Abstract:
The sustainable and socioeconomic development of any country is based on reliable energy resources which are also to be considered as the lifeline of the country’s development. Pakistan is facing a severe energy crisis. Despite strong economic growth and rising energy demand during the past decade, some efforts have been made to install a new power plant for energy generation but have not achieved any sustainable development in this regard. The aim of this work is to utilize agricultural waste-based biomass like wheat straw to generate electricity in Punjab (PAKISTAN) to overcome the specter of load shedding and to fulfill energy demands in PAKISTAN. In this article, a detailed analysis of the production of wheat and wheat-straw has been debated. It is also studied that such field-based residues are a significant energy resource that can be used to generate electricity, based on clean energy technologies. In this paper, two biomass conversion technologies such as biomass gasification and biomass combustion are discussed in detail. It is also proposed one model village based on the wheat straw to fulfill the electricity demand of the village. Such proposed way can be implemented in the wheat rich areas. Therefore, in this paper, many recommendations have been reported for future consideration. Also, some clean energy-based technologies have been recommended which can lower environmental pollution and CO2. The potential of such waste/residues can be a sustainable source of income for the farmers as well as for the economy of the country. Therefore, some small units can be installed at the village level which can lower the overall energy crises. The impact of this research will be on the country economy, environmental friendly, and socio-economic.

Abstract:
Light-trapping phenomenon is limited due to non-uniform surface structure of transparent conducting oxide (TCO) films. The proper control of surface structure with uniform cauliflower TCO films may be appropriate for efficient light trapping. We report a light-trapping scheme of SF6/Ar plasma-based textured glass surfaces for high root-mean-square (RMS) roughness and haze ratio of ITO films. It was observed that the variation in Ar flow ratio in SF6/Ar plasma during the inductive coupled plasma-reactive ion etching (ICP-RIE) process was an important factor to improve the haze ratio of textured glass. The SF6/Ar plasma textured glass showed low etching rates due to the presence of various metal elements, such as Al, B, F, and Na. The ITO films were deposited on SF6/Ar plasma-textured glass substrates showed the high RMS roughness (433 nm) and haze ratio (67.8%) in the visible wavelength region. The change in surface structure has a negligible influence on the electrical properties of ITO films. The TCO films deposited on periodic textured glass surfaces with high RMS roughness and haze ratio are proposed for high-efficiency amorphous silicon (a-Si) thin-film solar cells.

Abstract:
The aim of this research work is to explore and compare electrochemical activity of the cupric sulfide (CuS) and cuprous sulfide (Cu2S) nanoparticles. For this purpose, CuS and Cu2S were synthesized by a facile chemical solution method. The morphology, structure, and surface area of the synthesized CuS and Cu2S nanoparticles were characterized by transmission electron microscope, X-ray diffraction, and Brunauer–Emmett–Teller analysis, respectively. The electrochemical activities of the prepared materials were studied by performing cyclic voltammetry and electrochemical impedance spectroscopy analysis in 1 M LiClO4 using a three-electrode system. It was observed that specific capacitance of the CuS (435 Fg−1) is higher than that of Cu2S (273 Fg−1) at the same current density (5 Ag−1). Furthermore, CuS retained 86% while Cu2S retained 75% of their initial capacitance after 6,000 charge–discharge cycles. Therefore, CuS owing to its higher electrochemical activity and cyclic stability is a superior electrode material than Cu2S for supercapacitor applications.
