Self-assembly nano-composite solar cell
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.
