The increased interest, however, must be accompanied by thorough testing under a broad range of space-related sources of degradation and investigation of their effects on the layer stack. In this work, the resilience against atmospheric neutron radiation (<800 MeV) of flexible devices is studied, using two different hole transporting materials: a commercial PTAA and a PTAA-based in-house synthesized polymer. After 5 109 particles/cm2 irradiation, 380 times higher than the yearly fast neutron fluence in low Earth orbit, the devices show good stability, with efficiency losses below 20%. Further investigation by light intensity-dependent JV scans, hyperspectral photoluminescence microscopy, X-ray diffraction, X-ray reflectivity, and atomic force microscopy reveals that the neutron radiation mainly affects the perovskite/hole transport layer interface, to a different extent depending on the material. This work confirms that accelerated stress testing is an important tool to determine the feasibility of this technology for space applications and provides insights on the damages caused by atmospheric neutrons which will help inform future decisions for the fabrication of space-resilient flexible perovskite solar cells.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"9 14","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/solr.202500126","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144687940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We deposit trimethyl-silyl Si(CH3)3 groups using hexamethyldisilazane (HMDS) as the precursor over passivating dielectric layers and their stacks (SiO2, SiNx, SiO2/SiNx) and interrupt the HMDS attachment chemistry shortly before a full monolayer is formed on its surface. Subsequent etching in dilute HF produces pinholes through the dielectric layers due to the higher etch resistance of the SAM to HF etching. The pinhole areal density (104–108/cm2) and size (10–1000 nm) can be tuned both by duration of HMDS attachment and HF etch time. Pinholes were characterized by atomic force microscopy, tetramethylammonium hydroxide (TMAH) selective etch, and Ag decoration by electroless plating. Polysilicon (poly-Si) passivated contacts enabled by pinholes were formed by subsequent deposition of doped amorphous silicon (a-Si:H) followed by thermal crystallization and dopant drive-in. At optimal areal pinhole density ≈107/cm2, contacts exhibit both passivation and carrier transport via pinholes as evidenced by electron beam induced current, transmission line measurements, and carrier lifetime measurements. Solar cells based with these pinhole contacts show Voc = 723 mV and FF = 80.3%.

Upon further annealing over the temperature range of 200–350°C in the dark, depending on the type of doping, the surface passivation either shows further degradation followed by recovery, or direct recovery to the initial iVoc. Annealing at higher temperatures and/or higher illumination intensities accelerates the kinetics for both degradation and recovery processes. We show that the degradation and recovery processes are thermally activated and proceed identically in subsequent firing and annealing steps showing their cyclic nature. We present a series reaction model to explain the kinetics of degradation and recovery processes for n+ and intrinsic poly-Si/SiOx contacts. By fitting the model's rate expressions to the data, the determined effective activation energy barriers for degradation and recovery for n+ poly-Si/SiOx contacts in the dark are 1.24 and 1.51 eV, which are lowered under 7.5 Suns illumination to 0.76 and 1.15 eV, respectively.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"9 14","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/solr.202500133","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144687970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study explores the integration of CsPbBr3 quantum dots (QDs) with MAPbI3-base perovskites as a strategy to convert ultraviolet light into visible light, thus enhancing both power conversion efficiency (PCE) and operational stability. Two types of QDs—one synthesized at room temperature with short-chain ligands, the other commercially produced via hot injection with long-chain ligands—are compared to assess the influence of synthesis route and surface chemistry on device performance. Heterojunction solar cells are fabricated by drop-casting in ambient conditions, using a combination of QDs, MAPbI3 and the AVAI additive. Various integration methods (blending into the perovskite matrix, sequential deposition, and surface application) are investigated. Devices incorporating QDs show a PCE improvement of up to 11.8%, reaching 10.4% compared to 9.3% for the reference. Thanks to advanced characterization techniques, these results offer valuable insights into how the properties of quantum dots influence charge generation mechanisms, paving the way for more robust and scalable carbon-based perovskite solar cell technologies.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"9 14","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144687969","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While iodide-based RPPs are well-studied, the crystallization of mixed-halide RPPs remains less explored. Understanding the factors affecting their formation and crystallization are vital for optimizing morphology, phase purity, and orientation, which directly impact device performance. Here, we investigate the crystallization and properties of mixed-halide RPPs (PEA)2FAn−1Pbn(Br1/3I2/3)3n + 1 (PEA = C6H5(CH2)2NH3+ and FA = CH(NH2)2+) (n = 1, 5, 10) using DMSO ((CH3)2SO) or NMP (OC4H6NCH3) as cosolvents and MACl (MA = CH3NH3+) as an additive. For the first time, the presence of planar defects in RPPs is directly observed by in situ grazing-incidence wide-angle X-ray scattering (GIWAXS) and confirmed through the simulation of the patterns that matched the experimental. GIWAXS data also reveals that DMSO promotes higher crystallinity and vertical orientation, while MACl enhances crystal quality but increases halide segregation, shown here by nano X-ray fluorescence (nano-XRF) experiments. For low-n RPPs, orientation is crucial for solar cell efficiency, but its impact decreases with increasing n. Our findings provide insights into optimizing mixed-halide RPPs, guiding strategies to improve crystallization, phase control, and orientation for better performance not only in solar cells but also in other potential optoelectronic devices.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"9 14","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/solr.202500404","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144688201","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

DSSCs using [Co(bpy)3]2+/3+ redox mediators often face stability challenges due to light–induced interaction with tert-butylpyridine (TBP), an electrolyte additive. This leads to the loss of electrochemically active mediators and degradation of the photovoltaic performance. However, the monolithic DSSCs in this work demonstrate unprecedented stability under continuous light soaking for over 1000 h. The stability is attributed to the device architecture and the carbon CE, which mitigate critical degradation mechanisms. Additionally, its adsorption capacity and opacity reduce the amount of free TBP in the electrolyte, thereby suppressing harmful photoinduced [Co(bpy)3]³+-TBP complexation and water-induced redox reactions. Despite high TBP concentrations (1.2 M), which typically accelerate degradation in conventional DSSCs, the monolithic devices maintained their performance due to electrolyte retention and reduced ion diffusion within the porous carbon layer. This study highlights the critical role of architecture in stabilizing cobalt-mediated DSSCs, paving the way for robust, long-term energy conversion applications.","PeriodicalId":230,"journal":{"name":"Solar RRL","volume":"9 14","pages":""},"PeriodicalIF":6.0,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144688202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
