On the methods of calculation of the charge collection efficiency of dye sensitized solar cells
(Royal Society of Chemistry, 2013)
The charge collection efficiency is one of the most critical parameters of photovoltaic devices. In this paper we provide the analysis and comparison between several approaches for the calculation of the collection efficiency ...
Solution-processed small molecule:fullerene bulk-heterojunction solar cells: impedance spectroscopy deduced bulk and interfacial limits to fill-factors
(Royal Society of Chemistry, 2013)
Using impedance spectroscopy, we demonstrate that the low fill factor (FF) typically observed in small molecule solar cells is due to hindered carrier transport through the active layer and hindered charge transfer through ...
Plasmon-enhanced photocurrent in quasi-solid-state dye-sensitized solar cells by the inclusion of gold/silica core–shell nanoparticles in a TiO2 photoanode
(Royal Society of Chemistry, 2013-09)
Direct evidence of the effects of the localized surface plasmon resonance (LSPR) of gold nanoparticles (Au NPs) in TiO2 photoanodes on the performance enhancement in quasi-solid-state dye-sensitized solar cells (DSCs) is ...
Charge carrier transport and contact selectivity limit the operation of PTB7-based organic solar cells of varying active layer thickness
(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 ...
Temperature effects in dye-sensitized solar cells
(Royal Society of Chemistry, 2013)
In the standard solar cell technologies such as crystalline silicon and cadmium telluride, increments of
temperature in the cell produce large variations in the energy conversion efficiency, which decreases at a
constant ...
Relaxation of Photogenerated Carriers in P3HT:PCBM Organic Blends
(Wiley, 2009)
Relaxing in the sunlight. Long time-transient decays of photogenerated carriers in P3HT:PCBM blends for organic solar cells are interpreted in terms of the relaxation of hole carriers in a broad density of states.
The ...
Recombination in Quantum Dot Sensitized Solar Cells

Quantum dot sensitized solar cells (QDSCs) have attracted significant attention as promising third-generation photovoltaic devices. In the form of quantum dots (QDs), the semiconductor sensitizers have very useful and often ...
Light Capacitances in Silicon and Perovskite Solar Cells
(Elsevier, 2019)
The framework on which the physics of silicon solar cells (SiSCs) is based robustly predicts
dependences of capacitance on light intensity and voltage, even when most recent innovations
are considered as the incorporation ...
Light intensity modulated impedance spectroscopy (LIMIS) in all-solid-state solar cells at open-circuit
