    • 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 polar solvent, at least one binder, and at least one Group IB and/or IIIA hydroxide. 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.
    • 提供了用于形成吸收层的方法和装置。 在一个实施方案中,提供了一种方法,其包括在基底上沉积溶液以形成前体层。 溶液包含至少一种极性溶剂,至少一种粘合剂和至少一种IB族和/或IIIA型氢氧化物。 在一个或多个步骤中处理前体层以形成光伏吸收层。 在一个实施方案中,吸收层可以通过将前体层加工成固体膜,然后在至少含有元素周期表第VIA族元素的气氛中使固体膜热反应形成光伏吸收层来产生。 任选地,吸收层可以通过前体层在至少含有周期表第VIA族元素的气氛中进行热反应来加工,以形成光伏吸收层。
