Charged grain boundaries reduce the open circuit voltage of polycrystalline solar cells--An analytical description
Benoit Gaury, Paul M. Haney
Analytic expressions are presented for the dark current-voltage relation of a junction with positively charged columnar grain boundaries with high defect density. The…
Minority-carrier dynamics in semiconductors probed by two-photon microscopy
Benoit Gaury, Paul M. Haney
Two-photon time-resolved photoluminescence has been recently applied to various semiconductor devices to determine carrier lifetime and surface recombination velocities. So far the…
Depletion region surface effects in electron beam induced current measurements
Paul M. Haney, Heayoung P. Yoon, Benoit Gaury +1
Electron beam induced current (EBIC) is a powerful characterization technique which offers the high spatial resolution needed to study polycrystalline solar cells. Current models o…
Probing surface recombination velocities in semiconductors using two-photon microscopy
Benoit Gaury, Paul Haney
The determination of minority-carrier lifetimes and surface recombination velocities is essential for the development of semiconductor technologies such as solar cells. The recent…
