X-ray photoelectron spectroscopy (XPS) is widely used to determine the chemical and
electronic states of atoms within a material. However, it is often complex to interpret the O 1s …

Bulk heterojunction (BHJ) polymer solar cells (PSCs) based on composites of conjugated
polymers (electron donor) and fullerene derivatives (electron acceptor) have attracted …

This study examined the origin of visible luminescence from ZnO layers deposited on p-Si
substrates by various growth methods using temperature dependent photoluminescence …

The influence of defects on the photoactivity of ZnO has been revealed. The defects can be
formed via ball-milling treatment, and part of the defects can be repaired via annealing …

Heterostructure construction, especially for anodes, is an effective strategy to promote
electron transfer and improve surface reaction dynamics, thus achieving high performance …
