In this paper, we report energy conversion efficiencies of 20.8% from CZ and 22.7% from FZ n-type silicon substrates, by a rear emitter PERT (passivated emitter, rear totally-diffused) cell structure. Record efficiency of 22.7% and excellent open-circuit voltage of 706 mV have been demonstrated by these rear emitter cells on n-type FZ substrates. The comparable high efficiency from the CZ substrates...
The dark I-V characteristics of crystalline silicon solar cells usually deviate from that expected by classical diode theory by an unusually high ideality factor and magnitude at biases smaller than about 0.5 V. It had been shown that the recombination current is flowing preferentially in certain local extended defect positions like the edge or local shunts. There, the local density of recombination...
PERT (passivated emitter, rear totally-diffused) cells on CZ and FZ n-type silicon substrates have demonstrated high efficiencies of 21.1% and 21.9%, respectively. Performance loss has been observed in these cells after over two-year storage. A further loss was observed when these cells were illuminated under one-sun intensity using ELH halogen projection lamps. The lightly doped boron emitters and...
