- •
CdSe/CdS nanocomposites were coated on ZnO nanowires using solution processes.
- •
In situ CdSe/CdS co-sensitizers resulted in a 3-fold increase in efficiency.
- •
Nano-strain analyses at interfaces and CdS layers were performed.
- •
Drastic decrease of nano-strain in CdSe/CdS was observed.
- •
Relaxed nano-strain was attributed to the increase of efficiency.
