A tandem photovoltaic cell device is disclosed including an upper and lower cell. The lower cell may comprise a glass substrate and overlying layers that may include an electrode, absorber, window layer, and a transparent conductive oxide layer. The upper cell may comprise an intermediate glass substrate and overlying layers that may include a transparent conductor, an absorber, a window layer, a second conductive oxide layer, and an upper glass material. The cells may be coupled with an optical coupling material, and edge sealing material may be disposed between the glass substrates for both the upper and lower cells. |
