However, films produced by close-spaced sublimation (CSS) often suffer from defects that reduce efficiency. In this work, lithium (Li) doping was introduced to improve crystal quality, carrier concentration, and conductivity. The lithium was incorporated into the sublimation source via molten salt treatment, resulting in a uniform Li-Sb₂(S,Se)₃ thin film. The resulting ITO/CdS/Li-Sb₂(S,Se)₃/PbS/Carbon solar cell achieved a power conversion efficiency of 6.18%, a significant improvement over undoped devices. The study further investigates the optoelectronic properties, revealing that Li doping effectively reduces non-radiative recombination, improves carrier extraction, and increases the valence band maximum (VBM), optimizing energy level alignment for enhanced hole transport. Additionally, the improved surface conductivity and higher carrier concentration due to Li doping contributed to enhanced carrier transport and reduced recombination.This research demonstrates that alkali metal doping can enhance the optoelectronic properties of Sb₂(S,Se)₃ films, providing a pathway for further efficiency improvements in antimony-based thin-film solar cells.</div></div>","PeriodicalId":428,"journal":{"name":"Solar Energy","volume":"285 ","pages":"Article 113117"},"PeriodicalIF":6.0,"publicationDate":"2024-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142706399","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional desalination technologies are energy-intensive and unsuitable for rural areas. This study introduces a novel, off-grid, sustainable desalination solution utilising solar-integrated membrane distillation (MD) technology. An innovative, stand-alone prototype combining a hybrid photovoltaic/thermal (PV/T) system with direct contact MD (DCMD) has been designed and developed. This fully integrated PV/T collector efficiently supplies the thermal and electrical energy required for the MD process. The photovoltaic panel generates the necessary electrical energy, while the heat from the PV panel warms the MD system’s feed solution, enhancing overall efficiency through the solar cell cooling effect. In addition, an innovative fan-cooled radiator equipped with two DC fans with a low power consumption rating was designed and customized to be applied as MD system cooling medium within the outdoor setting. The concept development and feasibility of the system are explored in detail through a comprehensive experimental investigation employing an innovative and practical approach to design and examine the integrated hybrid solar MD unit. This unique system was designed, constructed, and tested under dynamic outdoor conditions, during the summer season in Melbourne, to assess the integration strategy and evaluate its long-term operational performance. The performance of the integrated PV/T-MD system was evaluated using two commercial hydrophobic membranes with different pore sizes under various outdoor conditions and PV/T fluid flow rates. Key performance metrics analysed include solar irradiance intensity, temperature profiles of the PV/T panel and MD module, power, current and voltage profiles of the unit components, permeate flux, specific water productivity (&lt;em&gt;SWP&lt;/em&gt;) and the thermal (&lt;em&gt;η&lt;sub&gt;thermPV/T&lt;/sub&gt;&lt;/em&gt;) and electrical (&lt;em&gt;η&lt;sub&gt;elecPV/T&lt;/sub&gt;&lt;/em&gt;) efficiencies, along with the gained output ratio (&lt;em&gt;GOR&lt;/em&gt;). Comprehensive experimental assessments in indoor and outdoor settings were undertaken to confirm the technical viability of the system. The study demonstrates the feasibility of such systems through real-world trials and addresses key challenges in energy efficiency and internal heat recovery.
