Lightweight flexible self-powered photo-supercapacitors with good stability through photoelectrochemical deposition of tellurium on PPy–V2O5 films as a new visible light active dual photoelectrode

Lightweight flexible solid-state photosupercapacitors (FSSPC) with two identical Te@PPy–V 2 O 5 photoelectrodes showed good performance and maintained functionality under different bending angles. They also demonstrated stability from −10 °C to 50 °C.
