Abstract: Disclosed are aluminum paste compositions for silicon photovoltaic cells, that display reduced blistering, reduced yellow discoloration, reduced bowing, increased (or maintained) open-circuit voltage (Voc), and possess an increased firing window, through modification of the organic binder and/or addition of pigments. The present invention relates to the improvement of cosmetic and physical properties of silicon photovoltaic cells. The present invention also relates to the use of pigment to reduce the discoloration of fired aluminum pastes on silicon wafers for use as photovoltaic cells.
