Analysis of charge transport resistance of ZnO-based DSSCs because of the effect of different compression temperatures

AIP Advances, Journal Year: 2023, Volume and Issue: 13(9)

Published: Sept. 1, 2023

This article represents a research study about the effect of compression temperature on performance Zinc Oxide (ZnO)-based dye-sensitized solar cell (DSSC). To find optimum temperature, electrodeposited photoanodes are subjected to at 60 MP with various temperatures ranging from room 80 °C. The analysis involved Electrochemical Impedance Spectroscopy (EIS) and photocurrent-voltage (I-V) data under dark illuminated conditions. EIS examined gain insights into electron transport mechanism validate cell's temperature. findings this demonstrate that cells prepared 70 °C show most favorable photovoltaic compared other temperatures. Thickness measurement confirms increasing ensures compact layer photoelectrode. A greater than causes several defects photoelectrode surface, as confirmed by Scanning Electron Microscopy Image. I-V confirm heating gives comparatively lower series resistance higher shunt resistance. Though exhibited different values illumination conditions, their trends remained consistent. Under optimized achieved maximum efficiency (η) 2.78%, accompanied an open circuit voltage (Voc) 0.58 V, photocurrent density (Jsc) 8.87 mA/cm2, fill factor 0.54.

Impact of calcination temperature on optimized NiO anode synthesis for batteries

Materials Science and Technology, Journal Year: 2024, Volume and Issue: unknown

Published: July 25, 2024

In this research, NiO, a vital transition metal known for its excellent electrochemical properties, was successfully synthesized under alkaline conditions using the precipitation method. Alterations in calcination temperatures between 720 and 800°C an argon atmosphere yielded different NiO crystal sizes. The smallest crystals, obtained at 760°C, exhibited highest specific capacity, reaching 991.2 mAh g –1 0.5 C. electrode showed impressive capacitance retention rate of approximately 98% over 300 cycles. This method offers high-performance materials with extended life cycles, making it strong candidate use lithium-ion battery anodes. Using saturated potassium hydroxide (KOH) aids nickel oxide precipitation, improving performance. Recyclable KOH enhances potential large-scale anode material production.
