TL;DR: It is demonstrated that efficiencies above 22% can be reached, even in thick interdigitated back-contacted cells, where carrier transport is very sensitive to front surface passivation, meaning that the surface recombination issue has truly been solved and black silicon solar cells have real potential for industrial production.

TL;DR: In this article, a review compiles four decades of light-induced degradation results in both electronic and solar-grade crystalline silicon, focusing on the properties and defect models of boron-oxygen LID and copper-related LID.

TL;DR: The combination of black silicon to improve the light absorption and negatively charged alumina to form an induced collecting junction characterizes a photodiode with external quantum efficiency above 96% between 250 µm and 950 µm.

TL;DR: In this paper, the authors demonstrate results that simultaneously show a huge improvement in the light absorption and in the surface passivation by applying atomic layer coating on highly absorbing silicon nanostructures.

TL;DR: In this article, a cost-efficient roadmap for industrial crystalline silicon solar cell production lines is presented, where the key processes of ozone-based ALD Al2O3 rear surface passivation and screen printed aluminum local back surface field are discussed in detail.
