The Ni/NiOx films were deposited onto micro-glass substrates by spray pyrolysis (SPD). As precursors, aqua nickel acetate solutions were used. Deposition parameters such as temperature substrate and spraying solution concentration were varied for optimizing the Ni/NiOx cermet properties. The optical properties of the films (a, e) were correlated with their chemical composition, crystalline structure and morphology. At the deposition condition, the major phase is cubic NiO. The annealing increases the crystallinity degree offering good values of solar absorbance (a=0.91) and emittance (e=0.07).

ABSTRACTWe present rational computational design of phenothiazine dyes for dye-sensitized solar cells containing different five-membered rings (thiophene, furan, and selenophene) by a combined strategy of modified conjugation order and functionalization leading to the quinoidization of the ring. We predict that it is possible to lower the excitation energy by 20% vs. the parent dye by the combination of: change in the conjugation order of the methine unit, its functionalization by the CN group, and replacement of the thiophene ring by furan.

In this work, we aim to reduce the production costs of Perovskite solar cells (PSCs) and achieve high solar absorbance with the inclusion of different shapes of plasmonic nanoparticles within its 200 nm thick Perovskite layer. We have performed an extensive study based on the different morphologies of plasmonic nanoparticles including nanospheres, nanocubes, nanocylinders, nanorods, nanotriangular plates embedded within the film. This geometric study is extended to the different orientations of a particle within the film, with respect to the source of light. Based on our previous study involving different materials of nanoparticles within the perovskite film, copper is selected as a potential candidate to drastically reduce the production costs without compromising the absorption efficiency of the cell. Varying sizes of these copper nanoparticles are placed at the centre of the film to verify the enhancement of the light trapping efficiency of these designed cells. We find that the absorption efficiency of PSCs highly depends upon the corner sharpness and orientation of a nanoparticle within the film, though the average absorption remains analogous to the spherical particles. Since the designed PSC with tailored nanoparticles portray a significant variation in its absorbance efficiency with the change in its geometrical parameters, hence we can choose a specific morphology of the particle, placed at a certain angle within the film to obtain maximum absorbance. The entire study is based on the Finite Difference Time Domain (FDTD) method of simulation. Keywords Perovskite solar cells, solar absorbance, plasmonic Nanoparticles, FDTD
