Methods and systems for photovoltaic roofing systems are provided. The system includes a back sheet including a length, L, a width, W, and a thickness, T, the back sheet including an overlap portion extending along length L having a width, WO and an active portion extending along length L having a width, WA. The system also includes a photovoltaic cell formed on a surface of the active portion, the photovoltaic cell including a photovoltaic member electrically responsive to an absorption of photons, a negative electrode coupled to a surface of the photovoltaic member, and a positive electrode coupled to the surface of the photovoltaic member, wherein the thickness T is selected such that thickness T plus a thickness of the photoelectric cell substantially match a thickness of a proximate non-photovoltaic roofing member when the photovoltaic roofing system is installed.
