Abstract: A solar cell (10) for an electronic device, includes a substrate (100) made of a transparent material to be exposed to incident light radiation, a first electrode (110) made of a transparent, electrically conducting material, formed on one face of the substrate (100) an absorbent layer (130) extending, via an outer face (131), onto an inner face (111) of the first electrode (110), and a second electrode (120) made of an electrically conducting material and extending onto an inner face (132) of the absorbent layer (130) opposite an outer face (131) thereof, the absorbent layer (130) and the second electrode (120) being perforated so as to delimit a plurality of blind cavities (140), the bottom of each of which is formed by the inner face (111) of the first electrode (110.

Abstract: A solar cell for an electronic device including a substrate made of a transparent material to be exposed to incident light, a first electrode made of transparent electrically conductive material, formed on one face of the substrate and including an inner face opposite an outer face oriented towards the substrate, the inner face including a first portion having a roughness greater than the roughness of a second portion, an absorbent layer extending by an outer face over the first portion of the inner face of the first electrode, a second electrode made of an electrically conductive material and extending over an inner face of the absorbent layer opposite the outer face of the latter, the absorbent layer and the second electrode being perforated to delimit blind cavities, the bottom of each being formed by the second portion of the inner face of the first electrode.

Abstract: A transparent conductive oxide (TCO) layer formed using a post-TCO layer deposition process to increase roughness, aspect ratio and/or peak-to-valley heights of the surface topography relative to as-grown surface topography, and systems, apparatuses and methods thereof. A TCO layer is provided or formed with an as-grown surface topography, and processes are performed to the as-grown surface topography to modify the surface topography to increase roughness, aspect ratio, and/or peak-to-valley heights. The increase in roughness, aspect ratio, and/or peak-to-valley heights of surface topography is performed by at least one of increasing the heights of the peaks and increasing the depths of the valleys. The increase in roughness, aspect ratio, and/or peak-to-valley heights of surface topography can be to a desired or predetermined roughness and/or aspect ratio or an amount of increase in aspect ratio.

Abstract: The present invention relates to a control device (20) with redundancy for fitting to a lock having a mechanism (21) for locking an unlocking an access door, the device (20) being adapted to manage a change of state of this lock under predetermined conditions and to ensure that this state current is kept current up until the next change of state. This device (20) comprises means (30) for controlling the mechanism (21) and two units (31; 32) for providing like instructions to the control means. This device (20) is characterized in that the first unit (31) has a structure different from that of the second unit (32), while effecting common functions, and in that the control means behave functionally as an AND gate to the inputs of which are applied the instructions from the units respectively, when the device is functioning in a normal situation.
