“…Hence, if the intensity of the incident light is increased a linear response in energy production will be observed: this is the principle on which geometric solar concentrators are based [2]. However, this technology has some disadvantages such as a low efficiency in diffused light conditions and the need of a good system of dispersion of excess heat due to unconverted energy [3].…”

New luminophores having different aryl nuclei and propynones moieties have been obtained via Sonogashira reactions. Their optical properties were evaluated and indicated that carbonyl groups are responsible for significant bathochromic effects and high Stokes shifts. The insertion of-OMe groups on the central benzene unit gives to the fluorophore high optical efficiency (7.7%) when homogeneously dispersed in a poly(cyclohexyl methacrylate) (PCMA) film and connected to a PV cell.

“…In this sense, the peak of efficiency of standard MJ solar cells seems to be limited to concentrations factors below 1000 suns, no matter how the front‐grid pattern is designed or how much the area of the cell is reduced 4,20 . Hence, they cannot fully exploit the theoretical increase of η with C ratio and therefore to completely leverage the cost reduction capacity of UHCPV systems 21 …”

The efficiency of solar cells can be enhanced by increasing the light intensity and/or the number of bandgaps of the structure. However, current solar cells cannot fully exploit these two factors because of various critical drawbacks. Here, we show a novel microscale, that is, side ≈ 0.5 mm, vertical solar cell structure that does not suffer the series resistance and bandgap limitations issues of current devices. The preliminary structures investigated show extreme efficiencies, >40%, at ultrahigh concentration factors of 15 000 suns. In addition, future designs with a better bandgap configuration are expected to deliver cells with efficiencies far above 50% at extreme light intensities. This early design offers a fast and reliable route to push the efficiency towards the maximum solar conversion limit and represents a promising way to develop new‐generation ultraefficient and low‐cost concentrator photovoltaic systems.

“…This heat is transferred inside the PV cell through conduction and is defined as a heat source on the top surface of the PV cell. The dissipation of this heat from the boundary is modeled by convection and is solved using equation (15). Various thermophysical properties of the domains involved in the simulation are provided in Table 2.…”

“…CPV systems not only reduce the space occupied by PV elements but also aim to achieve higher performance by substituting expensive materials with cheaper alternatives, thereby reducing the total cost of the element [14]. Therefore, the receiving part of LWPT system specifically with beam collector or lens is worthy of research and still requires improvement [15]. The geometry of the beam collector needs to be rearranged to collect more beams from the source and minimize nonuniform irradiation.…”

The global energy landscape faces significant challenges in meeting the demands of modern industries for stable and efficient energy supply. Laser wireless power transmission (LWPT) systems, which utilize the photovoltaic effect to convert laser beam energy, hold great promise due to their long-range transmission capability and high precision. However, the current energy conversion efficiency of these systems requires further improvement to achieve optimal performance. To enhance concentrated photovoltaic (CPV) system performance, the study examines different nonimaging concentrators such as reverse truncated pyramid, cross-compound parabolic concentrator, and square elliptical hyperboloid. Numerical simulations using the finite element method analyze the multifield coupling mechanism of PV modules with various concentration lenses. Three CPV systems with RTP concentrators of different heights were studied to understand the impact of geometry on CPV performance. And the main impact of rotation angle was discussed. The research findings provide essential insights into CPV system performance and the influence of different concentration lenses, contributing valuable knowledge towards improving LWPT technologies.
