrication processes and focus on the compatibility between low temperature plasma enhanced chemical vapor deposition (PECVD) and polymer organic materials deposition. The concept for inorganic-organic device was validated with the fabrication of three hybrid thin film photovoltaic structures, based on hydrogenated silicon (Si:H), organic poly(3-hexythiophene): methano-fullerenephenyl-C61-butyric-acid-methyl-ester (P3HT:PCBM), and poly(3,4 ethylenedioxythiophene): poly(4-styrenesulfonate) (PEDOT:PSS) films. Optoelectronic characteristics, performance characteristics, and interfaces of the different configurations aspects are discussed. Hybrid ITO/PEDOT:PSS/(i)Si:H/(n)Si:H structure results in a remarkably high short circuit current density as large as 17.74 mA/cm 2 , which is higher than the values in organic or inorganic reference samples. Although some hybrid structures demonstrated substantial improvement of performance, other hybrid structures showed poor performance, further R&D efforts seem to be promising, and should be focused on deeper study of organic materials and related interface properties.

“…In the field of pure organic solar cell technology, it is well known that the characteristics of PEDOT:PSS should be modified by applying physical or chemical postdeposition treatments in order to tailor characteristics according to the function of the conducting polymer [18,19,20]. For example, the dark conductivity of PEDOT:PSS films can be modified by orders of magnitude via solvent treatment [21,22]. Using this concept, our group in 2017 [23] has previously reported the influence of post-treatment on PEDOT:PSS/a-Si:H interface in solar cells.…”

In this work, we propose poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) material to form a hybrid heterojunction with amorphous silicon-based materials for high charge carrier collection at the frontal interface of solar cells. The nanostructural characteristics of PEDOT:PSS layers were modified using post-treatment techniques via isopropyl alcohol (IPA). Atomic force microscopy (AFM), Fourier-transform infrared (FTIR), and Raman spectroscopy demonstrated conformational changes and nanostructural reorganization in the surface of the polymer in order to tailor hybrid interface to be used in the heterojunctions of inorganic solar cells. To prove this concept, hybrid polymer/amorphous silicon solar cells were fabricated. The hybrid PEDOT:PSS/buffer/a-Si:H heterojunction demonstrated high transmittance, reduction of electron diffusion, and enhancement of the internal electric field. Although the structure was a planar superstrate-type configuration and the PEDOT:PSS layer was exposed to glow discharge, the hybrid solar cell reached high efficiency compared to that in similar hybrid solar cells with substrate-type configuration and that in textured well-optimized amorphous silicon solar cells fabricated at low temperature. Thus, we demonstrate that PEDOT:PSS is fully tailored and compatible material with plasma processes and can be a substitute for inorganic p-type layers in inorganic solar cells and related devices with improvement of performance and simplification of fabrication process.

“…The observed effect is, of course, a cumulative effect, reflecting possible changes either in the bulk or at the electrodes. With regard to the electrodes' contribution, the observed phenomenon can be explained by considering the low level of conductivity associated with the PEDOT:PSS electrodes [21]. Nevertheless, further investigation is needed to determine any contribution of the bulk to the decrement of the resulting resistance.…”

The need for a sustainable economy necessitates new environmentally friendly production technologies as well as devices that can be easily recycled, disposed of, and, finally, degraded, without any release of pollutants to the environment. In this context, bacterial cellulose (BC) has recently been investigated as an intriguing solution for the creation of green motion sensors. BC has excellent mechanical properties, and it is fully biodegradable and greener than the more common plant-derived cellulose. In this paper, we investigate the influence of geometry and environmental temperature on BC based sensing elements. More specifically, the influence of these quantities on a previously investigated BC-based accelerometer are reported. An experimental campaign and the characterization of the proposed green device for several geometries (from 7 to 22 mm of length) and various temperatures (from 5 °C to 55 °C) is addressed, obtaining very intriguing results.
