The development of organic semiconductors for photovoltaic devices, over the last three
decades, has led to unexpected performance for an alternative choice of materials to convert …

This review highlights recent efforts on applying electron microscopy (EM) to soft (including
biological) nanomaterials. We will show how developments of both the hardware and …

Organic photovoltaic (OPV) technology has been developed and improved from a fancy
concept with less than 1% power conversion efficiency (PCE) to over 10% PCE, particularly …

Organic semiconductors offer the potential for large-area deposition on substrates of flexible
or unique form factors and can be deposited at ambient conditions at low cost. They can be …

Organic solar cells have the potential to be low-cost and efficient solar energy converters,
with a promising energy balance. They are made of carbon-based semiconductors, which …

The rapidly expanding field of polymer and organic solar cells is reviewed in the context of
materials, processes and devices that significantly deviate from the standard approach …

The performance of solution processed polymer: fullerene thin film photovoltaic cells is
largely determined by the nanoscopic and mesoscopic morphology of these blends that is …

The contact between the polymer active layer and the electrode is one the most critical
interfaces in polymer solar cells. In this article, we report the progress of interface …

We review the morphologies of polymer‐based solar cells and the parameters that govern
the evolution of the morphologies and describe different approaches to achieve the optimum …

Recently, significant advances have been made in understanding and manipulating the
morphology of the active layer in bulk heterojunction (BHJ) organic photovoltaic (OPV) …
