Abstract. In celebration of the 2015 International Year of Light, we highlight major breakthroughs in photonics for energy conversion and conservation. The section on energy conversion discusses the role of light in solar light harvesting for electrical and thermal power generation; chemical energy conversion and fuel generation; as well as photonic sensors for energy applications. The section on energy conservation focuses on solid-state lighting, flat-panel displays, and optical communications and interconnects.

“…[46][47][48][49] Inverse opal structured α-Fe 2 O 3 and Bi 2 WO 6 were constructed as photoanodes of PEC cells for efficient solar water splitting (Figure 2(f)). 40,46 The inverse opal-based photoanodes showed more than 2-fold enhanced photon-to-hydrogen conversion efficiencies of PEC water splitting as compared with the corresponding conventional films. The size and morphology control discussed in this section forms the basis for other strategies presented below.…”

Photoelectrochemical (PEC) water splitting to hydrogen is an attractive method for capturing and storing the solar energy in the form of chemical energy. Metal oxides are promising photoanode materials due to their low-cost synthetic routes and higher stability than other semiconductors. In this paper, we provide an overview of recent efforts to improve PEC efficiencies via applying a variety of fabrication strategies to metal oxide photoanodes including (i) size and morphology-control, (ii) metal oxide heterostructuring, (iii) dopant incorporation, (iv) attachments of quantum dots as sensitizer, (v) attachments of plasmonic metal nanoparticles, and (vi) co-catalyst coupling. Each strategy highlights the underlying principles and mechanisms for the performance enhancements.

Conversion of energy from photons in sunlight to hydrogen through solar splitting of water is an important technology. The rising signifi cance of producing hydrogen from solar light via water splitting has motivated a surge of developing semiconductor solar-active nanostructures as photocatalysts and photoelectrodes. Traditional strategies have been developed to enhance solar light absorption (e.g., ion doping, solid solution, narrow-band-gap semiconductor or dye sensitization) and improve charge separation/transport to prompt surface reaction kinetics (e.g., semiconductor combination, co-catalyst loading, nanostructure design) for better utilizing solar energy. However, the solar-to-hydrogen effi ciency is still limited. This article provides an overview of recently demonstrated novel concepts of nanostructure designs for efficient solar hydrogen conversion, which include surface engineering, novel nanostructured heterojunctions, and photonic crystals. Those fi rst results outlined in the main text encouragingly point out the prominence and promise of these new concepts principled for designing high-effi ciency electronic and photonic nanostructures that could serve for sustainable solar hydrogen production.
