A review of recent results on electrochemical determination of the density of electronic states of nanostructured metal-oxide semiconductors and organic hole conductors
Bisquert, Juan; Fabregat-Santiago, Francisco; Mora-Sero, Ivan; Garcia-Belmonte, Germà; Barea, Eva M; Palomares, Emilio Elsevier (2008)The paper reviews recent results on electrochemical methods applied to the determination of the density of electronic states in several components of advanced nanostructured devices such as the dye solar cell (Grätzel ... -
Charge carrier transport and contact selectivity limit the operation of PTB7-based organic solar cells of varying active layer thickness
Guerrero, Antonio; Montcada, Núria F.; Ajuria, Jon; Etxebarria, Ikerne; Pacios, Roberto; Garcia-Belmonte, Germà; Palomares, Emilio Royal Society of Chemistry (2013-08)In this work we study the different electrical loss pathways occurring during the operation of bulk heterojunction solar cells by using a variety of electrical and optical characterization techniques beyond the current ... -
Inverted vs Standard PTB7:PC70BM Organic Photovoltaic Devices. The benefit of highly selective and extracting contacts in device performance
Etxebarria, Ikerne; Guerrero, Antonio; Albero, Josep; Garcia-Belmonte, Germà; Palomares, Emilio; Pacios, Roberto Elsevier (2014)In this work we compare the photovoltaic performance of different cell designs, standard and inverted, for one of the most promising systems to achieve power conversion efficiencies over 10% in polymer:fullerene single ... -
Tunable Carbon–CsPbI3 Quantum Dots for White LEDs
Rafat Rafiei, Rafat; Gualdrón Reyes, Andrés Fabián; Masi, Sofia; Azizollah Ganji, Bahram; Taghavinia, Nima; Gené Marimon, Santi; Palomares, Emilio; Mora-Sero, Ivan Wiley (2020-12-06)In this work, a simple method to prepare white light emissive diodes based on quantum dot (QD) colloidal solutions using mixed carbon QDs (CQDs) and CsPbI3 perovskite (PQDs) is reported. The right combination generates ...
