Sub-Bandgap Sensitization of Perovskite Semiconductors via Colloidal Quantum Do...
Ribeiro, Guilherme; Ferreira, G.; Menda, U.D.; Alexandre, Miguel; Brites, Maria João; Barreiros, M. Alexandra; Jana, S.; Águas, Hugo; Martins, RodrigoABSTRACT: By taking advantage of the outstanding intrinsic optoelectronic properties of perovskite-based photovoltaic materials, together with the strong near-infrared (NIR) absorption and electronic confinement in PbS quantum dots (QDs), sub-bandgap photocurrent generation is possible, opening the way for solar cell efficiencies surpassing the classical limits. The present study shows an effective methodology ...

Estratégias fotónicas para fotovoltaico : novos avanços para além da ótica
Mendes, Manuel Joao; Sanchez-Sobrado, O.; Haque, S.; Centeno, Pedro; Alexandre, Miguel; Ribeiro, Guilherme; Boane, J.; Mateus, T.; Mouquinho, AnaRESUMO: Estruturas fotónicas com tamanhos comparáveis aos comprimentos de onda da luz solar são as soluções preferenciais para melhorar a eficiência de dispositivos fotovoltaicos através de aprisionamento de luz. As micro-estruturas fotónicas aqui desenvolvidas operam no regime de ótica de ondas, pelo que foram construídos modelos eletromagnéticos que permitiram encontrar os parâmetros ótimos para aplicação no ...
