specific Embodiment

[0056] Figure 1A A schematic cross-sectional view of a photovoltaic device 100 according to one embodiment is shown. The photovoltaic device 100 includes a substrate 105 , a plurality of structures 120 substantially perpendicular to the substrate 105 , and one or more grooves 130 between the structures 120 . Each recess 130 has a side wall 130a and a bottom wall 130b. Both the sidewall 130a and the bottom wall 130b have a passivation layer 131 . One top surface 120a of the structure 120 is free of the passivation layer 131 . The bottom wall 130b has a planar reflective layer 132 on the passivation layer 131 . Sidewall 130a does not have any planar reflective layer. Each structure 120 has a top portion 121 and a bottom portion 122 having different conductivity types. The term "different conductivity types" used here means that the top part 121 and the bottom part 122 cannot be two p-types or two n-types. The structure 120 can have the following four doping profiles (ie, ...

Abstract

A photovoltaic device operable to convert light to electricity, comprising a substrate, a plurality of structures essentially perpendicular to the substrate, one or more recesses between the structures, each recess having a planar mirror on a bottom wall thereof. The structures have p-n or p-i-n junctions for converting light into electricity. The planar mirrors function as an electrode and can reflect light incident thereon back to the structures to be converted into electricity.
