We reveal that ambient water plays an essential role in surface hydroxylation, epitaxial QDs fusion, and trap behavior in QD photovoltaics. By manipulating the deposition techniques and film morphology, the side effect of ambient water on CQD solar cells can be effectively suppressed.

Using an innovative cell architecture utilizing nanoengineered cathode layers, we report attainment of superior current densities for anode-supported solid oxide fuel cells.

Disorder in the energies of charge-transfer (CT) states can be induced by the complex phase behaviour of bulk heterojunctions in organic semiconductors. Here, we propose a model to help to quantify and understand the impact of CT state energetic disorder on voltage losses in organic photovoltaics.

In our recent paper (Nature Communications, 2021, 12:3260), we reported the experimental study on defect properties of antimony trisulfide (Sb2S3). Here I highlight the critical issues regarding the sample preparation, unique defect properties and the significance to device performance improvement.
