Title: Hybrid photoelectrochemical and photovoltaic cells for simultaneous production of chemical fuels and electrical power

Abstract

Harnessing solar energy to drive photoelectrochemical reactions is widely studied for sustainable fuel production and versatile energy storage over different timescales. However, the majority of solar photoelectrochemical cells cannot drive the overall photosynthesis reactions without the assistance of an external power source. A device for simultaneous and direct production of renewable fuels and electrical power from sunlight is now proposed. This hybrid photoelectrochemical and photovoltaic device allows tunable control over the branching ratio between two high-value products of solar energy conversion, requires relatively simple modification to existing photovoltaic technologies, and circumvents the photocurrent mismatches that lead to significant loss in tandem photoelectrochemical systems comprising chemically stable photoelectrodes. Our proof-of-concept device is based on a transition metal oxide photoanode monolithically integrated onto silicon that possesses both front- and backside photovoltaic junctions. This integrated assembly drives spontaneous overall water splitting with no external power source, while also producing electricity near the maximum power point of the backside photovoltaic junction. The concept that photogenerated charge carriers can be controllably directed to produce electricity and chemical fuel provides an opportunity to significantly increase the energy return on energy invested in solar fuels systems and can be adapted to a variety of architectures assembled frommore » different materials.« less

Photoelectrochemical Hydrogen Production

Technical Report Hu, Jian

The objectives of this project, covering two phases and an additional extension phase, were the development of thin film-based hybrid photovoltaic (PV)/photoelectrochemical (PEC) devices for solar-powered water splitting. The hybrid device, comprising a low-cost photoactive material integrated with amorphous silicon (a-Si:H or a-Si in short)-based solar cells as a driver, should be able to produce hydrogen with a 5% solar-to-hydrogen conversion efficiency (STH) and be durable for at least 500 hours. Three thin film material classes were studied and developed under this program: silicon-based compounds, copper chalcopyrite-based compounds, and metal oxides. With the silicon-based compounds, more specifically the amorphous siliconmore »« less

Photoelectrochemical Hydrogen Production - Final Report

Technical Report Miller, E L ; Marsen, B ; Paluselli, D ; ...

The scope of this photoelectrochemical hydrogen research project is defined by multijunction photoelectrode concepts for solar-powered water splitting, with the goal of efficient, stable, and economic operation. From an initial selection of several planar photoelectrode designs, the Hybrid Photoelectrode (HPE) has been identified as the most promising candidate technology. This photoelectrode consists of a photoelectrochemical (PEC) junction and a solid-state photovoltaic (PV) junction. Immersed in aqueous electrolyte and exposed to sunlight, these two junctions provide the necessary voltage to split water into hydrogen and oxygen gas. The efficiency of the conversion process is determined by the performance of the PEC-more »« less

Anion Exchange Membrane for High Efficiency Solar-to-Hydrogen Generation

Technical Report Lattimer, Judith ; Strasser, Derek

The increasing availability of renewable energy sources, including solar, coupled with the desire to reduce greenhouse gas emissions, has led to an increased interest in using renewables to generate alternate energy sources. While the electricity produced by solar energy from photovoltaics can be used directly, intermittency and geographic limitations make it unfeasible to completely replace fuel sources that can be used whenever and wherever they are needed. Therefore, the ability to convert solar energy directly into chemical fuels, such as hydrogen, has garnered increasing attention over the past several decades. Hydrogen is an ideal fossil fuel alternative because it ismore »« less
Dye-sensitized photoelectrochemical water oxidation through a buried junction

Journal Article Xu, Pengtao ; Huang, Tian ; Huang, Jianbin ; ... - Proceedings of the National Academy of Sciences of the United States of America

Water oxidation has long been a difficulty in artificial photosynthetic devices that convert solar energy into fuels. Water-splitting dye-sensitized photoelectrochemical cells (WS-DSPECs) provide a modular approach for integrating light-harvesting molecules with water-oxidation catalysts on metal-oxide electrodes. Despite recent progress in improving the efficiency of these devices by introducing good molecular water-oxidation catalysts, WS-DSPECs have poor stability, owing to the oxidation of molecular components at very positive electrode potentials. In this work we demonstrate that a solid-state dye-sensitized solar cell (ss-DSSC) can be used as a buried junction for stable photoelectrochemical water splitting.

Direct in Situ Measurement of Charge Transfer Processes During Photoelectrochemical Water Oxidation on Catalyzed Hematite

Journal Article Qiu, Jingjing ; Hajibabaei, Hamed ; Nellist, Michael R. ; ... - ACS Central Science

Electrocatalysts improve the efficiency of light-absorbing semiconductor photoanodes driving the oxygen evolution reaction, but the precise function(s) of the electrocatalysts remains unclear. We directly measure, for the first time, the interface carrier transport properties of a prototypical visible-light-absorbing semiconductor, α-Fe₂O₃, in contact with one of the fastest known water oxidation catalysts, Ni_0.8Fe_0.2O_x, by directly measuring/controlling the current and/or voltage at the Ni_0.8Fe_0.2O_x catalyst layer using a second working electrode. The measurements demonstrate that the majority of photogenerated holes in α-Fe₂O₃ directly transfer to the catalyst film over a wide range of conditions and that the Ni_0.8Fe_0.2O_x is oxidized by photoholesmore »« less
