Design of experiments optimization of fluorine-doped tin oxide films prepared b...
Pinheiro, X.L.; Vilanova, A.; Mesquita, D.; Monteiro, M.; Eriksson, J.A.M.; Barbosa, J.R.S.; Matos, C.; Oliveira, A.J.N.; Oliveira, K.; Capitão, J.Transparent conducting oxides (TCOs) have witnessed an ever-expanding use in our lives through many optoelectronic applications, namely photovoltaic (PV) devices. Indium-tin oxide (ITO) is the most used and studied TCO, but it lacks thermal and chemical stability and indium is a scarce and toxic element. Fluorine-doped tin oxide (FTO) emerged as the most promising alternative to ITO, presenting better thermal a...
Solar water splitting under natural concentrated sunlight using a 200 cm(2) pho...
Vilanova, A.; Dias, P.; azevedo, j.; Wullenkord, M.; Spenke, C.; Lopes, T.; Adélio MendesThis work reports a 200 cm(2) PEC-PV device that comprises four 50 cm(2) PEC cells coupled in a modular array and optimized for continuous operation under concentrated sunlight. The developed module is the second largest PEC-PV device ever reported and the first tested under natural concentrated sunlight (up to 12.8 kW m(-2)). Demonstration tests were conducted outdoor in a continuous operation mode, over four ...
Optimized photoelectrochemical tandem cell for solar water splitting
Vilanova, A.; Lopes, T.; Carsten Spenke; Michael Wullenkord; Adélio MendesIn the field of photoelectrochemical (PEC) hydrogen production most studies focus on developing efficient nanostructured materials and less attention is given to the optimization of PEC devices. However, the reactor design greatly influences the overall performance of these devices and it is a key element to turn PEC hydrogen generation competitive and marketable. In this work, a 50 cm(2) tandem PEC-PV cell, na...
