Photoelectrochemical Hydrogen Production in Alkaline Solutions Using Cu2O Coated with Earth-Abundant Hydrogen Evolution Catalysts

Michael Graetzel, Xile Hu, Stanley David Tilley, Laurent Liardet, Carlos Gilberto Morales Guio, Matthew Thomas Mayer

The splitting of water into hydrogen and oxygen molecules using sunlight is an attractive method for solar energy storage. Until now, photoelectrochemical hydrogen evolution is mostly studied in acidic solutions, in which the hydrogen evolution is more fac ...

Low-Temperature Atomic Layer Deposition of Crystalline and Photoactive Ultrathin Hematite Films for Solar Water Splitting

Michael Graetzel, Marcel Roland Schreier, Ludmilla Steier, Matthew Thomas Mayer, Jingshan Luo

We developed a low-temperature atomic layer deposition route to deposit phase pure and crystalline hematite (alpha-Fe2O3) films at 230 degrees C without the need for postannealing. Homogenous and conformal deposition with good aspect ratio coverage was dem ...

Solution Transformation of Cu2O into CuInS2 for Solar Water Splitting

Michael Graetzel, Marcel Roland Schreier, Stanley David Tilley, Ludmilla Steier, Matthew Thomas Mayer, Jingshan Luo

Though Cu2O has demonstrated high performance as a photocathode for solar water splitting, its band gap is too large for efficient use as the bottom cell in tandem configurations. Accordingly, copper chalcopyrites have recently attracted much attention for ...

Efficient and selective carbon dioxide reduction on low cost protected Cu2O photocathodes using a molecular catalyst

Michael Graetzel, Mohammad Khaja Nazeeruddin, Marcel Roland Schreier, Thomas Moehl, Stanley David Tilley, Peng Gao, Matthew Thomas Mayer, Jingshan Luo

Photoelectrochemical reduction of CO2 to CO was driven by a TiO2-protected Cu2O photocathode paired with a rhenium bipyridyl catalyst. Efficient and selective CO evolution was shown to be stable over several hours. The use of protic solution additives to o ...

Water photolysis at 12.3% efficiency via perovskite photovoltaics and Earth-abundant catalysts

Michael Graetzel, Mohammad Khaja Nazeeruddin, Marcel Roland Schreier, Stanley David Tilley, Matthew Thomas Mayer, Jingshan Luo, Jeong-Hyeok Im

Although sunlight-driven water splitting is a promising route to sustainable hydrogen fuel production, widespread implementation is hampered by the expense of the necessary photovoltaic and photoelectrochemical apparatus. Here, we describe a highly efficie ...

Sub-Nanometer Conformal TiO2 Blocking Layer for High Efficiency Solid-State Perovskite Absorber Solar Cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Aravind Kumar Chandiran, Aswani Yella, Peng Gao, Matthew Thomas Mayer

A mere 2 nm conformal titanium dioxide overlayer coated by atomic layer deposition is shown to act as a blocking layer for high-efficiency solid-state perovskite (CH3NH3PbI3) absorber-based solar cells. Surpassing the existing multilayer passivation, this ...
