Bromine etching of kesterite thin films: perspectives in depth defect profiling and device performance improvement
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Text en actes de congrés
Accés restringit per política de l'editorialUsing a controlled bromine etching on kesterite absorbers, two major results are obtained. We establish the first defect depth profiling and secondary phases depth profiling of a state of the art Cu2ZnSnSe4 (CZTSe) film ... -
Study of PV systems for self-consumption at the UPC based on simulations by using PVSol
(Czech Technical University, 2022)
Comunicació de congrés
Accés obertThe aim of this work is to carry out a sustainability study in five campuses of the Universitat Politècnica de Catalunya BarcelonaTech (UPC) around Catalunya, i.e. Campus North and South Campuses in Barcelona city, Campus ... -
Laser fired contacts on amorphous silicon deposited by hot-wire cvd on crystalline silicon
(WIP Wirtschaft und Infrastruktur GmbH & Co. Planungs-KG, 2008)
Text en actes de congrés
Accés restringit per política de l'editorialIn this work we study aluminium laser-fired contacts for intrinsic amorphous silicon layers deposited by Hot-Wire CVD. This structure could be used as an alternative low temperature back contact for rear passivated ... -
The origin of emitter-like recombination for inverted c-Si surfaces
(WIP Wirtschaft und Infrastruktur GmbH & Co. Planungs-KG, 2008)
Text en actes de congrés
Accés restringit per política de l'editorialc-Si samples whose surface passivation is based on highly inverted surfaces experimentally show a decrease in effective lifetime at low illumination levels while a flat dependence is expected from the current theoretical ... -
Understanding noise-shaping in sigma-delta controls of surface potential for MOX gas sensors
(Institute of Electronics, Information and Communications Engineers (IEICE), 2018)
Text en actes de congrés
Accés restringit per política de l'editorialThe objective of this paper is to explain how quantization noise-shaping can be achieved for the output bitstream of sigma-delta controls of surface potential (SP) in MOX gas sensors. These controllers use temperature ... -
Exploring the performance of a miniature 3D wind sensor under extreme martian winds up to the dust devil scale
(2019)
Text en actes de congrés
Accés obertThe objective of this paper is to explore the performance of a miniature 3D spherical wind sensor for Mars atmosphere, working under extreme wind speeds, up to the Dust Devil scale. The experimental campaign has been made ... -
Testing campaign of a martian spherical wind sensor at the AWTSII Wind Tunnel Facility
(2018)

Origin of the negative differential resistance in the output characteristics of a picene-based thin-film transistor
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Text en actes de congrés
Accés obertIn this work, we have fabricated and studied p-type picene thin-film transistors. Although the devices exhibited good electrical performance with high field-effect mobility (up to 1.3 cm2/V¿s) and on/off ratios above ... -
Electron selective contacts based on Al2O3/TiO2/ZnO stacks for crystalline silicon solar cells
(2018)
Comunicació de congrés
Accés restringit per política de l'editorialIn the last years, our research group has focused on the development of Interdigitated Back Contacted (IBC) solar cells based on transition metal oxides. In particular, a very thin Al2O3/TiO2 stack deposited by ALD has ...
