This study compares the performance of photovoltaic cells and radiation detectors with the same device architecture but different perovskite active layer thicknesses. For perovskite solar cells, the power conversion efficiency (PCE) tends to increase with increasing active layer thickness and then decreases beyond a certain limit. On the other hand, the X-ray response characteristics of perovskite X-ray detectors tend to increase continuously with increasing active layer thickness. This means that the collections of total charges generated by photon or radiation are different, and their collection/recombination mechanisms of the charges generated in the perovskite active layer of each device are different.

Recently, CIGS solar cells have gained substantial recognition after achieving an impressive efficiency of over 23.6%. Despite this advancement and high-efficiency, the significant costs and technical complexities involved still pose major challenges to large-scale commercialization in vacuum-based processes. Solution-processed CIGS solar cells are being presented as a viable alternative to overcome these issues. This process allows for the formation of consistent thin films across large surfaces while also showing promise for reducing production costs. However, efficiency remains a key challenge and continues to be a critical factor for commercialization. The doping of new elements in CIGS absorber is an effective way to address these issues, significantly enhancing the performance of CIGS solar cells. Over the years, many elements have been incorporated into vacuum-based processes through doping, significantly contributing to high efficiency. Most notably, Uppsala University (UU) recently achieved a record efficiency of 23.6% by incorporating Sodium (Na), silver (Ag), and Rubidium (Rb). These findings imply that doping could potentially serve as a major catalyst for maximizing efficiency in solution-processed solar cells. This article reviews the latest developments in CIGS solar cells technology, summarizing the highest recorded efficiencies resulting from specific dopant incorporation strategies and combinations. Furthermore, we propose strategic approaches to improving the efficiency of solution-processed CIGS solar cells and discuss potential future research directions.</p></div>","PeriodicalId":684,"journal":{"name":"Korean Journal of Chemical Engineering","volume":"41 14","pages":"3771 - 3781"},"PeriodicalIF":2.9,"publicationDate":"2024-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142798522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To further improve the performance of VFBs, adding functional groups to the surface of carbon nanotube (CNT) to provide more active sites for promoting redox reactions of vanadium ions is one desirable way. For the purpose, adenosine (AD) and adenosine monophosphate (AMP) attached carboxylic acid functionalized CNTs (CACNT) (ADCNT and AMPCNT) are used as the catalysts. Furthermore, proper co-doping of N, O or N, P, O atoms included in AD and AMP may increase diversity of active sites. In this regard, ADCNT and AMPCNT are considered better catalysts than CACNT for increasing the reaction rate of vanadium ions because a large number of hydrophilic groups belonged to ADCNT and AMPCNT can maximize contact between catalyst and electrolyte. Quantitatively, charge transfer resistance is decreased by ~ 37.6% (ADCNT) and ~ 42.3% (AMPCNT), while peak reversibility is ~ 5.8% improved with the new catalysts. Regarding performance evaluations, voltage and energy efficiencies of VFBs using AMPCNT are best even at 250 mA cm<sup>−2</sup>, proving the above benefits of AMPCNT catalyst. Conclusively, this study confirms that larger functional groups compared to those traditionally used can act as effective catalysts, while multi-atom co-doped catalysts can be used for the performance improvement of VFBs.</p></div>","PeriodicalId":684,"journal":{"name":"Korean Journal of Chemical Engineering","volume":"41 14","pages":"3821 - 3830"},"PeriodicalIF":2.9,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142798298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
