Tunable band gaps of Co3−xCuxO4 nanorods with various Cu doping concentrations

Chun Te Ho et.al, RSC Adv., 2014,4, 20053-20057 IF: 4.036 (2021)

Co3−xCuxO4 nanorods with a crystalline structure were synthesized via a solution process in this study. The Co3−xCuxO4 nanorods exhibit dual direct bandgaps and could be adjusted to 1.3–1.5 eV, and 2.55–3.5 eV by using different Cu-doping concentrations. The Co3−xCuxO4 nanorods show an absorption coefficient of ∼104 cm−1 which increases with the increase of the Cu doping concentration.

SELF-ASSEMBLYNANO-COMPOSITE SOLAR CELL

Che Ning Yeh, Chun-Te Ho et.al, U.S. patent No.:8937241

A self-assembly nano-composite solar cell comprises a substrate, a first electrode layer, a composite absorption layer and a second electrode layer. The first electrode layer is formed on the substrate. The composite absorption layer is formed over the first electrode layer and includes a plurality of vertical nano-pillars, a plurality of gaps each formed between any two adjacent nano-pillars, and a plurality of bismuth sulfide nano-particles filled into the gaps and attached to the nano-pillars. The second electrode layer is formed over the composite absorption layer. Through etching and soaking in solutions, the composite absorption layer with nano-pillars and bismuth sulfide nano-particles is fabricated to form a self-assembly nano-composite solar cell having high power conversion efficiency.
