Black silicon (b-Si) reduces drastically light reflectance in the front side of c-Si solar cells to values near zero for the whole absorbed solar spectrum. In this work, we apply 2D and 3D simulations to explore the ...

Interdigitated back contact technology is a promising candidate to be applied to thin crystalline silicon solar cells because of its simpler one-side interconnection while allowing a more flexible front surface treatment. ...

Back surface passivation is a well-known method to reduce carrier recombination and hence improves the efficiency of crystalline silicon solar cells. In this manuscript, we critically analyze the role of this process for ...

Abstract In this work, we describe a novel fabrication process of p-type interdigitated back contact (IBC) silicon solar developed by means of laser doping and laser firing techniques. We use dielectric layers both as ...

Double-sided (bifacial) heterojunction silicon solar cells have been fabricated by Hot-Wire CVD on both p- and n-type crystalline silicon substrates. In these devices, doped microcrystalline silicon layers are combined ...

En este trabajo se presenta un estudio mediante espectroscopía Raman de capas CuInSe2 sintetizadas en condiciones de defecto de Cu, en función de su composición. El interés del estudio viene motivado por el potencial de ...

In this work we investigate the effects of typical thermal treatments on c-Si surface passivation by intrinsic a-SiCx:H films. First, a forming gas anneal (FGA), (400 °C, 30 min in H2/N2) is applied resulting in an improvement ...

In this work, we study bifacial heterojunction silicon solar cells fabricated by hot-wire CVD on both p- and n-type crystalline silicon substrates. In these devices, hydrogenated microcrystalline silicon doped layers are ...
