Research on automatic tracking solar concentrator photovoltaic systems has gained increasing focus in developing the solar PV technology. A paraboloidal concentrator with secondary optic is developed for a three-junction GaInP/GalnAs/Ge solar cell. The concentration ratio of this system is 200 and the photovoltaic cell is cooled by heat pipe. A detailed analysis on the temperature coefficient i...

We report the photoelectrochemical (PEC) oxidation of methanol on a rationally designed graphene-TiO2 nanorod array (G-TNR) photoanode. A PEC methanol fuel cell was constructed by coupling the G-TNR photoanode with a cathode. This study raises a conceptual fuel cell that realizes the synergistic energy conversion of chemical energy and solar energy.

We describe high efficiency thin-film InP solar cells that utilize a periodic array of TiO2 nanocylinders. These nanophotonic resonators are found to reduce the solar-weighted average reflectivity of an InP solar cell to ~1.3%, outperforming the best double-layer antireflection coatings. The coupling between Mie scattering resonances and thin-film interference effects accurately desc...

today, due to qualitative growth and scientific advances, energy, especially electricity is increasingly needed by human society. one of the almost endless and pure energy which have been paid attention over the years is the solar energy. solar cells directly convert solar energy into electrical energy and are one of the main blocks of photovoltaic systems. significant improvement has been made...

This paper presents a method of modeling and simulation of photovoltaic arrays in MATLAB® /Simulink® using solar cell block from SimElectronics® library. The method is used to determine the characteristic of a particular photovoltaic cell panel and to study the influence of different values of solar radiation at different temperatures concerning performance of photovoltaic cells. This model it ...

The objective of this project is to create clean fuel for transportation using hydrogen powered by solar energy. Hydrogen has been generated by solar photovoltaic (PV) array and then collected for data analysis to demonstrate efficiency of the hydrogen production in all the steps of the experiment. The hydrogen produced from the electrolysis process was either stored in a metal hydride canister...

Self-sustainable energy sources are essential for a wide array of wireless applications deployed in remote field locations. Due to their self-assembling and self-repairing properties, "biological solar (bio-solar) cells" are recently gaining attention for those applications. The bio-solar cell can continuously generate electricity from microbial photosynthetic and respiratory activities under d...
