Sr. Dhariwal et Rc. Sharma, FIELD-ASSISTED RECOMBINATION IN SILICON SOLAR-CELLS WITH HEAVILY DOPED BASE - A LOSS MECHANISM FOR THE OPEN-CIRCUIT VOLTAGE, Semiconductor science and technology, 7(3), 1992, pp. 315-319
An explanation for much lower open-circuit voltages of silicon pn junc
tion solar cells with heavily doped base layers has been obtained. Eff
ects due to bandgap narrowing, lifetime and minority carrier mobility
variations do not fully explain such a reduction. Field-assisted recom
bination is identified as an important mechanisms for the loss of open
-circuit voltages in these solar cells.
