“…An immense peak at an angle (22°) exhibited and indicated the amorphous structure of the Na-CMC spectra spectrum [4,13,14,15,16]. An amorphous feature at an angle (21°) manifested the SA pattern [4,17]. The blend manifests the immense band at 2θ = 21.6° that is allocated to the amorphous aura of the two virgin polymers [4,18].…”

ABSTRACT. Biopolymers are referred to the bio-degradable polymer that is derived from living organisms in nature or synthesized from renewable materials but needs polymerization. There are consisting of monomeric units that bond together through a covalent bond to obtain large molecules. A biopolymeric blend of sodium carboxymethyl cellulose/sodium alginate (Na-CMC/SA) film was prepared by the casting/solvent evaporation method. In addition to the molecular structure, the optical and molecular geometry of the collected films were characterized. XRD of binary blend investigated the interaction and miscibility among two biopolymers. FTIR of the blend spectrum explicated the conferring of the two polymer group’s vibrations. UV/Vis and optical studies appeared a peak in the binary at the wavelength (227 nm) which explained the high combination between two polymers. Molecular geometry clarifies the assignment of vibrational spectra of pure polymers which implied the important role of the (C=O) group as eventful regions for the two polymers.

“…Quantum dots are evaluated as sensitizers for quantum dot-sensitized solar cells (QDSSC) that have a working principle similar to that of DSSC except for the type of sensitizer and in some cases the electrolyte. Sulphide/polysulphide (S 2− /S n 2− ) can be used as an alternative to iodide/triiodide (I − /I 3 − ) redox couple, which could cause degradation of the quantum dot sensitizer and thereby compromise the solar cell e ciency (Baharun et al, 2019a). Furthermore, to ensure long-term stability of the electrolytes, their leakage and volatilization must be limited.…”

Organic waste-derived solar cells (OWSC) are a classi cation of third-generation photovoltaic cells in which one or more of its constituents are fabricated from organic waste material. They are an inspirational complement to the conventional thirdgeneration solar cell with the potential of revolutionizing our future approach to solar cell manufacture. This article provides a study and summary of solar cells that fall under the category of OWSC. OWSC own their merit to low cost of manufacturing and environmental friendliness. This review article reveals different organic waste raw materials, preparation-to-assembly methodologies and novel approaches to solar cell manufacturing. Ideas for the optimization of the performance of OWSC are presented. The assembly con gurations and photovoltaic parameters of reported OWSC are compared in detail. An overview of the trends pertaining to the research regarding OWSC in the past decade is given. Also, advantage and disadvantage of the different solar cell technologies are discussed and possible trends are proposed. Industrial organic waste raw materials such as paper, coal and plastics are amongst the least explored and yet most attractive for solar cell fabrication. The power conversion e ciencies for the cited works are mentioned while emphasizing the products and functions of the organic waste raw materials used.
