“…Since its initial conception in 1991 by Gratzel and O'Regan [100], the DSSC has been a continually attractive method for converting solar light to electric power and has been the subject of many investigations [101][102][103][104][105][106][107]. This considerable interest into the DSSC is a result of its many advantages over traditional solar cell technologies, such as low production cost, simple fabrication methods, easy scale-up ability, architectural and environmental compatibility as well as good performance under weak/diffuse light [108].…”

Functional thin films provide many opportunities for advanced glazing systems. This can be achieved by adding additional functionalities such as self-cleaning or power generation, or alternately by providing energy demand reduction through the management or modulation of solar heat gain or blackbody radiation using spectrally selective films or chromogenic materials. Self-cleaning materials have been generating increasing interest for the past two decades. They may be based on hydrophobic or hydrophilic systems and are often inspired by nature, for example hydrophobic systems based on mimicking the lotus leaf. These materials help to maintain the aesthetic properties of the building, help to maintain a comfortable working environment and in the case of photocatalytic materials, may provide external pollutant remediation. Power generation through window coatings is a relatively new idea and is based around the use of semi-transparent solar cells as windows. In this fashion, energy can be generated whilst also absorbing some solar heat. There is also the possibility, in the case of dye sensitized solar cells, to tune the coloration of the window that provides unheralded external aesthetic possibilities. Materials and coatings for energy demand reduction is highly desirable in an increasingly energy intensive world. We discuss new developments with low emissivity coatings as the need to replace scarce indium becomes more apparent. We go on to discuss thermochromic systems based on vanadium dioxide films. Such systems are dynamic in nature and present a more sophisticated and potentially more beneficial approach to reducing energy demand than static systems such as low emissivity and solar control coatings. The ability to be able to tune some of the material parameters in order to optimize the film performance for a given climate provides exciting opportunities for future technologies. In this article, we review recent progress and challenges in these areas and provide a perspective for future trends and developments.

“…Light-harvesting in Grätzel DSCs typically makes use of ruthenium(II) complexes [1,2], but their replacement by organic dyes [3] or metal complexes incorporating Earthabundant metals [4] is advantageous in the interests of establishing a cheaper and more sustainable technology. We and others are focusing both our experimental and theoretical attention on dyes in which the chromophore is a copper(I) complex [4,5,6,7,8,9,10] Copper(I) diimine complexes are labile and the rapid ligand exchange processes [ 11 ] predicate against the isolation of chemically pure heteroleptic complexes, making this a challenging goal [12].…”

The recognition of this lability allowed us to develop a method of assembling TiO 2 -bound heteroleptic [Cu(L anchor )(L ancillary )] + dyes directly on a surface [4]. The diimine ligand L anchor is typically functionalized with carboxylic or phosphonic acid groups, with the latter exhibiting enhanced binding and temporal performance over the former [13].…”
