In this study, we replace the traditional platinum counter electrode (CE) by composite poly(3,4-thylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS) and carbon black (CB) in the dye sensitized solar cell. The pure PEDOT:PSS CEs show the good redox potential and conductivity with appropriate open-circuit voltage (Voc) and short-circuit current density (Jsc), but the low redox ability results...
In this report, we discuss the performance change of the DSSCs by the time. It is found that the key factors which influence the device performance of DSSCs depend on the oxidation of working electrode, degradation of dye under illumination, and the solvent evaporate of the electrolyte. The oxidation of working electrode results the increase of VOC while the degradation and desorption of the dye result...
In this experiment, we use carbon black as counter electrodes to replace the conventional platinum electrodes in DSSCs. We discussed the properties and efficiency of carbon black counter electrodes by controlling the annealing temperature from 100 °C to 500 °C with various concentration of 0.5M, and 1.5M. After the proper annealing process, the conductivity and redoxing ability of the carbon black...
In this report, we composite cobalt and carbon black (CB) as the counter electrodes to replace the conventional platinum in dye sensitized solar cells (DSSCs). The basic cobalt derivatives, Co12 and Co15, showed the capability with proper JSC and VOC, but poor FF of the device. After mixing with CB, the device performances were enhanced obviously. The further improve was done by combine Co derivative...
A 90 nm 256 Kb NAND-ROM using read-1 noise elimination and read-0 sensing-margin-expanding schemes is functional at 0.29 V and 3 MHz with 100% code-coverage and 5% area overhead. This work reduces the delay-per-BL-length, energy-per-bit at VDDmin, and VDDmin-delay-product by 3000??, 4?? and 3700??, respectively, compared to previous low-voltage ROMs.
The low noise and high gain differential Low Noise Amplifier (LNA) was designed for an IEEE 802.16 Worldwide Interoperability Microwave Access (WiMAX) application. This paper presents a 3.3 GHz to 3.8 GHz CMOS LNA with differential and cascode circuits to reduce the noise figure (NF) and enhance the gain. The LNA was fabricated with Taiwan Semiconductor Manufacturing Company (TSMC) 0.18 ??m 1P6M standard...
One key factor towards the success of software and service is the standardization of service protocols/languages and the interoperability among them. While SOAP (Simple Object Access Protocol) is one such protocol for service message, its heavy performance overhead is often a big concern, as compared to the light-weighted REST (Representational State Transfer) and HTTP protocols. In this paper, we...
For sufficing the demand of the group equipment battlefield damage assessment, the development research of intellectualized emergency repair decision support system is required. In this paper, the function characteristic of the system is analyzed firstly. Then, by the further analysis, the traditional technique method is considered that has some limitations. In this way, the innovative method which...
Treatment decision-making is complex and involves many factors. A systematic decision-making and optimization technology capable of handling variations and uncertainties of patient characteristics and physician's subjectivity is currently unavailable. We recently developed a novel general-purpose fuzzy discrete event systems theory for optimal decision-making. We now apply it to develop an innovative...
