Efficiency improvement of Si quantum dot solar cells by activation with boron implantation

Fast room-temperature functionalization of silicon nanoparticles using alkyl silanols

“…Semiconductor nanoparticles have proven to be useful for many different applications, including bio-imaging, 1-3 LEDs, [4][5][6] and solar cells. [7][8][9][10][11][12] Silicon nanoparticles (Si NPs) are, in this regard, particularly interesting, due to their low toxicity and the high natural abundance of the starting material. 13,14 However, several issues have so far stood in the way of their widespread use.…”

Improvement of power conversion efficiency by a stepwise band-gap structure for silicon quantum dot solar cells

“…When the boron chip was located at the center of the sputtering area, the doping concentration of boron was maximized (1.51 × 10 22 atoms cm −3 ). The doping concentration of boron was measured using secondary ion mass spectrometry (SIMS) and B-implanted Si reference material (NIST SRM 2137) [26].…”
