The field of organic photovoltaics has developed rapidly over the last 2 decades, and small
solar cells with power conversion efficiencies of 13% have been demonstrated. Light …

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 …

All‐polymer solar cells (all‐PSCs) exhibit excellent stability and readily tunable ink viscosity,
and are therefore especially suitable for printing preparation of large‐scale devices. At …

The importance of morphology to organic solar cell performance is well known, but to date,
the lack of quantitative, nanoscale and statistical morphological information has hindered …

The device function of polymer bulk heterojunction (BHJ) solar cells has been commonly
interpreted to arise from charge separation at discrete interfaces between phase-separated …

The performance of polymer: fullerene bulk heterojunction solar cells is heavily influenced
by the interpenetrating nanostructure formed by the two semiconductors because the size of …

The performance of organic solar cells is highly dependent on film morphology. However,
directly correlating local film structures with device performance remains challenging. We …

Solution-processable small molecules have attractive features for application in photovoltaic
cells. They offer the facile processing associated with polymers, yet are easier to synthesize …

Near Edge X-ray Absorption Fine Structure (NEXAFS) spectromicroscopy, resonant
scattering and resonant reflectivity are specialized, synchrotron radiation based, soft X-ray …
