  • a complete process for production of flexible large area polymer solar cells entirely using screen printing first Public Demonstration
    Solar Energy Materials and Solar Cells, 2009
    Co-Authors: Frederik C Krebs, Mikkel Jorgensen, Kion Norrman, Ole Hagemann, Jan Alstrup, Torben Damgaard Nielsen, Jan Fyenbo, Kaj Larsen, Jette Kristensen
    Abstract:

    Abstract A complete polymer solar cell module prepared in the ambient atmosphere under industrial conditions is presented. The versatility of the polymer solar cell technology is demonstrated through the use of abstract forms for the active area, a flexible substrate, processing entirely from solution, complete processing in air using commonly available screen printing, and finally, simple mechanical encapsulation using a flexible packaging material and electrical contacting post-production using crimped contacts. We detail the production of more than 2000 modules in one production run and show that the production technique is scalable and well suited for direct transfer to the printing industry employing existing production equipment. The production speed and cost analysis for the individual modules from this batch is discussed and a forecast for the high volume cost based on this method is given. Further, the points where significant cost reductions can be achieved are identified. The use of the solar cell as the power supply for a small radio and other small electronic circuits is demonstrated. Lastly, the operational stability under ambient conditions in the dark and under illumination is discussed.

  • john logie baird and the secret in the box the undiscovered story behind the world s first Public Demonstration of television
    Proceedings of the IEEE, 2020
    Co-Authors: Brandon D. Inglis, Gary Douglas Couples
    Abstract:

    On January 26, 1926 (see Fig. 1 ), John Logie Baird gave a Demonstration at his laboratory in 22 Frith Street, London, of the live transmission of moving images, obtained in reflected light with tonal graduation, to members of the Royal Institution. This event is generally accepted as the first Public Demonstration of true television [1] , [2, pp. 88–107] , [3, pp. 65–84] . Ten months earlier, on March 25, 1925, Baird had demonstrated the televising of moving silhouette images, at Selfridge’s department store, on Oxford Street in London [2, p. 57] , [3, p. 75] . What had changed in those ten months to enable Baird to televise a sufficient tonal range of moving human faces? This article describes the set of events which led up to Baird’s accomplishment and answers the question concerning the technology employed.

  • ICCE-Berlin - An IEEE 802.15.4g SUN FSK RF CMOS transceiver for Smart Grid and CEs
    2013 IEEE Third International Conference on Consumer Electronics ¿ Berlin (ICCE-Berlin), 2013
    Co-Authors: Seung Sik Lee, Sang Sung Choi, Jae-young Kim, Kang-yoon Lee
    Abstract:

    The proposed IEEE 802.15.4g SUN FSK (Frequency Shift Keying) RF CMOS transceiver, for the advanced ZigBee, can be adapted to Smart Grid application, but also CEs(Consumer Electronics) Application. With proposed SUN RF transceiver, wireless connectivity among CEs devices and electric meters not only can make lives more comfortable but also save electronic energy. The proposed RF transceiver consists of a digital PLL (Phase Locked Loop), a Driver amplifier, a Modulator, a LNA (Low Noise Amplifier), Complex Band Pass Filter, 3-stage VGA (Variable Gain Amplifier), and Demodulator. The proposed RF transceiver is implemented in a 0.18-μm CMOS technology as a part of SoC and consumes 18~34-mA in TX and 28-mA in RX mode from a 1.8-V supply voltage. In addition, with a fabricated RF transceiver chip, we have succeeded a Public Demonstration.

  • an ieee 802 15 4g sun ofdm based rf cmos transceiver for smart grid and ces
    International Conference on Consumer Electronics, 2013
    Co-Authors: Seung Sik Lee, Sang Sung Choi, Jae-young Kim, Byounghak Kim, Changwan Kim
    Abstract:

    The proposed SUN OFDM-based RF CMOS transceiver, with replacement of ZigBee, can be used as not only an energy saving intelligent green home, which is related to Smart Grid, but also an universal remote controller, a Building Automation, and so on. With our proposed SUN OFDM RF transceiver, wireless connectivity among CEs (Consumer Electronics) devices and electric meters can save electronic energy and make lives more comfortable. The proposed RF transceiver consists of a RF front-end, a TX BBA (Base Band Analog), a RX BBA, and a PLL. Re-using of a LC resonator in the RF front-end can reduce the chip size of RF transceiver, DC power consumption, and the cost. The proposed RF transceiver is implemented in a 0.18-μm CMOS technology and consumes 37-mA in TX and 38-mA in RX mode from a 1.8-V supply voltage. In addition, with a fabricated RF transceiver chip, we have succeeded a Public Demonstration.
