Overview over simulated cells with same IQE at 600 nm as best IBC cells on high and low doping absorbers.
| Simulated case | High doping (IQE(600 nm) = 72.9%) | Low doping (IQE (600 nm) = 81.2%) | ||||||
|---|---|---|---|---|---|---|---|---|
| S front (cm/s) | τbulk (μs) | L diff (μm) | V OC (mV) | S front (cm/s) | τbulk (μs) | L diff (μm) | V OC (mV) | |
| Bulk limited | 0 | 0.6 | 18.2 | 652 | 0 | 1.0 | 25.2 | 617 |
| Medium | 500 | 1.4 | 22.4 | 655 | 500 | 2.5 | 28.4 | 623 |
| Interface limited | 1400 | 150 | 22.6 | 662 | 800 | 150 | 31.9 | 630 |
Three cases were simulated: bulk limited, interface limited, and one intermediate case. S front, τbulk input parameters are listed with their respective resulting L diff.
