This research aims to identify wet-cooled CSP (Concentrated Solar Power) solar power plants connected to the existing electricity grid in Cameroon. This study uses a hybrid approach which combines an MDCM-AHP method (Multi-Criteria Analysis Method - Hierarchical Analysis Process) and a GIS (Geographic Information System). The elements studied are the climate (Direct Normal Irradiance (DNI), temperature), orography (slope and elevation) and location (proximity to the electricity network, proximity to roads and railways, proximity to homes), in order to determine the weight of these different factors and combine them to obtain the final map. The method was used to map and visualize unsuitable areas, as well as to rank suitable sites. According to the results, over 42.35 % of the country's nland is unsuitable for the construction of CSP solar plants, mainly due to excessive land use. According to the results, 0,001 % of Cameroon's land is considered "Less suitable", 44 % "Suitable", 13.46 % "Highly suitable" and 0.01 % "Most suitable".The sensitivity study includes three different situations, namely the technical scenario (high consideration of technical factors such as DNI, temperature, elevation, and slope). The economic scenario (where economic factors such as proximity to electricity grids, roads, residential areas and watercourses are taken into account) and the equal-weight scenario (where all factors are equal) clearly demonstrate that we can find very suitable areas for the installation of CSP solar plants in Cameroon, particularly in the Far North region. A detailed analysis by region shows that the theoretical potential for CSP solar energy in regions with "Less Suitable", "Suitable", "Highly Suitable" and "Most Suitable" suitability is approximately 4242.25 TWh/year, 29328.658 TWh/year, 3965.25 TWh/year and 5.794 TWh/year. The overall potential amounts to approximately 37536.159 TWh/year for all ten Canadian regions. Thanks to the model, it has been possible to identify the most suitable regions for CSP investment and offers opportunities to carry out more in-depth studies in order to choose the right site.

Developing the Cd-free electron transport layer (ETL) is a crucial subject in the field of antimony selenide (SbSe) solar cells. At present, the power conversion efficiency (PCE) of the Cd-free SbSe solar cell is still substantially lower than that of CdS-based devices. It is significant to reveal the electron transfer features in SbSe/CdS heterojunction and SbSe/Cd-free ETL heterojunction for development of a Cd-free SbSe solar cell with high PCE.

The design of electrically conductive textiles appears to be a promising approach to combat the existing challenge of deaths caused by severe cold climates around the globe. However, reports on the scalable fabrication of tolerant conductive textiles maintaining a low electrical resistance with an ability for unperturbed and prolonged performance are scarce. Here, a breathable and wrappable water-repellent conductive textile (water-repellent CT) with electrothermal and photothermal conversion abilities at low external voltage and in weak solar light is introduced, respectively.

Concentrated solar-driven CO2 reduction is a breakthrough approach to combat climate crisis. Harnessing the in-situ coupling of high photon flux density and high thermal energy flow initiates multiple energy conversion pathways, such as photothermal, photoelectric, and thermoelectric processes, thereby enhancing the efficient activation of CO2. This review systematically presents the fundamental principles of concentrated solar systems, the design and classification of solar-concentrating devices, and industrial application case studies.

Solar energy-driven steam generation is a renewable, energy-efficient technology that can alleviate the global clean water shortage through seawater desalination. However, the contradiction between resistance to salinity accretion and maintaining high water evaporation properties remains a challenging bottleneck. Herein, we have developed a biomimetic multiscale-ordered hydrogel-based solar water evaporator for efficient seawater desalination.

Herein, an eco-friendly and degradable poly(lactic acid) aerogel was prepared by combining a poly(ethylene glycol) template material with thermally induced phase separation. Due to the tailored pore size introduced by the template material, the aerogel exhibits high solar reflectance (92.0%), excellent thermal emittance (90.
