摘要：
The present invention relates to photovoltaic devices which comprise: a semiconducting material able to ensure a photovoltaic effect when it is subject to electromagnetic radiation; a anti-reflective layer, transparent towards said electromagnetic radiation ensuring the photovoltaic effect, this anti-reflective layer containing, in the dispersed state, objects with dimensions of less than 5 microns, preferably less than 2 microns, said objects comprising at least two areas consisting of two different substrates, transparent towards said electromagnetic radiation and having distinct refraction indices, i.e.: a core having a first refractive index nC; and a layer surrounding the core, a so-called crust, having a second refractive index nE, distinct from the refractive index nC of the core, the ratio of the dimensions of the core to the dimensions of the core/crust assembly being comprised 1:1.5 and 1:5.
摘要（中）：
本发明涉及光伏器件，其包括：半导体材料，当其经受电磁辐射时能够确保光伏效应; 所述抗反射层对于确保光伏效应的所述电磁辐射是透明的，该抗反射层在分散状态下包含尺寸小于5微米，优选小于2微米的物体，所述物体包括至少两个区域 由两个不同的衬底组成，对所述电磁辐射透明并具有不同的折射指数，即具有第一折射率nC的芯; 以及围绕芯的层，所谓的外壳，具有与芯的折射率nC不同的第二折射率nE，芯/尺寸与芯/外壳组合的尺寸之比为1 ：1.5和1：5。
