How crystallinity of Tungsten Oxide governs the PEC efficiency and storage capacity

Graphical abstract: WO3 PEC efficiency governed by its crystallinity
Continuing from previous work on self-photorechargeability of Tungsten Oxide (WO3) for water splliting, the current work explores the importance of WO3 crystallinty in governing both PEC efficiency and storage capacity of flower structured WO3 electrode.
