Article Synopsis
- The paper presents the use of metal oxides, specifically nickel oxide (NiO) and titanium oxide (TiO), as carrier-selective contacts in ultrathin crystalline silicon solar cells, leading to about a 13% increase in efficiency.
- An ultrathin c-Si solar cell, only 2 μm thick, achieves efficiency over 10% without light-trapping, thanks to NiO's unique band offsets that reduce contact recombination.
- The integration process for both NiO and TiO is scalable and compatible with existing manufacturing techniques, enabling a champion efficiency of 10.8% when both materials are used.

Specifications in the Code of Federal Regulations for the color additive D&C Red No. 17 (Colour Index 26100) limit the levels of two subsidiary colors, 1-(phenylazo)-2-naphthol (Sudan I) and 1-[[2-(phenylazo)phenyl]azo]-2-naphthalenol (Sudan III o-isomer), to 3% and 2%, respectively. The present work reports the development of a high-performance liquid chromatography (HPLC) method for the quantitative determination of these subsidiary colors.
