Methods and devices are provided for forming an absorber layer. In one embodiment, a method is provided comprising of depositing a solution on a substrate to form a precursor layer. The solution comprises of at least one equilibrium and/or near equilibrium material. The precursor layer is processed in one or more steps to form a photovoltaic absorber layer. In one embodiment, the absorber layer may be created by processing the precursor layer into a solid film and then thermally reacting the solid film in an atmosphere containing at least an element of Group VIA of the Periodic Table to form the photovoltaic absorber layer. Optionally, the absorber layer may be processed by thermal reaction of the precursor layer in an atmosphere containing at least an element of Group VIA of the Periodic Table to form the photovoltaic absorber layer. |
