Research output: Chapter in Book/Report/Conference proceedingConference contribution


Nanopillars can enhance solar cell performance, but the increased surface recombination often cancels performance gains. We demonstrate suppression of surface recombination through passivation of InP-pillar heterojunction solar cells, achieving a very high efficiency of 18.31%.
