title = "Effect of solvent environment on colloidal-quantum-dot solar-cell manufacturability and performance",
abstract = "The absorbing layer in state-of-the-art colloidal quantum-dot solar cells is fabricated using a tedious layer-by-layer process repeated ten times. It is now shown that methanol, a common exchange solvent, is the main culprit, as extended exposure leaches off the surface halide passivant, creating carrier trap states. Use of a high-dipole-moment aprotic solvent eliminates this problem and is shown to produce state-of-the-art devices in far fewer steps. {\textcopyright} 2014 WILEY-VCH Verlag GmbH & Co.
