摘要:
The present invention relates to a method for manufacturing a monolithic silicon wafer (10) comprising multiple vertical junctions (2) having an alternation of n-doped areas and p-doped areas, including at least the steps of: (i) providing a liquid bath (100) including silicon, at least one n-type doping agent and at least one p-type doping agent; (ii) proceeding to directionally solidify the silicon in a direction (I), varying the convection-diffusion parameters thereof in order to alternate the growth of n-doped silicon layers (101) and p-doped silicon layers (102); and (iii) cutting a slice (104), parallel to the direction (I), of the multi-layer structure obtained at the end of the step (ii), such as to obtain said expected wafer (10).

The invention relates to a photovoltaic module (11) comprising a plurality of photovoltaic cells (12) that are electrically connected, characterized in that it has a square shape and comprises at least two connection pads (17, 18) in each corner of the module so as to comprise at least four connectors (14, 15) on each side (21; 22; 23; 24) of the module.
摘要:
The invention relates to an electrical and/or electronic device (300) comprising: an electrical and/or electronic component (106a, 106b); two layers (102, 104) of material forming front and rear surfaces of the device, the component being encapsulated therebetween and moreover comprising at least two opposite surfaces (108a, 108b, 110a, 110b) that are placed facing both layers of material; an electrical contact element (112a, 112b, 114a, 114b) that is placed against one of the surfaces of the electrical and/or electronic component; and an element (302) that is made of a resilient material and placed between one of the two layers of material and the electrical contact element, thus forming a first layer of resilient material that covers said one of the two layers of material and a second layer (304) that is made of a resilient material having a stiffness less than that of the resilient material of the first layer, said second layer moreover being placed against the first layer of resilient material.
摘要:
Afin d'améliorer le gain d'un système d'énergie solaire photovoltaïque (2), celui-ci comprend : - une pluralité de cellules solaires photovoltaïques bifaciales (4), définissant conjointement une surface d'absorption directe (6) ainsi qu'une surface d'absorption indirecte (8), les deux surfaces étant opposées et destinées à absorber une énergie de rayonnement solaire ; - un châssis (10) de support des cellules, le châssis comprenant une structure de support (12) sur laquelle sont fixées les cellules (4). Selon l'invention, le châssis (10) comporte en outre un moyen (16) de suspension de la structure de support (12), le moyen de suspension (16) comprenant une extrémité haute raccordée à une première extrémité de la structure de support, et le moyen de suspension (16) définit une surface de réflexion (20) configurée pour réfléchir la lumière en direction de la surface d'absorption indirecte (8) définie par les cellules (4).
