“…where R S is the sheet resistance, with 4.532 being the correction factor, V representing the voltage, and I is the current applied in the test unit [68]. Also, the I-V curves provide evidence that increasing 2,3-DHP causes a decline in the thin film sheet resistance to 0.38 Ω/,, which in turn increases the conductivity of the deposited PEDOT:PSS thin film.…”

Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) is one of the most promising hole transport layers that is widely used in high-performance optoelectronic devices. However, the hygroscopic nature and acidity of PEDOT:PSS is known to cause degradation in devices and decrease their performance. In this study, a new pyridine solid additive, 2,3-dihydropyridine (2,3-DHP) was incorporated into the PEDOT:PSS solution to improve its characteristics. A low-temperature solution-based spin-coating device was utilized to produce the thin films. From the results, the PEDOT:PSS@2,3-DHP (1 wt%) exhibited excellent optical characteristics. It also provided informative and controlled morphology when it was annealed at 100 oC, suggesting that PEDOT:PSS@2,3-DHP has a potential advantage in photovoltaic (PV) devices. Moreover, in the photodetection experiment utilizing LED of 380 nm, PEDOT:PSS@2,3-DHP showed a higher photocurrent response when compared with pristine PEDOT:PSS. It also significantly reduced sheet resistance and achieved superior electrical conductivity. Interaction between the 2,3-DHP, PEDOT, and PSS chains altered the mechanical properties of the PEDOT:PSS, leading to the modification in structural and electrical characteristics. Overall, these findings highlight the importance and applicability of PEDOT:PSS@2,3-DHP in a wide range of optoelectronic devices.

“…The Hall Effect is used to determine the kind of majority charge carriers, Hall mobility (µH), and concentration in CdSe thin films deposited at room temperature (nH). The Hall effect was next explored, and the Hall coefficient was derived with the use of an equation [16].

CdSe nanocrystalin thin films were deposited onto silicon wafer using DC plasma sputtering method. Quantification of the crystalline size of CdSe thin films has been achieved by X-ray diffraction (XRD) technique. Otical properties of prepared CdSe thin films including absorption coefficient and optical band gap, have been analyzed and evaluated in the wavelength range of 250-850 nm. In addition, the current-voltage characteristics of a CdSe/Si hetero-junction have been examined, and the results show that lighting causes an increase in photo-current. The open circuit voltage was 2.0 V and the short circuit current was 0.18 mA. The abbreviation open circuit current is Voc.

“…The conductivity for both sampleswas found to increase with increase in temperature. This happened because the samples absorbed heat which is converted to electrical energy (Laily et al, 2016). The highest conductivity is 183 Scm -1 at 100°C obtained from the sample of dragon fruit dye extracted with distilled water.…”

Natural pigments such as anthocyanin, carotenoid, flavonoids, and chlorophyll can be considered as promising alternative sensitizer dyes for DSSC to replace synthetic dye such as N719 because of their simple preparation technique, low cost, complete biodegradati on, availability, purity grade, environmental friendliness and most importantly ability to reduce noble metal. In this work, UV-Vis spectra is used to observe the absorption spectra of different extracting solvent of dragon fruit dye. Fourier Transform Infrared Spectroscopy (FTIR) identifies the functional components of the dye while impedance spectroscopy gives the conductivity data. Dragon fruit dye extracted with ethanol had a lower absorbance at 518 nm compared to dragon fruit dye extracted with distilled water at 521 nm. The presence of carboxyl group in Betalains pigment within the range of 400 -700 nm wavenumber promotes strong hydrogen bonding while the presence of COOH stretching vibration further confirms the carboxyl group of Betalains derivatives in dragon fruit dye. The electrical conductivity measured at room temperature (27°C), boiling point (100°C) and 130°C recorded highest value of 183 Scm -1 at 100 °C for dragon fruit dye diluted with distilled water (D-DI) while for dragon fruit dye diluted with ethanol (D-Etha) the value is 9.56 × 10 -1 Scm -1 at 130°C hence showing that distilled water is the best solvent for natural dye from dragon fruit.
