Efficient charge collection is important for achieving high conversion efficiency in solar cells. On p. 829 Hyun Suk Jung, Jin Young Kim, and coworkers show that three-dimensional transparent conducting oxide (TCO) substrates based on aligned In-Sn-O (ITO) nanowire arrays provide a universal strategy for improving charge collection properties of solar cells by significantly reducing the charge travel distance in the active material.
