Measures to increase the opencircuit voltage, the fill factor and short circuit current density are discussed both theoretically and technologically for an efficient silicon solar cell.
The opencircuit voltage of the cell under dynamic operating is higher than that under steady state owe to the reduction of mixed potential caused by methanol crossover.
