1. A method for manufacturing a photovoltaic device comprising:
fabricating a first photovoltaic device portion with a first perovskite material layer having a first face;
fabricating a second photovoltaic device portion with a second perovskite material layer having a second face, wherein the second photovoltaic device portion has a third perovskite material layer, and wherein the first perovskite material layer and the second perovskite material layer have a different chemical formula or composition;
placing a glass frit paste, ink, solution, or powder around a perimeter of the first photovoltaic device portion;
arranging the first photovoltaic device portion and the second photovoltaic device portion such that the first face is in contact with the second face;
compressing the first photovoltaic device portion and second photovoltaic device portion at a pressure sufficient to fuse the first perovskite material to the second perovskite material.
