The pursuit of high-power solar laser systems with high efficiency and capacity for large tracking error compensation is determinant for the applicability of this renewable technology. A side-pumped dual-rod Ce:Nd:YAG solar laser was developed and tested at the focus of a 2 m diameter parabolic concentrator. Maximum continuous-wave total solar laser power of 58 W was measured. To the best of our knowledge, this is the highest laser power from a Ce:NdYAG solar laser. Moreover, wide tracking error compensation width of 5.1° in the azimuthal direction was reached, being 4.25 times higher than the previous measurement without solar tracking assistance.

Nanoparticles in their pure colloidal form synthesized by laser-assisted processes such as laser ablation/fragmentation/irradiation/melting in liquids have attained much interest from the scientific community because of their specialties like facile synthesis, ultra-high purity, biocompatibility, colloidal stability in addition to other benefits like tunable size and morphology, crystalline phases, new compounds and alloys, and defect engineering. These nanocolloids are useful for fabricating different devices mainly with applications in optoelectronics, catalysis, sensors, photodetectors, surface-enhanced Raman spectroscopy (SERS) substrates, and solar cells. In this review article, we describe different methods of nanocolloidal synthesis using laser-assisted processes and corresponding thin film fabrication methods, particularly those utilized for device fabrication and characterization.

Monolithic perovskite/silicon tandem (PST) solar cells are rapidly emerging as next-generation solar cells with significant potential for commercialization. This study presents a proof of concept for a silicon diffused junction-based PST cell, utilizing a passivated emitter rear contact (PERC) cell with a low-temperature (<200 °C) laser-fired contact process to minimize thermal damage. By introducing amorphous silicon to the emitter surface of PERC bottom cell, the open circuit voltage (V) improve from 0.

Inspired by the electron-withdrawing ability of nitroxide radicals, a novel open-shell material, EDOT-TPAO is reported, synthesized via one-step demethylation and oxidation of its closed-shell precursor, EDOT-TPAOMe. Time-dependent density functional theory calculations confirm an acceptor-donor-acceptor configuration of EDOT-TPAO where radical termini act as electron acceptors. This structural transformation narrows the optical bandgap from 2.
