“…On extraction, APPE yielded a pinkish colour whereas APPE-AgNPs yielded a yellowish-brown colour. The colours of APPE and APPE-AgNPs obtained were similar to those reported by Uren [13] and Adebayo [14] respectively. At the beginning of the reaction between APPE and AgNO 3 , the mixture yielded a light pink colour; after 1 h of reaction, the colour developed to yellowish-brown and remained the same even after 6 hours of observation and when kept overnight.…”

This work was designed to evaluate the unmodified and modified natural dye obtained from a sensitizer in dye-sensitized solar cells using experimental and computational approaches. Natural dye (APPE) was extracted from Avocado pear (Persea Americana) peels and chemically modified into nanocomposite by a one-pot reaction with silver nitrate. The modified dye was characterized by UV-Vis spectroscopy, X-ray diffraction (XRD) spectroscopy, Energy dispersive spectroscopy (EDS) and transmission electron microscopy (TEM). The APPE and APPE-AgNPs composite show maximum wavelength of light absorption at 542 nm and 493 nm respectively. Both APPE and APPE-AgNPs were evaluated as sensitizers for dye-sensitized solar cells (DSSC). The APPE-AgNPs dye afforded a higher power conversion efficiency of 0.93% compared to 0.44% for APPE. Current-voltage responses and photo-electrochemical properties were determined at one sun illumination. The electronic properties of the major phyto-compounds in the dye, namely perseorangin and cyanidin associated with light harvesting and sensitization were modeled using a quantum chemical computational approach. The power conversion efficiency of APPE-AgNPs obtained from this study compares with other plant-based dye sensitizers and hence could be deployed for practical application.

“…The ultraviolet–visible measurements are used here to evaluate the energy band gap of the powder and recrystallized perovskite material. [ 12 ] The band gap ( E g ) is calculated by using the absorption spectra curve as shown in Figure . Figure 3a shows the calculated band gap of CH 3 CH 2 NH 3 PbI 3 is 2.79 eV while the calculated band gap of CH 3 NH 3 PbI 3 is 1.58 eV (Figure 3b).…”

Perovskite solar cells have appeared as a leading next‐generation photovoltaic technology. However, notwithstanding rolling efficiencies, many questions remain unreciprocated regarding the mechanisms and performance of the operation. Solution‐processed organic‐inorganic hybrid perovskites have fascinated attention as light‐harvesting materials for perovskite solar cells and photonic applications. The present study focuses on the optical and electronic study of CH3NH3PbBr3 and CH3CH2NH3PbI3 perovskite fabricated by a one‐step solution‐based self‐assemblage method. It is seen that in this study, methyl group represents a better performance than ethyl‐based perovskite‐sensitized solar cells (PSSCs). All the studies centralize on electro‐optical properties of efficient CH3CH2NH3PbI3 and CH3CH2NH3PbI3 PSSC based on polymer electrolytes. It has also characterized lab synthesized perovskite samples by scanning electron microscopy (SEM), UV–vis spectrophotometer, and photovoltaic performance of lab fabricated PSSC is measured by Keithley 2400 resource meter. These findings establish systematic strategy rules to attain silicon‐like efficiencies in simple perovskite solar cells.

“…However, gas‐permeable OECTs having both gas‐permeable SPE and channel layer have not been realized. Conventionally, a solid polymer is formed by drying the polymer solution, and heat is used to remove the solvent [ 26–29 ] After the drying process, SPEs are formed in continuous film structures. Although mass‐permeable quasi‐solid hydrogels have been reported to achieve better skin/electronic interfaces [ 30 ] and drug delivery applications, [ 31–33 ] neither gas‐permeable solid‐state electrolytes nor gas‐permeable solid‐state electrolyte‐embedded OECTs have not been reported.…”

Fibrous nanomesh organic electrochemical transistors (OECTs) embedded with porous solid‐state polymer electrolytes (SPE) are developed for use as on‐skin active electrodes. The OECTs exhibit a microporous structure, which makes them gas permeable, allowing for the evaporation of sweat vapor when they are in conformable contact with the skin. The non‐volatility of the SPE allows for the long‐term functionality of organic electrochemical transistors. The superior electrical characteristics of the OECT can be utilized to locally amplify on‐skin bio‐potential signals. The acquisition of high‐quality electrocardiogram signals is demonstrated in this study. This porous transistor‐type on‐skin active electrode enables the long‐term acquisition of high‐quality electrophysiological signals.
