Development of nanodoped conducting polymers for solar cells.
Different organic semiconducting polymer, such as poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS); poly(3-hexylthiophene) (P3HT) or, more recently, Poly(triarylamine) (PTAA) exhibit high transparency and relatively high hole mobility, making it an attractive hole-transport material in optoelectronic applications such as organic light emitting diodes and perovskite photovoltaic devices. Notably, PTAA was used as the hole transport layer in the world-record, 22.1% efficiency perovskite solar cell. Its principal advantages compared to other traditional semiconducting polymers are its stability in air, resistance to degradation by exposure to UV light or moisture, and ability to be annealed at low temperatures, making it amenable to high-throughput roll-to-roll processing.
Multifunctional coatings for higher efficiency of the wind blades
This proposal consists on the manufacture of multifunctional coatings, based on polymer doped with nanofillers, in order to develop ADIS system (Anti-icing and de-icing systems). The system is based on the self-heating due to Joule´s effect of the electrical conductor coating reinforced with graphitic nanofillers. This project could solve this problem using the same installed wind blades, applying a maintenance operation consisted on the application of a new coating
