III-V nanowires (NWs) have recently emerged as a promising candidate for the direct growth of perfect III-V crystals on silicon, and open new perspectives for the conception and fabrication of tandem solar cells. The results published in several articles this … Continued
Congratulations to Romaric de Lépinau, who was rewarded with the best oral presentation during the 2019 edition of the C2N doctoral days that held last week!
Welcome to our new post doc Joya Zeitouny! After a PhD thesis in the PROMES lab in France working on multijunction solar cells and CPV applications, Joya is joining the team to work on ultrathin CIGS solar cells.
Save the date! After the great success of the first PV School on Physics of Solar Cells: from basics to nanoscience in Les Houches from 25-30 March 2018, we are proud to announce the second edition of the PV School … Continued
A new postdoc position is now available on Ultrathin III-V/Si tandem solar cells (download the offer for more information). Other postdoc positions may be offered in 2018 in our team on photovoltaics (ultrathin CIGS, new concepts,…). Don’t hesitate to apply … Continued
The organization of the thematic school on Physics of Solar Cells: from basics to nanoscience is on the road. It will be held in a lovely place called Les Houches (Alps), France, from 25-30 March 2018. Applications must be received … Continued
We present an effective method of determining the doping level in n-type III–V semiconductors at the nanoscale. Low-temperature and room-temperature cathodoluminescence (CL) measurements are carried out on single Si-doped GaAs nanowires. The spectral shift to higher energy (Burstein–Moss shift) and … Continued
Novel architectures for light trapping in ultrathin Cu(In,Ga)Se_2 (CIGS) solar cells are proposed and numerically investigated. They are composed of a flat CIGS layer with nanostructured back mirrors made of highly reflective metals. Multi-resonant absorption is obtained for two different … Continued
Ultrathin c-Si solar cells have the potential to drastically reduce costs by saving raw material, while maintaining good efficiencies thanks to the excellent quality of monocrystalline silicon. However, efficient light trapping strategies must be implemented to achieve high short-circuit currents. … Continued
