Dual-Absorber Solar Cell Design and Simulation Based on SbSe and CZTGSe for High-Efficiency Solar Cells.

Inorganic solar cells based on the binary-type metal chalcogenide semiconductor, particularly SbSe, have recently garnered significant interest due to their abundant and nontoxic natural elements, strong thermal stability, and favorable optoelectronic properties. Single-absorber solar cells using antimony selenide have been the most common choice to date but have shown only limited efficiency in converting sunlight into electricity. The primary aim of this research is to examine a device structure that demonstrates an enhanced efficiency.

Impact of absorber layer thickness, defect density, and operating temperature on the performance of MAPbI solar cells based on ZnO electron transporting material.

Hybrid organic-inorganic perovskite solar cells (PSCs) are the novel fourth-generation solar cells, with impressive progress in the last few years. MAPbI is a cost-effective material used as an absorber layer in PSCs. Due to the different diffusion length of carriers, the electron transporting material (ETM) plays a vital role in PSCs' performance.

Magneto-Electric Effect on Guided Waves in Functionally Graded Piezoelectric⁻Piezomagnetic Fan-Shaped Cylindrical Structures.

Functionally graded piezoelectric⁻piezomagnetic (FGPP) material simultaneously consists of piezomagnetic and piezoelectric phases, which are able to convert energy among mechanical, electric, and magnetic fields. The magneto-electric effect on waves in FGPP fan-shaped cylindrical structures is studied by exploiting the double Legendre orthogonal polynomial method. By means of the Heaviside function, the initial conditions are brought into wave motion equations.

Wave propagation in the circumferential direction of general multilayered piezoelectric cylindrical plates.

The Legendre polynomial approach has been proposed to solve wave propagation in multilayered flat plates and functionally graded structures for more than ten years, but it can deal with a multilayered plate only when the material properties of two adjacent layers do not change significantly. In this paper, an improvement of the Legendre polynomial approach is proposed to solve wave propagation in what, from now on, we will call general multilayered piezoelectric cylindrical plates, to mean indifferently with or without very dissimilar materials. Detailed formulations are given to highlight the differences from the conventional Legendre polynomial approach.
