Semiconductor nanostructures are attractive for designing low-cost solar cells with tunable photoresponse. The recent advances in size- and shape-selective synthesis have enabled the design of quantum dot solar cells with photoconversion e ﬃ ciencies greater than 5%. To make them competitive with other existing thin ﬁ lm or polycrystalline photovoltaic technologies, it is important to overcome kinetic barriers for charge transfer at semiconductor interfaces. This feature article focuses on the limitations imposed by slow hole transfer in improving solar cell performance and its role in the stability of metal chalcogenide solar cells. Strategies to improve the rate of hole transfer through surface-modi ﬁ ed redox relays o ﬀ er new opportunities to overcome the hole-transfer limitation. The mechanistic and kinetic aspects of hole transfer in quantum dot solar cells (QDSCs), nanowire solar cells (NWSCs), and extremely thin absorber (ETA) solar cells are discussed.

Biography
Prashant V. Kamat (center) is the Rev. John A. Zahm, C.S.C., Professor of Science in the Department of Chemistry and Biochemistry and Radiation Laboratory and concurrent professor in the Department of Chemical and Biomolecular Engineering. A native of Binaga, India, he earned his M.S. (1974) and Ph.D. degrees (1979) in physical chemistry from Bombay University and carried out his postdoctoral research at Boston University (1979–1981) and the University of Texas at Austin (1981–1983). He joined the Notre Dame faculty in 1983, where for over three decades he has worked to build bridges between physical chemistry and material science by developing advanced nanomaterials for cleaner and more efficient light energy conversion. He has published over 450 scientific papers, which have been well received by the scientific community (35 000+ citations), and has an h index of 103. He is the deputy editor of the Journal of Physical Chemistry Letters, on the advisory board of scientific journals Langmuir, Research on Chemical Intermediates, Journal of Colloid Science, and Applied Electrochemistry and Interface. Professor Kamat was awarded the Langmuir Lectureship award in 2013. In 2011, Science Watch of ISI included him among the top 100 chemists of the decade 2000–2010. He is a Fellow of the Electrochemical Society, American Association for the Advancement of Science (AAAS), and the American Chemical Society (ACS).
Biography
Jeffrey A. Christians (left) is a Ph.D. candidate in the Department of Chemistry and Chemical Engineering at the University of Notre Dame, where he studies under Prashant Kamat in the Notre Dame Radiation Laboratory. He earned his B.S. in chemistry and chemical engineering from Calvin College in 2010, where he researched single quantum dot biosensors for maltose detection. His current research focuses on hole-transfer processes in extremely thin absorber and perovskite photovoltaics.
Biography
James G. Radich (right) is a Ph.D. candidate in the Department of Chemical & Biomolecular Engineering at the University of Notre Dame, studying under Prashant Kamat in the Notre Dame Radiation Laboratory. He earned his B.S. and M.S. in chemical engineering from Mississippi State University, after which he spent several years working in a biotechnology research facility. James’ current interests are interfacial nanoscience as it relates to energy conversion and storage applications.
