title = "High-performance thermoelectric silver selenide thin films cation exchanged from a copper selenide template",
abstract = "Ag2Se has potentially excellent thermoelectric (TE) performance as an n-type semiconductor. It has been considered a promising alternative to Bi-Te alloys and other commonly used yet toxic and/or expensive TE materials. To optimize the TE performance of Ag2Se, recent research has focused on fabricating nanosized Ag2Se. However, synthesizing Ag2Se nanoparticles involves energy-intensive and time-consuming techniques with poor yield of final product. In this work, we report a low-cost, solution-processed approach that enables the formation of Ag2Se thin films from Cu2-xSe template films via cation exchange at room temperature. Our simple two-step method involves fabricating Cu2-xSe thin films by the thiolamine dissolution of bulk Cu2Se, followed by soaking Cu2-xSe films in AgNO3 solution and annealing to form Ag2Se. We report a maximum power factor (PF) of 825 µWm-1K-2 for our best-performing Ag2Se thin-film. This high PF has been achieved via full solution processing without hot-pressing.",
