Porous silicon solar cell subassembly

The utility model relates to a porous silicon solar cell subassembly, this battery pack follow sensitive surface is clear glass, fluorine carbon dope layer, battery piece downwards in proper order, thermal insulation is gluey and heat dissipation backboard, link to each other through cavity glass space stop bar is sealed between around clear glass and the heat dissipation backboard clear glass is equipped with aluminum alloy frame banding with heat dissipation backboard's the cavity glass space stop bar outside all around, the battery piece is front electrode, surperficial porous silicon layer, N type silicon layer, P type silicon layer, extend silicon layer, porous silicon reflection stratum, silica -based substrate and aluminium back electrode layer downwards from the sensitive surface in proper order. The utility model discloses a porous silicon because the refractive index ratio silicon metal of porous silicon is little, can effectively reduce the reflection loss of sunlight radiation as battery pack's vi
