Summary: A novel and green ionic liquid-assisted ink is developed for the fabrication of highly efficient CIGSSe solar cells by inkjet printing. Compared to the conventional vacuum-based deposition and spin-coating solution methods, inkjet printing technology can remarkably improve the material utilization of copper indium gallium sulfur selenium (CIGS) and achieve a flat and continuous deposition of CIGS thin film. The inkjet-printed CIGSSe solar cells show an encouraging power conversion efficiency of 15.22%.

Summary: Sb2S3-ySey thin films were prepared using a hydrothermal growth solution and solar cells with FTO/CdS/Sb2S3-ySey/spiro-OMeTAD/Au architecture were fabricated. The position of CdS/FTO substrate and the volume of growth solution strongly influenced the properties of Sb2S3-ySey thin films and the photovoltaic performance of solar cells. The introduction of P3HT and TMT-TTF into spiro-OMeTAD increased the power conversion efficiency of Sb2S3-ySey solar cells.

Summary: This study proposes a two-terminal monolithic Sb2S3/Si thin film tandem solar cell structure and investigates it through TCAD simulation. By optimizing the structure of the top sub-cell and the bandgap of the bottom thin-film silicon cell, a conversion efficiency of 10.10% is achieved. Further optimization of various parameters improves the efficiency of the tandem cell to 19.51%.

Summary: Accurate efficiency prediction, improved reliability, and extended lifetime of solar modules are key factors driving investment and research in photovoltaic (PV) systems. Incorporating data from localized monitoring of solar modules enhances performance and improves modeling. This study combines flexible thin-film transistor (TFT) interface circuits with distributed temperature sensors integrated into solar cell lamination to enable in-module within-cell PV monitoring. A TFT multiplexer selects sensors and is controlled via a serial peripheral interface (SPI) to reduce IO connections, while a low offset unity-gain TFT buffer ensures precise signal transfer. The in-cell sensors, along with the TFT read-out circuitry, demonstrate accurate outdoor temperature monitoring comparable to silicon integrated circuits.

Summary: The structural heterostructured CdS buffer layer can promote the vertical growth of Sb2Se3 nanoribbons, resulting in improved device efficiency of the solar cells. The improved buffer/absorber interface and reduced interface defects and recombination loss contribute to the efficiency enhancement. This new strategy provides a way to regulate the crystal growth of Sb2Se3 nanoribbons and further improve the efficiency of low-dimensional chalcogenide thin film solar cells.

Summary: In this study, antimony sulfoselenide (Sb-2(S, Se)(3)) thin-film solar cells were fabricated using a hydrothermal method and post-deposition annealing at different temperatures. The impact of annealing temperature on the morphological, structural, optoelectronic, and defect properties of the hydrothermally grown Sb-2(S, Se)(3) films was investigated. The results showed that an appropriate annealing temperature led to high-quality Sb-2(S, Se)(3) films with desirable characteristics and reduced defect density, resulting in improved power conversion efficiency of the Sb-2(S, Se)(3) solar cells.

Summary: This study investigates the absorption efficiency of a thin-film solar cell composed of metallic nanowires and semiconductors, with results showing over 90% absorption using a rectangular-nanowire system and semi-circular nanowire cross-section in specific wavelength ranges. The high absorption in the visible region could potentially benefit the design of plasmonic solar cells.

Summary: We report the processing of large-grained chalcopyrite-CuIn(S,Se)2 (ch-CISSe) films using spray deposition of wurtzite-CuInS2 (wz-CIS) nanoparticle ink and subsequent selenization. The transformation from wurtzite to chalcopyrite phase and grain growth were studied at different selenization temperatures. It was found that at the suitable selenization temperature and time, the film can completely transform into chalcopyrite phase and the grains can grow.
