“…Overall, the plasmonic BR results in a high photocurrent of 26.3 mA/cm 2 which is comparable to the textured BR (26.7 mA/cm 2 ). The photocurrent of 26.3 mA/cm 2 is considerably higher than the previous works on plasmonic light trapipng, [11][12][13][14] thanks to the low parasitic absorption and broad angular scattering.…”

“…Such a deterioration of FF was also commonly observed in other reports. [10][11][12][13][14] Although the top surface of the Ag NPs is flattened, the edges of the Ag NPs are still relatively steep. The sharp valleys around the Ag NPs can create cracks (porous defective material) near the n/i interface and inside the intrinsic layer.…”

“…[1][2][3][4][5] Recently, plasmonic metal nanoparticles have attracted extensive interest to further improve the light trapping in solar cells since metal nanoparticles can efficiently scatter the incident light into absorber layer. [6][7][8][9][10][11][12][13][14] Enhanced photocurrent in lc-Si:H solar cells has been demonstrated using periodic metallic gratings and random metal nanoparticles as rear reflectors, which here we refer to as plasmonic back reflector (BR). By depositing lc-Si:H solar cells on periodic metallic reflector, Paetzold et al demonstrated that the photocurrent can be increased to 21.0 mA/ cm 2 , compared to 17.7 cm/cm 2 for a planar cell.…”

“…[11][12][13][14] One of the main reasons is the considerable parasitic absorption in the plasmonic BR. Scattering mainly into low angles (close to the surface normal) is another possible factor limiting the light trapping performance.…”

We show experimentally that the photocurrent of thin-film hydrogenated microcrystalline silicon (lc-Si:H) solar cells can be enhanced by 4.5 mA/cm 2 with a plasmonic back reflector (BR). The light trapping performance is improved using plasmonic BR with broader angular scattering and lower parasitic absorption loss through tuning the size of silver nanoparticles. The lc-Si:H solar cells deposited on the improved plasmonic BR demonstrate a high photocurrent of 26.3 mA/cm 2 which is comparable to the state-of-the-art textured Ag/ZnO BR. The commonly observed deterioration of fill factor is avoided by using lc-SiO x :H as the n-layer for solar cells deposited on plasmonic BR. V C 2013 AIP Publishing LLC [http://dx

One of the potential applications of metal nanostructures is light trapping in solar cells, where unique optical properties of nanosized metals, commonly known as plasmonic effects, play an important role. Research in this field has, however, been impeded owing to the difficulty of fabricating devices containing the desired functional metal nanostructures. In order to provide a viable strategy to this issue, we herein show a transfer printing-based approach that allows the quick and low-cost integration of designed metal nanostructures with a variety of device architectures, including solar cells. Nanopillar poly(dimethylsiloxane) (PDMS) stamps were fabricated from a commercially available nanohole plastic film as a master mold. On this nanopatterned PDMS stamps, Ag films were deposited, which were then transfer-printed onto block copolymer (binding layer)-coated hydrogenated microcrystalline Si (µc-Si:H) surface to afford ordered Ag nanodisk structures. It was confirmed that the resulting Ag nanodisk-incorporated µc-Si:H solar cells show higher performances compared to a cell without the transfer-printed Ag nanodisks, thanks to plasmonic light trapping effect derived from the Ag nanodisks. Because of the simplicity and versatility, further device application would also be feasible thorough this approach. Video LinkThe video component of this article can be found at

A logical next step for achieving a cost price reduction per Watt peak of photovoltaics (PV) is multijunction PV devices. In two-terminal multijunction PV devices, the photo-current generated in each subcell should be matched. Intermediate reflective layers (IRLs) are widely employed in multijunction devices to increase reflection at the interface between subcells to enhance current generation in the subcell(s) positioned before the IRL, in reference to the incident light. In this work, the results of over 65 multijunction devices are presented, in order to explore the effect of different current matching approaches. The influence of variations in absorber thickness as well as thickness variations of different IRLs based on silicon-oxide, various transparent conductive oxides (TCO), and metallic layers on all-silicon multijunction PV devices is studied. Specifically, hybrid, 2-terminal, monolithically integrated silicon heterojunction (SHJ) and thin film nanocrystalline silicon (nc-Si:H) and amorphous silicon (a-Si:H) tandem and triple junction devices are processed. Based on these experiments, certain design rules for optimal current matching operation in multijunction devices are formulated. Finally, taking these design rules into account, record allsilicon multijunction devices are processed. Conversion efficiencies close 15% and V oc ≈ 2 V are demonstrated for triple junction SHJ/nc-Si:H/a-Si:H devices. Such conversion efficiencies for a wireless, high-voltage wafer-based all-silicon 2-terminal multijunction PV device opens the way for efficient autonomous solar-to-fuel synthesis systems as well as other wireless innovative approaches in which the multijunction solar cell is used not only as a photovoltaic current-voltage generator, but also as an ion-exchange membrane, electrochemical catalysts, and/or optical transmittance filter.
