摘要

We report the considerable enhancement of the solar power conversion efficiency (PCE) in dye-sensitized solar cells (DSSCs) using polydimethylsiloxane (PDMS) patterned with a novel biomimetic compound architecture (CA) (i.e., hierarchical nanobumps/microcone arrays) with light-harvesting and self-cleaning functions as a protective cover-layer. The CA-PDMS is transferred from a nanoporous anodic alumina oxide mold by a facile and cost-effective soft imprint lithography via a microcone-patterned sapphire substrate. A lamination of CA-PDMS on the glass leads to increased total and diffuse transmittance properties (i.e., antireflection and light scattering effects), simultaneously, compared to bare glass over a wide wavelength range of 350-800 nm, exhibiting a much larger solar weighted total transmittance (TSW) value of ~94% and an average haze ratio (HA) value of ~49.7% (TSW z 90.4% and HA z 1.4% for bare glass). In addition, sand grains on the hydrophobic surface with a water contact angle of ~134 are clearly washed by rolling down water droplets (i.e., self-cleaning effect). To simply demonstrate the device applicability, CA-PDMS is introduced onto an outer surface of the front glass substrate in a DSSC. The resulting DSSC with CA-PDMS exhibits a boosted PCE value of ~8.24% mainly due to a strongly increased short-circuit current density (JSC) value of ~18.11 mA cm~(-2) compared to the reference DSSC with bare glass (PCE z 7.45% and JSC z 16.37 mA cm~(-2)) under AM1.5G illumination, indicating a large PCE enhancement percentage value of ~10.7%.
