“…The justification for applying BCPs to photovoltaics was explained in the Introduction, and much of the work was reviewed recently [25,65,66]. The polymers used for photovoltaic applications usually have a conjugated backbone on which the molecular orbitals are delocalized.…”

Nanostructures generated from block copolymer self-assembly enable a variety of potential technological applications. In this article we review recent work and the current status of two major emerging applications of block copolymer (BCP) nanostructures: lithography for microelectronics and photovoltaics. We review the progress in BCP lithography in relation to the requirements of the semiconductor technology roadmap. For photovoltaic applications, we review the current status of the quest to generate ideal nanostructures using BCPs and directions for future research.

“…Following on from this, the self-assembling behavior of block copolymers is discussed before focusing on the different strategies taken to synthesize, utilize, and process block copolymers. There are a number of reviews in the literature that cover various aspects of the use of block copolymers in optoelectronics 33 and photovoltaics, 34 and also the challenges faced when using block copolymers in such devices, 35 the various active donor-acceptor systems used, 36 conjugated block copolymer behavior, [37][38][39] and nanostructural considerations. 40 Here, we have constructed a review for readers new to the field of OPVs in an attempt to stimulate progress toward highly efficient block copolymer-based devices.…”

A simple overview of the methods used and the expected benefits of block copolymers in organic photovoltaic devices is given in this review. The description of the photovoltaic process makes it clear how the detailed self-assembly properties of block copolymers can be exploited. Organic photovoltaic technology, an inexpensive, clean and renewable energy source, is an extremely promising option for replacing fossil fuels. It is expected to deliver printable devices processed on flexible substrates using high-volume techniques. Such devices, however, currently lack the long-term stability and efficiency to allow organic photovoltaics to surpass current technologies. Block copolymers are envisaged to help overcome these obstacles because of their long term structural stability and their solid-state morphology being of the appropriate dimensions to efficiently perform charge collection and transfer to electrodes.

“…Dendritic nanostructures are promising candidates for a variety of applications, such as the next-generation electrocatalysts [1], photovoltaic cells [2][3][4], supercapacitors [5] or sensing devices [6,7]. Metallic nanostructures of this kind are also used as surface enhancement Raman scattering (SERS) active surfaces, for which new techniques based on thermal annealing have been recently developed [8].…”
