Technical FAQs 4

Why is PVDF used in photovoltaic systems?

In addition, the PVDF retains in the crystal boundary and surface of perovskite film which can coat and fill into the vacancy to greatly reduce bulk defects of perovskite crystal and contributes to the improvement of photovoltaic performances and stability.

What is PVDF (vinylidene fluoride)?

Poly (vinylidene fluoride) (PVDF) (1, 2 and 4 mg/mL) was dissolved in mixed solvent before spin-coating. Perovskite solar cells were prepared on etched fluorine-doped tin oxide (FTO) glass, which was cleaned with ultra-pure water and ethanol, and then sintered on the hot plate.

Is 2 mg/mL PVDF a good photovoltaic device?

As a result, the perovskite device with 2 mg/mL PVDF displays the excellent photovoltaic performances, yielding an increased PCE from 19.32% for control to 21.42% and the slight hysteresis phenomena.

What are the advantages of PVDF vs PSCs?

The PSCs with PVDF present meaningfully improved humidity and thermal resistance. Perovskite solar cells (PSCs) have become the promising next-generation photovoltaic devices due to their excellent photoelectric performances, and the power conversion efficiencies (PCEs) have experienced unprecedented rapid increase in recent years.
