Claim Text:
1. A photovoltaic module comprising: a sintered silicon support wherein the sintered silicon support and the layer of non-porous silicon together comprise several integrated photovoltaic cells and a layer on non-porous silicon on said sintered silicon support; the sintered silicon support comprising porosity channels, wherein only some of said porosity cannels are oxidized, said oxidized porosity channels forming oxidized portions of said sintered silicon support that insulate said photovoltaic cells from one another; and at least one trench defined through said layer of non-porous silicon, extending to an upper surface of said sintered silicon support, wherein the oxidized porosity channels in the sintered silicon support are located directly under the at least one trench of the non-porous silicon layer.
