A method for manufacturing a photovoltaic device. The method comprises fabricating a first photovoltaic device portion with a first photoactive layer having a first face comprising a first perovskite precursor material; fabricating a second photovoltaic device portion with a second photoactive layer having a second face comprising a second perovskite material or a second perovskite precursor material; arranging the first photovoltaic device portion and the second photovoltaic device portion such that the first face is in contact with the second face; and compressing the first photovoltaic device portion and the second photovoltaic device portion at a pressure sufficient to fuse the first perovskite precursor material to the second perovskite material or the second perovskite precursor material.
