“…In general, the aforementioned studies have confirmed the piezoelectric performance of ZnO nanostructures, and it is possible to fabricate piezoelectric ZnO-based structures without the need for high-voltage poling. On the other hand, ZnO nanomaterials have also found diverse applications in polymer solar cells [21] or other nanocomposite systems [22].…”

Piezoelectric transducers are becoming increasingly popular for dynamic strain monitoring due to their small form factors and their ability to generate an electrical voltage drop in response to strain. Although numerous types of piezoelectric thin films have been adopted for strain sensing, it has been shown that piezo-ceramics are expensive, brittle, and can fail during operation, while piezo-polymers possess lower piezoelectricity and mechanical stiffness. Thus, the objective of this study is to develop a piezoelectric thin film characterized by high piezoelectricity (i.e., high dynamic strain sensitivities) and favorable mechanical properties (i.e., being conformable to structural surfaces yet stiff). First, zinc oxide (ZnO) nanoparticles are dispersed in polyelectrolyte solutions, and the excess solvent is evaporated for thin film fabrication. The amount of ZnO nanoparticles embedded within the films is varied to yield seven unique sample sets with ZnO weight fractions ranging from 0 to 60%. Upon film fabrication, specimens are mounted in a load frame for monotonic uniaxial testing to explore the films' stressstrain performance and to subsequently determine their mechanical properties (namely, modulus of elasticity, ultimate strength, and ultimate failure strain). Finally, film specimens are also mounted onto cantilevered beams undergoing free vibration due to an applied initial displacement. The generated voltages in response to induced strains in the beams are recorded, and the piezoelectric performance and dynamic strain sensitivities for the different weight fraction films are calculated and compared. Commercial PVDF thin films are also employed in this study for performance comparison.

Kebutuhan untuk memperoleh sumber energi yang bersih dan terbarukan telah mendorong para peneliti untuk mengembangkan sel surya sebagai salah satu energi alternatif. Sel surya dengan bahan organik telah dikembangkan karena mempunyai potensi untuk diproduksi dengan biaya yang lebih murah, proses yang lebih mudah, dan dapat dikembangkan dengan substrat yang fleksibel/plastik. Salah satu pengembangan sel surya organik adalah sel surya polimer berbahan dasar polimer. Tulisan ini melaporkan hasil studi karakteristik listrik sel surya polimer hibrid menggunakan lapisan aktif campuran polimer P3HT dan semikonduktor ZnO diatas substrat fleksibel (PET). Sel surya polimer hibrid tersebut mempunyai struktur PET/ITO/PEDOT: PSS/P3HT-ZnO/Al dengan luas daerah aktifnya sebesar 2,6 cm 2 . Karakterisasi sifat listrik dilakukan dengan menyinari sel menggunakan sumber cahaya lampu xenon dengan intensitas penyinaran cahaya 270, 600, dan 1000 W/m 2 . Karakteristik listrik pada intensitas penyinaran 270 W/m 2 memiliki performansi yang paling baik dengan efisiensi konversi 0,024%, fill factor 0,63, tegangan open circuit sebesar 0,477 V, arus short circuit sebesar 5,6 × 10A, dan daya maksimum yang dihasilkan sebesar 1,68 × 10 −5 Watt. ABSTRACTNeed to obtain a source of clean and renewable energy has prompted researchers to develop solar cells as one of the alternative energy. Solar cells with organic materials have been developed as it has the potential to be produced at lower cost, easier to process, and can be developed with a flexible substrate/plastic. One is the development of organic solar cells polymer solar cells made from polymers. This paper reports the results of the study of electrical characteristics of hybrid polymer solar cells using P3HT polymer blend active layer and the semiconductor ZnO on flexible substrates (PET). The hybrid polymer solar cells have a structure of PET/ITO/PEDOT:PSS/P3HT-ZnO/Al with an area of 2.6 cm 2 active area. Characterization of the electrical properties is done by irradiating the cells using a light source with a xenon lamp light irradiation intensity 270, 600, and 1000 W/m 2 . Electrical characteristics at 270 W/m 2 irradiation intensity has the best performance with a conversion efficiency of 0.024%, 0.63 fill factor, open-circuit voltage of 0.477 V, short circuit current of 5.6 × 10 −5 A, and the maximum power result of 1.68 × 10 −5 Watt.

“…By probing the carrier dynamics at ZnO/P3HT interfaces, they have found that the interfacial molecules can play the role of assisting charge separation and suppression of back recombination at interfaces, which accounts for the observed enhanced short circuit current (Jsc) and open circuit voltage (Voc) in photovoltaic performance. Ji et al (2010) demonstrated a hybrid solar cell which was made by blending nanocrystalline ZnO and conjugated polymer regioregular P3HT as the active layer of the solar cell. It can be seen that the efficiency of this new type of solar cells obviously varied as the size and morphology of ZnO nanostructures.…”
