“…PV textiles [1,11,[15][16][17][18][19][20][21][22][23][24][25][26][27][28] can be defined as textile materials that can show a PV effect in addition to their functionalities. The PV feature can be given as an integration of a PV module onto the textile structure by sewing or bonding [20,29,30], or the textile structure can be the substrate of the PV structure [1,11,[31][32][33][34][35][36][37].…”

Solar energy is one of the most popular energy sources among the other renewable energies. Photovoltaic technology is a clean way to generate electricity from sunlight. Flexible photovoltaics enable portable electronic devices to power at off-grid conditions. Stainless steel mesh fabric was used as a substrate and electrode allowing the light to reach the photoactive layer. The photoactive layer and hole transport layer were deposited by the means of dip-coating like in the textile industry. The metal back electrode was evaporated in a thermal evaporator under vacuum. Promising results were obtained from photovoltaic measurements. About 0.69% power conversion efficiency was obtained from textile-based solar cells in this study. The textile-based metal fabric enables a flexible photovoltaic structure that can be integrated on non-planar surfaces to generate electricity, and also mesh structure allows the light to reach the photoactive layer.

We report on the successful preparation of Fe-N codoped Titania powders, using TiO 2 Degussa P25, salt of Fe (II), and Urea. Modified Titania-based materials were characterized by SEM, EDS, BET, Raman, XRD diffraction and diffuse reflectance UV-vis spectroscopy measurements. The doping of TiO 2 induced a shift in the absorption threshold towards the spectral range, obtaining catalysts with a greater photoactivity than the one of pure Degussa P25. The degradation of 200 mL of a solution with 50 mgL-1 acid blue BR dye in sulfate medium at pH 3.0 has been comparatively studied by electrochemical oxidation using a boron doped diamond anode (EO-BDD), Photocatalysis TiO 2-Fe-N, and coupled material of EO-BDD/Photocatalysis TiO 2-Fe-N. The solution was slowly degraded by EO-BDD (25%) and single Photocatalysis TiO 2-Fe-N because of the low rate of dye degradation and its colored by-products with hydroxyl radicals generated at the BDD anode and catalyst surface from water oxidation (29%), whereas the solution was more rapidly degraded using coupled material of EO-BDD/Photocatalysis TiO 2-Fe-N (82%), owing to the additional generation of hydroxyl radicals from the photocatalysis of TiO 2-Fe-N and BDD anode.
