Single junction a-SiOx:H cells with an i-layer thickness of 100–200 nm can have a high Voc and FF of up to 1.04 V and 0.74, respectively. This makes this device interesting for application as the first sub-cell in multi-junction devices. We fabricate two types of triple-junction (3J) solar cells, which consist of the second sub-cell of either a-Si:H (Eg≈1.7 eV) or nc-Si:H (Eg≈1.1 eV), with the nc-Si:H third sub-cell. In both 3J solar cells current mismatching can be reduced with a thin a-SiOx:H first sub-cell (≈100 nm) such that its high Voc×FF product can be fully used. An initial efficiency as high as 12.58% was obtained (Voc: 2.37 V, Jsc: 7.27 mA/cm2 and FF: 0.73) for the a-SiOx:H/a-Si:H/nc-Si:H 3J solar cell. This efficiency is competitive with the efficiency of other types of 3J solar cells. Pracoviště Fyzikální ústav Kontakt Kristina Potocká, potocka@fzu.cz, Tel.: 220 318 579 Rok sběru 2016
