How much gallium do we need for a p-type Cu(In,Ga)Se2?
Omar Ramírez, Evandro Martin Lanzoni, Ricardo G. Poeira +4
Doping in the chalcopyrite Cu(In,Ga)Se2 is determined by intrinsic point defects. In the ternary CuInSe2, both N-type and P-type conductivity can be obtained depending on the growt…
Electrical barriers and their elimination by tuning (Zn,Mg)O composition in Cu(In,Ga)S2: Systematic approach to achieve over 14% power conversion efficiency
Mohit Sood, Poorani Gnanasambandan, Damilola Adeleye +4
Traditional CdS buffer layer in selenium-free Cu(In,Ga)S2 solar cells leads to reduced open-circuit voltage because of a negative conduction band offset at the Cu(In,Ga)S2/CdS inte…
Broadband wavelength-selective isotype heterojunction n+-ZnO/n-Si photodetector with variable polarity
Georgios Chatzigiannakis, Angelina Jaros, Renaud Leturcq +4
An isotype heterojunction n+-ZnO/n-Si photodetector is developed, demonstrating wavelength-selective or broadband operation, depending on the applied bias voltage. Additionally, at…
Laser-microstructured ZnO/p-Si photodetector with enhanced and broadband responsivity across the UV-Vis-NIR
Georgios Chatzigiannakis, Angelina Jaros, Renaud Leturcq +4
We develop ZnO/p-Si photodetectors by atomic layer deposition (ALD) of ZnO thin films on laser-microstructured silicon and we investigate their electrical and optical behavior, dem…
Detection mechanism in highly sensitive ZnO nanowires network gas sensors
Nohora Caicedo, Renaud Leturcq, Jean-Pierre Raskin +2
Metal-oxide nanowires are showing a great interest in the domain of gas sensing due to their large response even at a low temperature, enabling low-power gas sensors. However their…
A high aspect ratio Fin-Ion Sensitive Field Effect Transistor: compromises towards better electrochemical bio-sensing
Serena Rollo, Dipti Rani, Renaud Leturcq +2
The development of next generation medicines demand more sensitive and reliable label free sensing able to cope with increasing needs of multiplexing and shorter times to results.…
