Nanostructured materials and interfaces with novel optoelectronic functionalities play a key role in developing the new generation of solar cell and solar fuel devices. In this talk, I will highlight some of our recent results in understanding, interfacing and assembling different solution-processed nanomaterials for efficient solar energy conversion. First, I will focus on the design and construction of mesoscopic photoelectrodes, semiconductor quantum structures, donor-acceptor molecules, and metallo-organichalide films for sensitized solar cells and especially the most recently rising perovskite solar cells. Power conversion efficiency (PCE)of over 15% can now be readily obtained with low-cost materials and processes by judiciously designing the specific nanostructures and interfaces. Second, I will discuss our recent developments of various nanostructures and their suitable combinations for solar fuel generation devices, including nanostructured catalysts, photocatalysts, photoelectrochemical electrodes and light harvesters. One of the significant challenges ahead in engineering solar energy conversion devices is to understand the component nanostructure-function relationship, akin to the bonding-property relationship at the molecular level.
