Scholarcy highlights

  • The impurity photovoltaic effect of the gold donor level in silicon has been observed
  • The spectral response of the open circuit voltage was measured with a lock-in technique
  • Generalization to any deep center was made in view of solar cell performance. it is concluded that no improvement of solar cell efficiency can be acheived by doping with deep traps, because the additional utilization of low energy photons is overcompensated by an enhanced minority carrier recombination
  • Keywords solar cells efficiency impurity absorption silicon. This material was presented in part at the Seventh Photovoltaic Specialists Conference of the Institute of Electrical and Electronic Engineers, Pasadena, Calif.,
