Polytetrafluoroethylene (PTFE) filled with certain alumina additives has wear rates over four orders of magnitude lower than unfilled PTFE. The mechanisms for this wear reduction have remained a mystery. In this work, we use a combination of techniqu

In Cu2ZnSn(S,Se)4 (CZTSSe) thin film solar cells, it is commonly accepted that a Cu-poor and Zn-rich composition is required for high-efficiency devices. However, the finding from our nanoparticle-derived CZTSSe photovoltaic (PV) devices challenges t

A new solution-based method to fabricate Cu(2)ZnSn(S,Se)(4) (CZTSSe) thin films is presented. Binary and ternary chalcogenide nanoparticles were synthesized and used as precursors to form CZTSSe thin films. The composition of the CZTSSe films can be

Large-scale deployment of currently favored high-efficiency, thin-film photovoltaic materials (e.g., CdTe, CIGS) may be resource-limited due to dependence upon relatively non-abundant elements (e.g., In, Ga, Te). As a result, Cu 2 ZnSn(S, Se) 4 (CZTS
