Special Issue Information

Dear Colleagues,

Solar power or photovoltaics has been globally considered for promoting renewable energy to realize energy sustainability. However, solar power is intermittent in nature, thus requiring energy storage to be coupled with it.

On the other side, forms of energy storage such as batteries are energy-limited, making their recharge a requirement. Solar power can help to accomplish this recharging requirement. This makes the two systems (solar and energy storage) mutually dependent in nature.

However, the mass adoption of solar power/energy storage systems has been restrained by its high cost, especially for residential photovoltaics. This creates the need for a low-cost and efficient combination of solar and energy storage, new energy conversion technologies (solar, batteries, supercapacitors), and operation optimization of solar power storage at the system level.

For this Special Issue, we encourage the submission of relevant papers (communications, full research articles, review articles) on designs that implement solar energy storage focusing on device (materials, processes, device architectures and structures) and system level (microgrids), aiming at better performance and a lower cost.

We encourage the submission of papers exploring material, device, and system levels. Potential topics include but are not limited to:

  • Solar/battery combination or architecture;
  • Solar/supercapacitor combination or architecture;
  • High-efficiency solar cells (silicon, thin films, perovskites, organic);
  • High-energy and -power-density energy storage (batteries: lithium-ion, solid-state, beyond Li-ion; supercapacitors: EDLC, pseudo, hybrid; Li-ion capacitors);
  • Solar storage and battery charging algorithms for performance optimization;
  • System-level design, operation, and control of solar-storage for microgrid optimization.

Profilometry is useful in detecting surface faults on solar concentrators, which can be imperfectly manufactured, thus affecting system performance. Profilometric analyses are performed on a micro-parabolic trough collector (m-PTC), with reduced sizes and greater mirror curvature than a usual PTC. The peculiar dimensions and shape of this micro-PTC request to develop a specific configuration of laser profilometry. It includes a laser diode with a converging lens placed in front of it, ensuring that the mirror curvature does not affect the beam reflection. A new method to calculate the spot position furnishes the reflected beam center even if it lies outside the target, giving it a virtual expansion. The profile is assessed with an iterative calculation, starting from a first point, physically measured. The results are the 3D profile reconstruction of the parabolic mirror and a map of the slope error for each mirror point. It also estimates the intercept factor, a parameter fundamental to optimize the m-PTC system, whose value is in agreement with a structured light measurement on the same object. This intercept factor was obtained averaging the local intercept factor calculated for each mirror point, which individuates the mirror portions not focusing the sunrays on the tube. Full article
