The chapter has to contribute to the part of electronic devices related to solar cells development, aided by new innovation technologies and new photovoltaic (PV) cells made by organic compounds and nanomaterials. Also, advances on the part of control techniques by presenting the results for Extremum Seeking Control (ESC)-based Global Maximum Power Point Tracking (GMPPT) applied to PV microgrids in partially shaded regimes are considered. The influence of the photovoltaic arrays topologies to multimodal characteristic of the PV power is also highlighted. Alternative new materials like ferrite Nano-Core-Shell (NCS) multilayer can be used to construct Thin Film Transistors (TFT) or can be applied for photovoltaic (PV) cells. Hence, the chapter firstly presents how the NCS technology generates nanomaterial layers. The ferrite core is self-assembled by an intermediary first shell to an organic shell represented by para-aminobenzoic acid (PABA). The fabricated nano-layers are investigated by Scanning Electron Microscopy technique (SEM) and also by Dynamic Lighting Scattering (DLS). These techniques find a hydrodynamic width for the ferrite NCS of 70.9 nm, besides to a zeta potential for these nanoparticles of 51.6 mV, proving an appropriate stability of the fabricated nanoparticles. Organic semiconductors are recently introduced for the transistor and Organic Solar Cell (OSC) manufacturing. Some Athena/Atlas simulations capture the better feature for the static characteristics for different electronic structures working as transistor or texturized solar cells. Either Nano-Core-Shell, Amorphous-Silicon or Polymers are suitable materials for PV microgrids. The demonstration of current vectors traces and experimental static characteristics of the proposed electronic devices sustain these materials future use to enhance the PV arrays. Furthermore, the energy generated by the PV arrays can be fully harvested using GMPPT algorithm based on advanced ESC scheme. |
