Abstract

High efficiency Si-organic hybrid solar cells employing AgNW/PEDOT:PSS bilayer transparent electrode has been demonstrated, by combining with hierarchical texturing of Si and dry contact-printed ultrathin siloxane layers at interfaces. The optimized bilayer electrode has very low sheet resistance of ∼25 Ohm/sq and high enough optical transparency of >85% at the same time. It should be noted that the results have been obtained without adopting any high temperature doping or vacuum-based deposition steps, which secures the expected advantages, simplicity and low-cost capability, of Si-organic hybrid cells. The high efficiency obtained via low temperature, cost-effective processes can now make the Si-organic hybrid cells as a viable candidate for post-Si photovoltaics.
