Synthesis, Surface Functionalization of Germanium Nanoparticles, and Their Application in Polymer Hybrid Solar Cells
DownloadSpring 2020
Germanium nanoparticles (GeNPs) have immense potential in various applications, such as opto-electronics, batteries, bioimaging, etc. Germanium has a small band gap (0.67 eV in bulk), large exciton Bohr radius (~24 nm), high absorption coefficient (ca. 2.0 × 105 cm 1 at 2 eV), and high carrier...
