Summary: A 90-nm-thick TiO2 grid was fabricated using photolithography, sputtering, and lift-off process. A nanoporous film was deposited on the TiO2 grid, which induced a protrusive structure. Experimental results showed that introducing the TiO2 grid into a dye-sensitized solar cell increased its power conversion efficiency by 25%. This improvement can be attributed to the large surface area and directional electron transport channels of the protrusive structure.

Summary: The carbon quantum dot (C-dot) acts as a photosensitizer and dye-adsorber. Adding C-dot to TiO2/NiO(10 wt%) nanocomposites significantly enhances the power conversion efficiency (PCE) of dye-photosensitized solar cells (DSSCs) up to 2.88 times. However, in TiO2/CuO/C-dot nanocomposites, the addition of C-dot leads to a decrease in PCE.

Summary: Co-sensitization using natural and synthetic dyes from Hibiscus sabdariffa and Rhodamine, respectively, is investigated for enhancing the performance of DSSCs. The UV-Vis absorption spectra demonstrate the overlapping absorption of the mixed dye, indicating cumulative light harvesting. DSSCs are characterized using UV-Vis Spectroscopy, SEM, FTIR, XRD, EDS, and EIS. The co-sensitized dye solar cell shows the highest Jsc of 4.02mA and power conversion efficiency of 1.23%, attributed to light harvesting and effective dye loading.

Summary: Research has been conducted for over two decades on Dye-Sensitized Solar Cells (DSSCs) due to their low cost, easy preparation methodology, less toxicity, and ease of production. This study focused on the performance of DSSCs with different particle sizes, finding that TiO2 nanoparticles with smaller particle size distribution had lower conversion efficiency. Additionally, it was observed that trimodal distribution with larger size can absorb different wavelengths due to the broad distribution of the particle size.

Summary: Indium doping of cadmium sulfide (CdS) by chemical bath deposition (CBD) is an efficient strategy to enhance the efficiency of CIGSSe. However, the low solubility of In2S3 limits the In doping contents and band energy-level regulation for CdS using traditional CBD process. In this study, a novel CBD method is used to prepare indium-doped CdS (In:CdS) buffer by slowly adding the indium source in the growing solution. This reduces the In ion concentration during real-time deposition and leads to the formation of compact and uniform In:CdS with higher indium doping content. In:CdS improves the heterojunction quality of CIGSSe by elevating the CdS conduction band edge, achieving a more favorable band alignment and enhancing carrier transport efficiency while reducing interface defect density. The solution-processed CIGSSe device with In:CdS as a buffer exhibits a high efficiency of 16.4%, characterized by a high V-OC of 670 mV and an FF of 75.3%.

Summary: The main bottleneck in the development of kesterite Cu2ZnSn(S,Se)(4) (CZTSSe) solar cells is their very low V-OC due to severe carrier recombination. By implementing Cd gradient doping near the front interface during selenization, interface recombination can be significantly reduced, leading to an improved V-OC and higher photovoltaic conversion efficiency.

Summary: This study provides evidence for magmatism associated with intracontinental extension by systematically studying the Late Jurassic mafic to ultramafic rocks in the Beidashan Taolai region. The results show that the Taolai hornblende gabbro, formed in the Late Jurassic, has geochemical properties consistent with high alumina mafic rocks. This suggests that they might have been produced by fractional crystallization of primary magma generated by decompressional partial melting of the asthenosphere mantle.

Summary: Solar cells based on emerging kesterite Cu2ZnSn(S,Se)(4) (CZTSSe) materials have shown high power conversion efficiency (PCE) of 13.6% and have great potential in next-generation photovoltaic technologies. CZTSSe devices fabricated by a low-cost solution method have performed well, although not reaching as high efficiency as vacuum-deposited CIGS devices. The characteristics of the solvent used in the solution method play a crucial role in determining the properties of CZTSSe thin films.

Summary: In this study, a MoO3-modified layer was introduced on the Mo electrode by spin-coating Na2S aqueous solution, which improved the power conversion efficiency of CZTSSe solar cells. The MoO3 layer inhibited the reaction between Mo and CZTSSe and improved the quality of the back interface. The Na2S layer enhanced the crystallinity of the absorber and the quality of the p-n heterojunction. Optimizing the Na2S layer increased the average PCE of the CZTSSe solar cell from 10.22% to 12.48%.
