Table 1. Electrical and Photoelectric Parameters of the Three Different Solar Cells Studied in This Articlea.
device | Js (A/cm2) | n | Rs (Ω cm2) | Jsc (mA/cm2) | Voc (V) | FF (%) | PVE (%) |
---|---|---|---|---|---|---|---|
solar cell 1: reference cell, no SiNWs | 1.16 × 10–4 | 1.43 | 1.3 | 22.7 | 0.556 | 72.7 | 9.2 |
solar cell 2 (SiNW cell with grid on SiNWs) | 1.62 × 10–4 | 1.56 | 2.0 | 27.9 | 0.553 | 65.2 | 10.1 |
solar cell 3 (SiNW cell with grid on bulk) | 1.61 × 10–4 | 1.67 | 1.5 | 32.5 | 0.587 | 70.3 | 13.4 |
The SiNW length for solar cells 2 and 3 was 1 μm.
