Iterative image reconstruction methods based on conventional total variation (TV) for computed tomography imaging may have limitations for specific applications or situations, such as images with non-sparse gradient parts, complicated textures, or severely contaminated data sets. For these cases, encoders in optimization programs with only TV-based terms may not be sufficient for high-precision image...
CdS thin films are a promising electron transport layer in PbS colloidal quantum dot (CQD) photovoltaic devices. Some traditional deposition techniques, such as chemical bath deposition and RF (radio frequency) magnetron sputtering, have been employed to fabricate CdS films and CdS/PbS CQD heterojunction photovoltaic devices. However, their power conversion efficiencies (PCEs) are moderate compared...
