Abstract:
Cadmium telluride (CdTe), a metallic dichalcogenide material, was utilized as an absorber layer for thin film–based solar cells with appropriate configurations and the SCAPS–1D structures program was used to evaluate the results. In both known and developing thin film photovoltaic systems, a CdS thin–film buffer layer is frequently employed as a traditional n–type heterojunction partner. In this study, numerical simulation was used to determine a suitable non–toxic material for the buffer layer that can be used instead of CdS, among various types of buffer layers (ZnSe, ZnO, ZnS and In2S3) and

Abstract:
Conventional single-component quantum dots (QDs) suffer from low recombination rates of photogenerated electrons and holes, which hinders their ability to meet the requirements for LED and laser applications. Therefore, it is urgent to design multicomponent heterojunction nanocrystals with these properties. Herein, we used CdSe quantum dot nanocrystals as a typical model, which were synthesized by means of a colloidal chemistry method at high temperatures. Then, CdS with a wide band gap was used to encapsulate the CdSe QDs, forming a CdSe@CdS core@shell heterojunction. Finally, the CdSe@CdS co

Time- and spectrally resolved measurement of photoluminescence InAsP nanoinsertions in the near infrared region at temperatures of 80 K and 293 K were made.

Abstract:
Studies show that during thermal processing, major changes occur in p-CdS/p-CdTe/ZnTe/ZnCdS heterojunctions. The nature of the change in electrical and photoelectric properties of heterojunctions depending on thermal processing conditions shows that the volume charge layer expands due to the presence of acceptor levels near the surface of the Zn1-xCdxS layer (Fig. 1). Therefore, the capacity of p-n heterojunctions decreases. The increase in photoresponse across all spectra indicates that the compensation of donor-type natural defects with acceptor levels results in the formation of a high-resi

The sputtering is conducted in a reactive mode using metal or alloyed metal targets fitted to a custom-made linear cathode. It is notable that the CdS buffer layer conventionally employed in CdTe solar cells is entirely replaced by the ZMO window layer. The use of ZMO is found to eliminate the blue loss a

Abstract:
Abstract Thin layer ZnTe-CdSe heterojunctions were produced by vapor phase epitaxial growth of ZnTe and CdSe layers on mica and single-crystal ZnSe substrates. These heterojunctions photosensitivity covers the wavelength region of 0.56–0.85 μm. The shape of photosensitivity spectral dependence of ZnTe-CdSe heterojunction depends on the components thickness and their doping level. Thin layer ZnTe-CdSe epitaxial heterojunction parameters under illumination of 80 mW/cm2 (AM1.5) are: FF=0.53, Uoc=0.72V, Isc=14.8 mA/cm2, efficiency η=7.1%.
