Carrier recombination losses in inverted polymer: Fullerene solar cells with ZnO hole-blocking layer from transient photovoltage and impedance spectroscopy techniques.
Garcia-Belmonte, Germà; Pérez Boix, Pablo; Ajuria, Jon; Palacios, Roberto © 2011 American Institute of Physics (2011-04)In this study, full coincidence between impedance spectroscopy and transient photovoltage techniques in measuring recombination kinetics of photogenerated charge carriers in inverted polymer:fullerene organic solar cells ... -
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 ... -
Kinetics of occupancy of defect states in poly(3-hexylthiophene): fullerene solar cells
Garcia-Belmonte, Germà; Boix, Pablo P; Ajuria, Jon; Etxebarria, Ikerne; Palacios, Roberto Elsevier (2012-01)Energetics and kinetics of defects in the effective band gap of organic bulk heterojunctions are determined by means of capacitance methods. The technique consists of calculating the junction capacitance derivative with ... -
Role of Zn0 electron-selective layers in regular and inverted bulk heterojunction solar cells
Garcia-Belmonte, Germà; Bisquert, Juan; Pérez Boix, Juan; Pacios, Roberto; Etxebarria, Ikerne; Ajuria, Jon American Chemical Society (2011-02)Here the role of metal oxide (ZnO) electron-selective layers in the operating mechanisms of bulk-heterojunction polymer−fullerene solar cells is addressed. Inverted as well as regular structures containing ZnO layers at ...
