    Notes: 13C and 1H NMR spectra of two series of mesogenic compounds dissolved in CDCl3 were studied. The compounds are 4-n-alkyl-4′-cyanobiphenyls and 4-n-alkyloxy-4′-cyanobiphenyls, with the alkyl group ranging from pentyl to octyl. 13C and 1H chemical shifts and 13C-1H scalar coupling constants are tabulated.

    Further study of inversion layer MOS solar cells (1987)
    In:  CASI
    Details
    Publication Date: 2013-08-31
    Description: A group of inversion layer MOS solar cells has been fabricated. The highest value of open-circuit voltage obtained for the cells is 0.568V. One of the cells has produced a short-circuit current of 79.6 mA and an open-circuit voltage of 0.54V. It is estimated that the actual area AMO efficiency of this cell is 6.6 percent with an assumed value of 0.75 for its fill factor. Efforts made for fabricating an IL/MOS cell with reasonable efficiencies are reported. Future work for 4 sq cm IL cells and 25 sq cm IL cells is discussed.

    Further study of inversion layer MIS solar cells (1992)
    In:  CASI
    Details
    Publication Date: 2019-06-28
    Description: Many inversion layer metal-insulator-semiconductor (IL/MIS) solar cells have been fabricated. As of today, the best cell fabricated by us has a 9.138 percent AMO efficiency, with FF = 0.641, V(sub OC) = 0.557 V, and I(sub SC) = 26.9 micro A. Efforts made for fabricating an IL/MOS solar cell with reasonable efficiencies are reported. The more accurate control of the thickness of the thin layer of oxide between aluminum and silicon of the MIS contacts has been achieved by using two different process methods. Comparison of these two different thin oxide processings is reported. The effects of annealing time of the sample are discussed. The range of the resistivity of the substrates used in the IL cell fabrication is experimentally estimated. Theoretical study of the MIS contacts under dark conditions is addressed.

    Computer modeling of inversion layer MOS solar cells and arrays (1991)
    In:  CASI
    Details
    Publication Date: 2019-07-13
    Description: A two dimensional numerical model of the inversion layer metal insulator semiconductor (IL/MIS) solar cell is proposed by using the finite element method. The two-dimensional current flow in the device is taken into account in this model. The electrostatic potential distribution, the electron concentration distribution, and the hole concentration distribution for different terminal voltages are simulated. The results of simple calculation are presented. The existing problems for this model are addressed. Future work is proposed. The MIS structures are studied and some of the results are reported.
