PV power generation includes PV power generation and grid-connected PV power generation, and the scope of this paper focuses on solar energy harvesting technologies for PV self-powered applications, which belongs to the former scope. There are many studies on PV self-powered technologies, but there has been no review of this field.
Recently, self-assembled materials (SAMs) have garnered significant interest for their utility as hole-selective layers (HSLs) within inverted perovskite solar cells (IPSCs) and in the construction of perovskite-based tandem solar cells, as documented in references 1, 2, 3, 4.
However, solute accumulation at the heating interface has severely impacted the performance and long-term stability of current solar evaporation systems. Here, a self-regenerating solar evaporator featuring excellent antifouling properties using a rationally designed artificial channel-array in a natural wood substrate is reported.
This review classifies PV self-powered applications into four categories based on application scenarios: PV self-powered for personnel wearable devices, PV self-powered for transportation, PV self-powered for household & building systems, PV self-powered for environmental monitoring equipment.
PV self-powered system, the energy comes from solar energy, and the power supply for power applications is guaranteed. Also, PV self-powered systems are a more reliable way to supply power than conventional battery power supply.
Wei et al. proposed a mechanical and solar energy-driven self-powered hybrid system for hydrogen production. Mechanical energy is obtained from water using a rotating disc-shaped frictional electric nanogenerator.
