Dye-sensitized 1D anatase TiO2 nanorods for tunable efficient photodetection in...
Parreira, P.; Torres, Erica; Nunes, Clarisse; Carvalho, C. Nunes de; Lavareda, G.; Amaral, A.; Brites, Maria JoãoTiO2 films with enhanced photosensitivity were deposited on alkali free glass substrates without intentional substrate heating by pulsed DC magnetron reactive sputtering with an average thickness of about 2 μm. Three dyes, commercial N719 and two new organic dyes were impregnated in order to control the optical spectral selectivity of such films. The type of dye used proved to dramatically influence the device'...
Novel solar absorber surfaces with organic pigments
Nunes, Clarisse; Brites, Maria João; Mendes, J. Farinha; Prates, Manuel João Lopes; Alexandre, J.; Ferreira, M.; Martins, A. J.; Teixeira, V.This paper presents results of application of natural and synthetic organic pigments in selective solar absorber coatings. Some of these photo excite pigments were tested like solar radiation absorber pigments in paint coatings and others as a form to increase the absorption of solar radiation in titanium oxide monolayer selective coatings produced by reactive magnetron sputtering. Morphologic aspects and optic...
