The evolution of thin active layer formation treated by TA (120 oC/10 min), SVA (in chloroform/60 s) and the combination TA+SVA was studied by atomic force microscopy (AFM) in phase contrast mode in order to determine the size domains for each post-treatment (TA, SVA or TA+SVA). The results show domains up to 500 nm wide for active layers without further post-treatment and the PCE achieved for devices fabricated with these active layers was 2.15%. On the other hand, both TA and SVA post-treatments show domains in the range of 100 to 150 nm wide as maximum, which is favorable for an efficient transport of electronic species. The PCEs for the devices were 4.96 and 4.91% for active layers treated with TA and SVA, respectively. Finally, devices with active layers treated by the combination of TA+SVA reached PCEs of 7.63 %. \u0000\u0000\u0000References\u0000[1] B. Kan et al, J. Am. Chem.

However, the issues of stability and toxicity are still remained. Our group focuses on the fundamental studies of PSCs devices, including development of a series of materials for compact layer, active layer, hole transfer layer, as well as back electrode of PSCs. In this lecture, we will introduce current progress of several types of Pb-free perovskites solar cells and remaining issues, as well as present the recent results of our group in development of Pb-free perovskites and application for solar cells. Several Pb-free perovskites have been designed and synthesized in our gourp. The electronic and optical properties of the lead-free halide double perovskites Cs2NaBX6 (B = Sb and Bi; X = Cl, Br and I) were investigated by first-principles calculation to ascertain the potential application of solar energy conversion. The designed double perovskites also were synthesized and carried out the characterization. Another work is preparation of composite active layer of bismuth triiodide (BiI3) and a layered perovskite (CH3NH3)3Bi2I9 (MBI) by a simple solution method. The nano/macrostructures of composite active layer were investigated by scanning electron microscopy (SEM) and X-ray diffraction (XRD). We found that the nanostructures and morphology of Pb-free perovskites affect significantly the performance of the solar cells fabricated. \u0000References:\u00001. H.Zhou, Y.Shi, K.Wang, Q.

From intense research in polymer-fullerene systems, some trends are becoming apparent. For example, small ~10 nm domains, high crystallinity, and low miscibility are typically measured in high-performance systems. However, the generality of these concepts for small-molecule (SM) BHJs is unclear. We present a comprehensive study of performance, charge generation and extraction dynamics, and nanomorphology in SM-fullerene BHJ devices to probe these critical structure-property relationships in this class of materials. In the systems investigated, small domains remain important for performance. However, devices composed of highly mixed domains with modest crystallinity outperform those consisting of pure/highly crystalline domains. Such a result points to an alternative ideal morphology for SM-based devices that involves a predominant mixed phase. This stems from SM aggregation in highly mixed domains that both maximize interface for charge generation and establish continuous pathways for efficient charge extraction. Such a morphological paradigm should be considered in future SM systems in pursuit of high-efficiency large-scale solar power production.","PeriodicalId":122801,"journal":{"name":"Organic, Hybrid, and Perovskite Photovoltaics XIX","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121685957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
