تطوير أداء فيلم بيروكهربائي من ال PVDF في إنتاج الطاقة الكهربائية النظيفة

الملخص EN

A PVDF pyroelectric film was prepared by casting technology with a thickness of 3.9μm and active surface area of (3×3)mm2.

The electrical resistance and capacitance of the pyroelectric film were measured and they are respectively ?? ? ? ? .

The pyroelectric coefficient is measured by charge integration method.

It was 7=7><8

The mathematical study was carried out to define The energy conversion efficiency, then the results of the mathematical study were compared with the practical results.

The results showed that the best pyroelectric film thickness that achieves the highest energy conversion efficiency is d = 3.9μm, where the energy conversion efficiency is ? ? ? .

The results also showed that reducing the surface area of the pyroelectric film increases The energy conversion efficiency.

It was found that an external electrical resistance value must be ? .

The external capacitor should be removed
