Abstract: A monolithically integrated cadmium telluride (CdTe) photovoltaic (PV) module includes a first electrically conductive layer and an insulating layer. The first electrically conductive layer is disposed below the insulating layer. The PV module further includes a back contact metal layer and a CdTe absorber layer. The back contact metal layer is disposed between the insulating layer and the CdTe absorber layer. The PV module further includes a window layer and a second electrically conductive layer. The window layer is disposed between the CdTe absorber layer and the second electrically conductive layer. At least one first trench extends through the back contact metal layer, at least one second trench extends through the absorber and window layers, and at least one third trench extends through the second electrically conductive layer. A method for monolithically integrating CdTe PV cells is also provided.
