“…59 Comparable improved nanoscale phase separation was also demonstrated by Ahn et al, with controlled penetration of the acceptor through adjustment of the DCM:DCB cosolvent ratio for PC 61 BM. 177 Cosolvents also facilitate interdiffusion by optimizing the degree of polymer swelling (without dissolving the layer), as reported by Aguirre et al who used a blend of Tol and 2-chlorophenol (2-CP). 167 Solvent additives can also be exploited to tune the vertical phase separation.…”

“…The bulk heterojunction device [22][23][24][25] shows improved interfacial area where charge separation occurs as compared to bilayer device. Bulk heterojunction is prepared by bulk volume mixing of donor and acceptor components which results in very small exciton diffusion length at donor-acceptor interface [26].…”

Organic and dye sensitized solar cell devices have attracted a significant attention during last few years in scientific community due to their advantages such as low cost, easy processibility, large scale manufacturing and efficient conversion of solar energy into electrical energy. The main aim of this review is to provide torchlight for organic chemist willing to start exploration in the field of solar cell as it includes an overview of organic and dye sensitized solar cells. This review covers detailed history for development of solar cell, some basic terminologies used in organic and dye sensitized solar cells. The review article gives attention toward synthetic utility of organic molecules towards different types of solar cell such as single layer, double layer and bulk heterojunction solar cells, their mechanisms and type of materials which are generally used for solar cell device fabrication. The review specially gives focus on the up to date information about improvements in Organic Solar Cells (OSCs) and Dye Sensitized Solar Cells (DSSCs) which will be a handy tool for young budding researchers to explore the molecular engineering opportunities in terms of designing and synthesizing more efficient exotic materials for solar cell.

Polymeric Materials for Conversion of Electromagnetic Waves from the Sun to Electric Power

et al. 2018

Solar photoelectric energy converted into electricity requires large surface areas with incident light and flexible materials to capture these light emissions. Currently, sunlight rays are converted to electrical energy using silicon polymeric material with efficiency up to 22%. The majority of the energy is lost during conversion due to an energy gap between sunlight photons and polymer energy transformation. This energy conversion also depends on the morphology of present polymeric materials. Therefore, it is very important to construct mechanisms of highest energy occupied molecular orbitals (HOMO)s and the lowest energy unoccupied molecular orbitals (LUMO)s to increase the efficiency of conversion. The organic and inorganic solar cells used as dyes can absorb more photons from sunlight and the energy gap will be less for better conversion of energy to electricity than the conventional solar cells. This paper provides an up-to-date review on the performance, characterization, and reliability of different composite polymeric materials for energy conversion. Specific attention has been given to organic solar cells because of their several advantages over others, such as their low-energy payback time, conversion efficiency and greenhouse emissions. Finally, this paper provides the recent progress on the application of both organic and inorganic solar cells for electric power generations together with several challenges that are currently faced.
