In this paper, we reported the preparation of fully-solution processed n-i-p type PSCs with spray-coated silver nanowires (AgNWs) top electrode. Experiment results demonstrated that low power conversion efficiency (PCE) of 16.00% with a low fill factor of 67.41% was obtained for the reference cell, when the AgNWs is directly coated on the 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenylamine)-9,9′-spirobifluorene (Spiro-OMeTAD) layer. This result indicates a charge extraction barrier at the Spiro-OMeTAD/AgNWs interface, which could be attributed to the poor compatibility between Spiro-OMeTAD and AgNWs layers. By inserting a thin layer of poly(3,4-ethylenedioxythiophene):perfluorinated sulfonic acid ionomers (PEDOT:F), a modified PEDOT with lower surface energy, the interface connection between Spiro-OMeTAD/PEDOT:F and AgNWs was improved, leading to an enhanced PCE of up to 19.11%. In addition, the PEDOT:F-based cells retained 64% of the initial PCE after operating at the maximum power point for 1800 hours, whereas the reference cells retained only 30% of the initial PCE.

In this paper, we show that inkjet-printed devices can have both high field-effect mobility and on-off current ratio by utilizing coffee ring induced thickness variation in the channel. The coffee ring effect occurs naturally in printed patterns with most solvents and substrates, and it pushes dissolved particles to the edges of printed features. Thickness variation and coffee ring effect are usually avoided in the channel of solution processed TFTs by implementing additional expensive steps in the fabrication process. Instead, here, we control these variations and utilize them to create inkjet-printed CNT channels with printing induced thickness variation that improves transistor properties. Printing properties such as printing speed, and number of layers are studied to manipulate capillary flow and form thicker line edges, which ultimately enhance current transport in the CNT network. A two-pass printing pattern with separate lines improves the field-effect mobility five times compared to a pattern with connected lines that has no defined edges. The field-effect mobility increases from 1.1 to 5.7 cm2/V.s at a drain voltage of -2 V.","PeriodicalId":51335,"journal":{"name":"Flexible and Printed Electronics","volume":"40 23","pages":""},"PeriodicalIF":3.1,"publicationDate":"2024-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139442497","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}

The shape and morphology of the printed traces depend on the printing system, a combination of ink and substrate properties, and the printed technology used for fabrication. This paper investigates the significance of printing parameters like roughness, height, width, and profile shape on the RF performance of screen-printed traces statistically. This paper also derives a model based on actual profile shape and roughness measurements from incorporating these effects into the simulations. From the statistical study, we found that the role of surface roughness becomes more significant as the frequency increases. Thus, modeling surface roughness in flexible hybrid electronics simulations is fundamental for accurate results. Different simulated profile shapes also showed their effect on the RF performance, when combined with roughness, showed better correlation with experimental data. Our proposed model combines the modified Morgan and Hammerstad equation with the compound conductor model. Our proposed model uniquely integrates the modified Morgan and Hammerstad equation with the compound conductor model, leveraging a comprehensive approach focused on the quality and uniformity of printed electronics trace. This integration is aimed at constructing a model that is firmly grounded in actual roughness data, resulting in a solution that is both straightforward to implement and exceptionally accurate in its outcomes. The model agreed well with experimental measurement data over 7 GHz–40 GHz with a root-mean-square error average of 5.7%.","PeriodicalId":51335,"journal":{"name":"Flexible and Printed Electronics","volume":"5 1","pages":""},"PeriodicalIF":3.1,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139056607","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}

The device comprises electrodes made from a commercial Ag ink, a heating area using a commercial carbon ink, and a thermochromic layer employing a commercial ink with a standard activation temperature of 31°C. We designed a specialized experimental setup to evaluate the performance of the optical flow sensor under static and dynamic conditions. To analyze the device's thermal response and performance across various flow conditions, we utilized a combination of electrical measurements and IR-optical imaging techniques. The all-printed device operates on the basis of a thermodynamic cycle frequency, which activates the thermochromic ink, causing it to blink at a frequency related to the flow passing over the sensor. The results of our preliminary testing are highly promising, as the sensor successfully demonstrated a clear relationship between flow and optical duty cycle.

Decreasing the drop volume, increasing the drop spacing, and increasing the ink-substrate contact angle are all approaches by which the line width can be lowered, however these approaches are limited by the nozzle geometry, ink coalescence and bead instabilities, and contact angle hysteresis, respectively. Here we demonstrate a novel approach for stable inkjet printing of very narrow lines on ink-substrate combinations with a high contact angle, utilizing the de-wetting of the ink due to the decreased contact angle hysteresis. After printing and drying an initial layer of disconnected seed drops of silver nanoparticle ink, we print an additional layer of bridging drops of the same ink in between the dried seed drops. The bridging drops expand to touch the dried seed drops and then retract into a line, due to the pinning of the wet ink on the dried seed ink but not on the substrate, forming a continuous silver trace. The trace width is decreased from 60 <italic toggle=\"yes\">μ</italic>m with a traditional printing approach down to 12.6 <italic toggle=\"yes\">μ</italic>m with this seed-bridge approach. The electrical conductivity of the silver trace is similar to that of a conventionally printed trace.
