Article
Restricted access - publisher's policyThis work studies the charge carrier collection efficiency in organic bulk-heterojunction solar cells based on polymer:fullerene blends. An equivalent circuit with a specific recombination term is proposed to describe the ... -
Analysis of the electric field changes due to lightning during Catalonia thunderstorms in Summer 2003
(2004)
Conference lecture
Restricted access - author's decisionElectric fields related to lightning close to storms were measured in the Catalonian region (NE of Spain) in summer 2003. The aim of this campaign was the data collection to study the total electrical charge involved in ... -
Balanced tangential testing for the nonconforming discretization of the Electric-Field Integral Equation on open PeC surfaces
(Institute of Electrical and Electronics Engineers (IEEE), 2016)
Conference report
Restricted access - publisher's policyRecent attention has been devoted to the development of nonconforming implementations of the Electric-Field Integral Equation (EFIE), which impose no continuity constraints in the expansion of the current between ... -
Basis for lightning warning systems based in natural electric field measurement
(2003)
Conference lecture
Restricted access - author's decisionThe natural earth electric field is disturbed when a thundercloud is present, the evolution of the electrification before a lightning discharge gives enough time to do actions against possible lightning damages. Different ... -
Charge-induced force noise on free-falling test masses: results from LISA pathfinder
