We report on our attempt to improve the performance of passivated emitter and rear cell (PERC) performance by introducing a selective emitter technology using a screen-printed resist masking combined with wet chemical etch-back process. Applying selective emitter concept is aimed to decrease the recombination losses at the front surface of the cell.
