The bulk-heterojunction blend of an electron donor and an electron acceptor material is the
key component in a solution-processed organic photovoltaic device. In the past decades, a p …

The performance of organic solar cells (OSCs) depends on a fine, carefully optimized bulk-
heterojunction (BHJ) microstructure. The understanding and manipulation of BHJ …

Undesirable efficiency reproducibility was sometimes observed in fabrication of high
performance polymer solar cell devices incorporating high boiling point additives. The …

X-ray diffraction has been a standard technique for investigating structural properties of
