Extended Data Fig. 4: Self-restoring nanocrystalline sowing.
From: Flexible silicon solar cells with high power-to-weight ratios
a, Relationship between the FF and crystallinity fraction of the n+:nc-SiOx:H window layer with a p+:a-Si:H rear emitter. b, Relationship between the FF and crystallinity fraction of the p+:nc-Si:H rear emitter with the optimal n+:nc-SiOx:H window layer. c,d, Variation of CH in i:a-Si:H (2) with sowing duration via self-restoring nanocrystalline sowing and unrestricted nanocrystalline sowing, respectively. e, Enlarged cross-sectional HRTEM image of i:a-Si:H (2) after the unrestricted nanocrystalline sowing. The dashed lines in the panels (a, b, c, d) are fit lines to evaluate the data change trends.
