A photovoltaic module comprises a transparent substrate, a plurality of photovoltaic cells formed on the back surface of the substrate, busbars each including a busbar body connected electrically to the photovoltaic cells, an electrical insulating filler covering the photovoltaic cells and the busbar bodies, a spacer, and a cover film covering the filler. Each busbar integrally includes the busbar body and an extension long enough to project from one end of the transparent substrate. The busbar extensions, which serve as output fetching lines, are bent along the spacer, and their respective output end portions are drawn out through the cover film. The output end portions are connected individually to terminals of a terminal box.

Photovoltaic module and power generation system

The dial plate according to the present invention comprises a substrate formed of a ceramic material and a colored coating layer formed on the substrate. And, the colored coating layer is characterized by having a colored layer formed of a ceramic paint containing a metal compound as a principal component. The substrate formed of a ceramic material is porous; and hence, diffuses incident light to conceal a solar battery placed on the backside from view. Since the colored layer is formed of a ceramic paint containing a metal compound as a principal component, it is easy to firmly attach it to the substrate formed of a ceramic material and it is capable of forming various colors corresponding to the types of metal compounds applied.

Dial plate for solar battery powered watch

The circuit has a power busbar, a solar generator made up of a plurality of sections that can be connected individually to the busbar via switches and a storage battery. The busbar is permanently connected to an energy-storage capacitor having a capacitance of at least 0.1 F. The busbar is powered from the battery via at least one discharge module controlled in on/off mode by a regulator which also controls the switches. The circuit is particularly suitable for use on low earth orbit (LEO) satellites.

Electrical power supply circuit having a solar generator and a battery

A dial, in particular for a timepiece, formed of at least one regenerating photoelectrochemical type solar cell including a first substrate intended to be exposed to the light and a second substrate carrying on their opposite faces electrodes between which is arranged a physico-chemical system capable of absorbing light and generating an electric voltage across the terminals of said electrodes, characterised in that said first substrate is formed of a translucent material.

Dial formed of a solar cell in particular for a timepiece

An electric device remote controller that uses little energy and solar power as source of energy. The present invention includes solar cells adopted to convert a solar energy into the electric energy, and the condenser which is connected to said solar cells to reserve converted solar energy and supply electric energy whenever needed. The present invention also includes a controller provided to controls the electric device, a data line supplies the specific data the controller, a plurality of buttons including a first terminal connected to the condenser of said electric supply system, a second terminal connected to the controller, a third terminal designated as specific datum by said data line, a fourth terminal transmit specific data transmitted from said data line, a first switching line connecting first and second terminal and a second switching line connecting third and fourth terminal. Whenever one of said remote controller buttons is pressed, then the first switching line supplies electric energy to the controller by connecting the first terminal and the second terminal and simultaneously the second switching line transmits specific data to the data line by connecting said third terminal and the fourth terminal and when the buttons are not pressed then the first switching line disconnects the first terminal and the second terminal and the second switching line disconnects the third terminal and the fourth terminal.

Remote controller for electronical appliance

A solar timepiece comprises a drive unit including a commercially available battery clock mechanism mounted to the back of a support plate for the solar cells. The clock mechanism includes hands arbors which pass through an opening in the support plate. The support plate is angularly adjustable about the axis of the hands arbors so that the longitudinal extent of the solar cells can be made to coincide with the decoratively adapted orientation of light passage areas in the dial face located directly in front of it.
