“…[1][2][3][4][5][6]. Significant successes in this field are associated with the possibility of chemical-technological modification of elements based on chalcogenide glasses GeS 2 -Ga 2 S 3 through components that give new properties [7][8][9][10][11]. Thus, the basic functionality of glasses can be effectively combined with the high transparency of halides in the visible part of the spectrum, creating mixed chalcogenide-halide glasses [12][13][14][15].…”

Modification of free-volume positron trapping defects in the GaS 2 -Ga 2 S 3 -CsCl chalcogenide glasses was studied using positron annihilation lifetime spectroscopy and Doppler broadening of annihilation radiation methods. It is shown that the addition of CsCl to the main glass matrix leads to agglomeration of internal free-volume defects, which are di-or tri-atomic vacancies. However, an excessive amount of CsCl component causes a decrease in the size and content of these defects in the internal structure of the glass against the background of water adsorption in nanovoids with a radius of 0.3 nm. The obtained results are confirmed by normal and abnormal trends in the correlation of the S parameter, which characterizes the annihilation of positrons with low-momentum valence electrons and the W parameter, which corresponds to the annihilation of positrons with high-momentum core electrons.

“…Among all kinds of new clean energy, solar energy is considered to be one of the most promising clean energy sources. [1][2][3][4][5][6] Photovoltaic conversion is an important way to convert solar energy into electricity based on light trapping effect. [7][8][9][10][11] However, crystalline silicon (c-Si) solar cells have low absorption of photons near the bandgap.…”

In this paper, a high‐efficiency silicon‐based thin‐film solar cell is proposed based on double‐layer nano‐pyramid (DNP) arrays. In the model, the surface and bottom of the silicon photovoltaic layer are embedded with silicon nano‐pyramid array and aluminum nano‐pyramid array, respectively. The optical and electrical parameters of the DNP solar cell are presented by using the 3D finite‐difference time‐domain (FDTD) method. The short‐circuit current density (Jsc), integrated absorption (α) and photoelectric conversion efficiency (η) of the optimized DNP solar cell are 43.61 mA cm−2, 95.20% and 27.12%, respectively. Compared with the planar solar cell, the α and η of the DNP solar cell are increased by 45.31% and 15.77%, respectively. To investigate the performance of the proposed solar cell, the principle of light absorption enhancement is analyzed by spectrum and field strength distributions for the DNP structure. Furthermore, the carrier recombination and manufacturing of the DNP solar cell, and compared the structures of different arrays is studied. Further results show that the DNP structure has excellent light absorption and tolerance, which has positive significance for the development of silicon‐based thin‐film solar cells.
