  • Publication number: 20120235268
    Abstract: A photoelectric conversion module comprises: a substrate having a first surface on which a light is incident and a second surface located at the opposite side of the first surface; a photoelectric conversion element provided on the second surface of the substrate; a light-transmitting member provided on the photoelectric conversion element; and a reflecting member provided on the light-transmitting member and configured to reflect a light having transmitted through the light-transmitting member. The reflecting member comprises an inclined light reflection surface that allows a light reflected from the reflecting member to be totally reflected at the first surface of the substrate.

  • Publication number: 20060223831
    Abstract: The 1-(2-methoxyethyl)-2-methyl-4,9-dioxo-3-(pyrazin-2-ylmethyl)-4,9-dihydro-1H-naphtho[2,3-d]imidazol-3-ium bromide of the invention and its crystals, particularly ?- and ?- form Crystals, have no hygroscopic property, have excellent stability and therefore are useful as production materials of medicines. Particularly, the ?- form Crystal is most stable and markedly useful as a bulk for medicines.

  • Patent number: 7001831
    Abstract: A non-Si non-C-based gas is heated by a thermal catalysis body provided in a gas introduction channel, and the heated non-Si non-C-based gas and a material-based gas comprising Si and/or C are separately introduced into a film deposition space through a showerhead having a plurality of gas effusion ports, and in the film deposition space, a plasma space is formed by a nonplanar electrode connected to a radio frequency power supply, thereby forming a film on a substrate. Formation of high-quality Si-based films and C-based films can thus be accomplished at high deposition rate over large area with uniform film thickness and homogeneous quality. Also, highly efficient devices including photoelectric conversion devices represented by solar cells can be manufactured at low-cost by the use of such films.

  • 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: 6868786
    Abstract: A patterning method for micro-contact printing involves the steps of: applying a resin on a master having projected patterns, hardening the resin and thereafter removing the hardened resin from the master to make a stamp of the resin; applying a molecular ink including hydrophobic molecules dispersed in a solvent on the stamp; forming micro-contact printed patterns of the hydrophobic molecular layer on a substrate by means of the stamp on which the molecular ink is applied; dipping the substrate with micro-contact printed patterns in a hydrophilic molecule solution dispersed in a solvent to give chemical modification to the areas of the surface of the substrate around the micro-contact printed patterns, the solution including hydrophilic molecules having a chain length shorter than the chain length of hydrophobic molecules included in the molecular ink is used as the hydrophilic molecule solution.
