Transition metal oxides (TMOs) are promising materials to develop selective contacts on high-efficiency crystalline silicon solar cells. Nevertheless, the standard deposition technique used for TMOs is thermal evaporation, ...

This paper presents the design and construction of Guanay II vehicle. It is an autonomous underwater vehicle that navigates over the sea surface and, at certain fixed points, dives vertically to obtain a profile of a water ...

This work proposes the development of a control system for an autonomous underwater vehicle dedicated to the observation of the oceans. The vehicle, a hybrid between Autonomous Underwater Vehicles (AUVs) and Autonomous Surface ...

This work studies the use of polymeric layers of polyethylenimine (PEI) as an interface modification of electron-selective contacts. A clearly enhanced electrical transport with lower contact resistance and significant ...

This work studies a novel electron-selective contact for n-type silicon solar cells based on the modification of the cathode with a polymeric interlayer. Specifically, a thin layer of the conjugated polyelectrolyte PFN is ...

The interdigitated back-contacted (IBC) solar cell concept has been extensively studied for single-junction cells and more recently as a good choice for three-terminal tandem devices. In this work, carrier-selective contacts ...

Aquest treball de màster mostra com es pot utilitzar la nanotecnologia com a fil conductor que permeti, per una banda, millorar les competències STEM de l'alumnat de l'ensenyament secundari obligatori. I per altra banda, ...
