Solar-energy conversion usually takes one of two forms: the 'quantum' approach, which uses the large per-photon energy of solar radiation to excite electrons, as in photovoltaic cells, or the 'thermal' approach, which uses concentrated sunlight as a thermal-energy source to indirectly produce electricity using a heat engine. Here we present a new concept for solar electricity generation, photon...
Plasmonics can enhance solar energy conversion in semiconductors by light trapping, hot electron transfer, and plasmon-induced resonance energy transfer (PIRET). The multifaceted response of the plasmon and multiple interaction pathways with the semiconductor makes optimization challenging, hindering design of efficient plasmonic architectures. Therefore, in this paper we use a density matrix m...

—This paper presents the solar energy e-learning laboratory, developed at the Higher Technical Institute (HTI) within the framework of the Leonardo da Vinci project MARVEL, focuses on the system architecture and its features, and elaborates on the learning platform employed. The laboratory focuses on experiential based learning-arrangements allowing remote and distributed training with the labo...
Dye-sensitized solar cell (DSSC) is a potential candidate to replace conventional silicon-based solar cells because of high efficiency, cheap cost, and lower energy consumption in comparison with silicon chip manufacture. In this report, mixed-phase (anatase and rutile nanoparticles) TiO2 photoanode was synthesized to investigate material characteristics, carriers transport, and photovoltaic pe...
Over the last few decades, there has been increasing interest in the design and construction of integrated energy conversion and storage systems (IECSSs) that can simultaneously capture and store various forms of energies from nature. A large number of IECSSs have been developed with different combination of energy conversion technologies such as solar cells, mechanical generators and thermoele...
In this research paper an energy system composed of three energy conversion devices namely, photovoltaic panels, a wind turbine, and a battery is proposed. This controller directs power to a fixed voltage DC bus. The fixed voltage bus supplies the load, while the excess power is directed to the batteries. Simulation and control of a hybrid PVwind generator system connected to the load are prese...
