Abstract: A watch incorporating an assembly (70) including a light sensor (72), including a photovoltaic cell, a negative electrode (78) and a positive electrode (79). The assembly has a first portion (52A), in which the electrodes are arranged, and a second portion (54A) which is not included in the first portion and which comprises or covers an antenna (80). The semiconductor material wafer extends into the first and second portions, and all the electrodes are arranged below the semiconductor material wafer. Preferably, this semiconductor material wafer or layer has no conductive doping in the second portion. The wafer, or layer, determines, together with additional layers provided thereon, the homogeneous colour and uniform appearance of the assembly from the side of its upper surface. Also, a dial formed by such an assembly.

Abstract: Energy-collecting display modules are disclosed. The modules include a base substrate with a plurality of sub-pixels, which are laid out in a substantially regular sub-pixel pattern. The sub-pixels are dispersed along the base substrate with sub-pixel spacing regions between individual sub-pixels. The modules also include a photovoltaic region disposed within the sub-pixel spacing regions such that the photovoltaic region minimally obscures a subpixel viewing cone region.

Abstract: A watch including a gasket (18) arranged at the periphery of the glass (14), an intermediate portion (20) laterally surrounding the analogue display and defining a radial surface forming an axial stop for the glass, a solar cell (30) extending at least mostly between the lower level of the dial and the glass and being arranged behind the intermediate portion, which is formed at least partially by a translucent or transparent material and configured to make it possible for the incident light to propagate in the intermediate portion and to subsequently reach the solar cell. The gasket is also formed at least mostly by a translucent or transparent material and it forms with the intermediate portion axially a continuous medium. In variants, the gasket is arranged axially adjacent to the intermediate portion or it is axially separated from the intermediate portion by a translucent or transparent intermediate medium.

Abstract: A display panel includes a plate-shaped decoration member including a shading part and a light transmission part formed within the shading part, as well as a plate-shaped reflection member disposed on a back side of the decoration member. The shading part and the light transmission part create a fine pattern in plan view. The reflection member is configured to reflect light. The decoration member is disposed on a front surface of the reflection member.

Abstract: Systems and methods for generating electrical current from at least one photovoltaic cell is described herein. The photovoltaic cell may be disposed over a display of an electronic device. The photovoltaic cell may comprise first and second conductive layers and a photovoltaic layer. The first conductive layer may be etched such that a width of the metal layer is less than a width of the photovoltaic layer providing visibility to the display disposed below. In some embodiments, a capacitive touch sensor is disposed between the metal layer and the absorber layer for providing interaction with a user.

Abstract: A solar cell covered with a transparent plate through a predetermined gap includes a flexible power generating layer which photoelectrically converts light incident thereon through the transparent plate, a resin layer covering a light receiving surface of the power generating layer, and an adhesion preventing layer covering the surface of the resin layer and facing the transparent plate through the gap. The adhesion preventing layer is made of an inorganic material and has a surface roughness Sz of 1 nm or more and 500 nm or less. Thus, the outermost surface of the solar cell is constituted by the adhesion preventing layer, so that no tack mark occurs even when partial contact occurs between the solar cell and the transparent plate which face each other through the gap. As a result, it is possible to prevent deterioration in appearance due to the tack mark.
