897,528. Semi-conductor devices. GENERAL ANILINE & FILM CORPORATION. March 9, 1960 [March 12, 1959], No. 8330/60. Class 37. [Also in Group XL (a)] A photo-voltaic cell consists of a layer of a light-sensitive electrophotographic sensitizing dye having on each side an electrically-conducting support. Fig. 1 shows two glass plates 1, 1a, each having a transparent conductive coating 2, 2a. A sensitizing dye such as rose bengal dissolved in methanol was poured on to the conducting surface. After the solvent had evaporated the two layers 3, 3a were pressed firmly together as shown. Connections 5, 6 were made to the overhanging portions. An opaque backing may be used on one side (Fig. 3, not shown), or the glass plates may be brought together while still moist with solvent. An arrangement is described (Fig. 4, not shown), in which an A.C. supply causes an electroluminescent panel to luminesce. The luminescent illuminating a cell of the type described above which provides a D.C. output. Suitable dyes are the phthalein dyes, i.e. eosin, rose bengal, fluorescein, erythrosin and other fluorescein types and tryphenylmethane types such as crystal violet and malachite green.
