Polymer Solar Cells: Miscibility-Function Relations in Organic Solar Cells: Significance of Optimal Miscibility in Relation to Percolation (Adv. Energy Mater. 28/2018)

Polymer-polymer miscibility

The theoretical and practical aspects of polymer-polymer miscibility in the solid amorphous state are reviewed. The polymers include homopolymers and both random and block copolymers. Although present theoretical treatments of polymer-polymer miscibility all contain the random mixing hypothesis and are thus not applicable to mixtures that involve specific interactions between the components, mo...

Conjugated polymer-based organic solar cells.

Photovoltaics (PVs) consists of the harvesting of energy from sunlight and its conversion into electrical power. This technology is being increasingly recognized as one of the key components in our future global energy scenario. Limited fossil fuel resources and steadily increasing costs of supplying fossil fuels to the market induce a natural limit where renewable energies will begin to kick i...

Enhance performance of organic solar cells based on an isoindigo-based copolymer by balancing absorption and miscibility of electron acceptor

Introduction to polymer solar cells

New photovoltaic (PV) energy technologies can contribute to environmentally friendly, renewable energy production, and the reduction of the carbon dioxide emission associated with fossil fuels and biomass. One new PV technology, plastic solar cell technology, is based on conjugated polymers and molecules. Polymer solar cells have attracted considerable attention in the past few years owing to t...

A simple approach to polymer mixture miscibility

Polymeric mixtures are important materials, but the control and understanding of mixing behaviour poses problems. The original Flory-Huggins theoretical approach, using a lattice model to compute the statistical thermodynamics, provides the basic understanding of the thermodynamic processes involved but is deficient in describing most real systems, and has little or no predictive capability. We...
