Progress and Perspectives of Thin Film Kesterite Photovoltaic Technology: A Critical Review
Sergio Giraldo,Zacharie Jehl,Marcel Placidi,Victor Izquierdo-Roca,Alejandro Pérez-Rodríguez,Alejandro Pérez-Rodríguez,Edgardo Saucedo +6 more
TL;DR: Kesterite is currently the most promising emerging fully inorganic thin film photovoltaic technology based on critical raw-material-free and sustainable solutions and doping and alloying strategies are proposed as critical for enhancing the conversion efficiency of kesterite.
Journal ArticleDOI
In-depth resolved Raman scattering analysis for the identification of secondary phases: Characterization of Cu2ZnSnS4 layers for solar cell applications
X. Fontané,Lorenzo Calvo-Barrio,Victor Izquierdo-Roca,Edgardo Saucedo,Alejandro Pérez-Rodríguez,Joan Ramon Morante,Dominik M. Berg,Phillip J. Dale,Susanne Siebentritt +8 more
TL;DR: In this article, the in-depth resolved Raman scattering analysis with different excitation wavelengths of Cu2ZnSnS4 layers is presented, showing peaks that are not detectable by excitation in the visible.
Journal ArticleDOI
Multiwavelength excitation Raman scattering study of polycrystalline kesterite Cu2ZnSnS4 thin films
Mirjana Dimitrievska,Andrew Fairbrother,Xavier Fontané,Tariq Jawhari,Victor Izquierdo-Roca,Edgardo Saucedo,Alejandro Pérez-Rodríguez +6 more
TL;DR: In this article, a complete analysis of all Raman active modes of Cu2ZnSnS4 measuring with six different excitation wavelengths from near infrared to ultraviolet was presented.
Journal ArticleDOI
Influence of average size and interface passivation on the spectral emission of Si nanocrystals embedded in SiO2
B. Garrido Fernandez,María M. López,C. García,Alejandro Pérez-Rodríguez,Joan Ramon Morante,Caroline Bonafos,M. Carrada,Alain Claverie +7 more
TL;DR: In this article, a method for imaging Si nanocrystals in SiO2 matrices was proposed by using high-resolution electron microscopy in conjunction with conventional electron microscope in dark field conditions.
Journal ArticleDOI
Development of a selective chemical etch to improve the conversion efficiency of Zn-rich Cu2ZnSnS4 solar cells.
Andrew Fairbrother,E. García-Hemme,Victor Izquierdo-Roca,Xavier Fontané,F.A. Pulgarín-Agudelo,Osvaldo Vigil-Galán,Alejandro Pérez-Rodríguez,Alejandro Pérez-Rodríguez,Edgardo Saucedo +8 more
TL;DR: A selective chemical etching process based on the use of hydrochloric acid solutions to remove Zn-rich secondary phases from the CZTS film surface, which are partly responsible for the deterioration of the series resistance of the cells and, as a consequence, the conversion efficiency.
