The High-Low Emitter (HLE) Si Solar Cell

The lighted current-voltage characteristic and spectral response for the highlow emitter solar cell in low level injection are derived. Numerical calculations and analyses are performed. Numerical calculations and analyses are performed. The results show that the HLE cell which has a shallow heavily doped region and a deeper low doped region has better spectral responses than that of conventional cell,so HLE structure can be used for improving the spectral response and increasing the short circuit current of the cell. Another advantage of the HLE cell is the suppression characteristics for dark emitter current. Therefore the large value of open circuit voltage can be obtained for this cell.
