| Abstract: | Thin layers of lithium fluoride (LiF), together with aluminum, can be used as rear electrodes in high-efficiency amorphous silicon (a-Si:H) solar cells on rough substrates, as recently demonstrated by Fang et al. We employ numerical modeling to evaluate the optical losses and charge generation profiles in these thin film solar cells. We find that the increase in rear electrode reflectivity by inserting LiF, leading to increased photocurrent, is the dominant factor in device performance improvement, accounting for 7% gain in photocurrent. The simulations are in good agreement with measurements of pin a-Si:H solar cells with varied rear electrodes. |
