  • Publication number: 20050205126
    Abstract: A photovoltaic conversion device has a substrate 1 as a lower electrode having a first region 31 and a second region 32 adjacent to the first region, a lot of semiconductor particles 20 joined to the first region 31, an insulator 4 formed between the semiconductor particles 20 on the substrate 1 in the first region 31 and on the substrate 1 in the second region 32, a transparent conductive layer 5 as an upper electrode formed so as to cover the upper part of the semiconductor particles 20 in the first region 31 and the insulator 4 in the first region 31, and a collecting electrode formed of a finger electrode 15 arranged on the transparent conductive layer 5 in the first region 31 and a bus bar electrode 16 which is arranged in the second region 32 and connected to the finger electrode 15.

  • Patent number: 6844568
    Abstract: There is disclosed a photoelectric conversion device which is manufactured by depositing numerous crystalline semiconductor particles of one conductivity type on a substrate having an electrode of one side to join the crystalline semiconductor particles to the substrate, interposing an insulator among the crystalline semiconductor particles, forming a semiconductor layer of the opposite conductivity type over the crystalline semiconductor particles, and connecting an electrode to the semiconductor layer of the opposite conductivity type, in which the insulator comprises a mixture or reaction product of polysiloxane and polycarbosilane. The insulator interposed among the crystalline semiconductor particles is free from defects such as cracking and peeling, so that a low cost photoelectric conversion device with high reliability can be provided.

  • Patent number: 4868554
    Abstract: A raster scan type display apparatus for displaying characters having attributes. The attributes are, for example: (i) underlining, (ii) reverse video, (iii) high intensity, and (iv) blinking. The characters and attributes are stored in a refresh memmory. The display may be operated in either a field attribute mode or in a character attribute mode. In the field attribute mode, one field attribute byte in the refresh memory sets the attributes for at least one, but usually many characters which follow the field attribute byte in the refresh memory. In the character attribute mode, one character attribute byte in the refresh memory sets the attribute for only one character which precedes the character attribute in the refresh memory. In the character attribute mode, field attributes may be provided (in addition to the character attributes) for strings of characters following the field attributes.
