“…BiVO4 [30,31] and in particular nano-structured BiVO4 [32,33,34], are attractive photo-anode materials for photo-catalysis and water splitting applications, but the effect of Al2O3 over-layers has not been reported previously. We have recently reported a simple "one-step" approach for the formation of BiVO4 from a paint precursor applied to tin-doped indium oxide (ITO) substrates [35] and for application of BiVO4 coatings onto titanium substrates [36].…”

Fx1 Highlights: • Thin alumina barrier coating can enhance photo-activity of bismuth vanadate photoanode materials • There are two distinct potential domains with different enhancement characteristics and mechanisms • The thickness of alumina films can be controlled with a sol-gel coating to provide optimized performance Abstract Nanostructured semiconductor photoanodes play an important role in solar fuel generation, and the design of the semiconductor -aqueous electrolyte interface can be crucial in enhancing the energy conversion efficiency. We have investigated the effects on photoelectrochemical oxygen evolution for monoclinic nanostructured BiVO4 films uncoated and coated with microporous sol-gel Al2O3 "over-layers". Variation of the thickness of the Al2O3 coating (formed by surface sol-gel deposition and annealing at 435 o C) led to a reduction of pseudo-capacitance and allowed optimization of the quantum efficiency. Exploration of the photocurrent enhancement as a function of applied potential reveals two distinct potential domains/mechanisms: (i) a low bias region enhancement effect (assigned to a lowering of the rate of external recombination of electrons with oxygen) and (ii) a high bias region of enhancement (assigned to higher charge carrier mobility due to less trapping in surface states).

Inorganicbased window solutions, including metallic based reflective layers, [28][29][30][31] photochromic, [3,32,33] electrochromic, [3,8,[34][35][36][37][38][39] and thermochromic [3,[40][41][42][43] systems, plasmonic nanoparticles, [36,[44][45][46] aerogel glazing, [47] privacy windows, [48] thin film photovoltaics, [49] and even microfluidic [50] based windows have not been discussed in this review, as they have already received considerable attention and discussion. Additionally, organic based window devices and materials primarily intended to absorb and control visible light passage, including electro-, [51][52][53] photo-, and thermochromic [3] windows, are also beyond the scope of this review of infrared control materials: they have already been detailed in a number of excellent review articles.…”

(IR), here defined as light with wavelengths between 700 nm and 2500 nm, accounts for around 50% of the total energy emitted by the sun reaching Earth (Figure 1b), [3,4] and this light produces interior heating but is invisible to the unaided eye.The absorption of sunlight by building materials and passage of IR through transparent surfaces such as windows is responsible for much of the interior overheating of office rooms, automobile interiors, greenhouses, and other similar spaces. The use of artificial cooling and heating systems will only increase with the continued influence of global climate change, with energy used for cooling systems surpassing energy used for heating around the year 2070, and a 40 fold increase in air cooling energy use is expected by 2100. [5] By controlling the influx of radiant heat transfer, calculations show that more than 50% of the energy used in lighting, heating and cooling could be saved by deploying better control systems over only 18% of available window stock. [6] In areas with human inhabitants employing windows, more aspects must be considered than simply reducing the use of energy in the room: any switchable window used in, for example, a commercial office space has several other requirements that must be met before it may be installed. Among these requirement are reasonably fast switching speeds [7] (although for IR control, relatively longer times compared to visible light switching should be acceptable), good optical transparency with minimum haze, an acceptable device lifetime, [8] and functionality over a range of exterior temperatures. Controlling the excess of solar energy without compromising the visible transparency of the window is an important consideration for human health: maintaining inside/outside contact and daylighting are vital in retaining well-being and productivity, as well as providing economic and aesthetic gain by reducing the need for artificial lighting systems. [9,10] These are challenging goals for a window to realize.A number of materials have been developed over the past few decades to maintain indoor temperatures. Many of these focus on the opaque structural building elements like walls and roofing. [10][11][12][13] Other solutions target the transparent window, employing external mechanical shutters and blinds, [14] phase change materials (PCMs), [15] thermochromic materials, [16] aerogels, [17] trapped gas in fluid membranes, [18] and even phononic materials, [19] among other options. Indeed, controlling heat passage through the window in response to changing climate conditions is a great challenge; ideally, one would accomplish Windows are vital elements in the built environment that have a large impact on the energy consumption in indoor spaces, affecting heating and cooling and artificial lighting requirements. Moreover, they play an important role in sustaining human health and well-being. In this review, we discuss the next generation of smart windows based on organic materials which can change their properties by reflecting or trans...
