This work provides further insight on the long term stability, of Dye Sensitized Solar Cells (DSCs) assessed through prolong thermal aging at 85°C in dark. The investigation is focused on Bis(isothiocyanato)(4,4′-dicarboxylato-2,2′- bipyridine)(4,4′-dinonyl-2,2′-bipyridine)ruthenium(II) (Z907) sensitized devices employing commercially available ionic liquid electrolyte (livion 12, L12) with high boiling...
We present the use of covalently functionalized carbon nanostructures (CNSs) such as single-wall carbon nanotubes (SWCNTs) and graphene nanoplatelets (GNPs), as conductive nanofillers in a P3HT matrix. We propose a simple approach for the preparation of the active blends used as hole transport layer (HTL) in mesoporous perovskite solar cells (PSCs). We demonstrate that for both SWCNT and GNP nanofillers,...
In view of obtaining light-weight, wearable and low-cost supply systems for low power electronics, the integration of dye-sensitized solar cells (DSSCs) in portable devices represents an important target for the scientific community. Nevertheless, some modifications of the standard DSSC architecture are mandatory: first and foremost the flexibilization of the electrodes and the optimization of the...
The transparent electrode based on silver nanowire (AgNW) networks has emerged as an outstanding alternative of the electrode based on indium tin oxide (ITO) film in particular for flexible electronics. The polymeric films are popularly applied as flexible substrates and thus the electrode employing AgNWs and polymeric film is potential to be widely used in our daily life. However, the applications...
We have investigated the stability of key electro-optical properties (Conductivity, Work Function, Transmittance) of several commonly used electrode materials for organic optoelectronics (Indium-Tin Oxide, Gold, Silver, Aluminum) in different media (Air, DI water, Phosphate Buffered Saline and Dulbecco's Modified Eagle Medium). By comparing the electrode materials side by side, we aimed to identify...
We have investigated the stability of the electrical performances in staggered organic thin film transistors (OTFTs) manufactured by using a CYTOP fluoropolymer as a gate dielectric, after the devices underwent reliability cycles in a high moisture and temperature controlled environment chamber. The results of such testing cycles showed a very high stability against the environmental conditions that...
