“…Ultimately, it has been suggested that perovskite/Si monolithic tandems can surpass 35% efficiency through careful photon management. 10 In summary, we have demonstrated a 1 cm 2 , 2-terminal monolithically-integrated metal-halide perovskite/Si multijunction solar cell. The monolithic integration is enabled by a Si-based tunnel junction fabricated directly on top of the bottom Si sub-cell emitter and by incorporating a semitransparent silver nanowire-based top electrode.…”

“…5 To make PV modules with higher efficiency than market-leading c-Si while leveraging existing c-Si manufacturing capacity, Si-based tandem approaches have been proposed. [6][7][8][9][10] The top sub-cell in a silicon-based tandem should have a band gap between 1.6 and 1.9 eV. 11 However, very few materials exhibit high open-circuit voltages (V OC ) within this band gap range.…”

With the advent of efficient high-bandgap metal-halide perovskite photovoltaics, an opportunity exists to make perovskite/silicon tandem solar cells. We fabricate a monolithic tandem by developing a silicon-based interband tunnel junction that facilitates majority-carrier charge recombination between the perovskite and silicon sub-cells. We demonstrate a 1 cm2 2-terminal monolithic perovskite/silicon multijunction solar cell with a VOC as high as 1.65 V. We achieve a stable 13.7% power conversion efficiency with the perovskite as the current-limiting sub-cell, and identify key challenges for this device architecture to reach efficiencies over 25%.

“…Ellipsometry measurements were done in reflection mode using a Horiba Jobin Yvon UVISEL iHR320 polarization modulation ellipsometer under incident angles of 50°, 60° and 70° with a spectral resolution of 10 meV similarly as in [24]. The dielectric function is identified indirectly by fitting the data with a suitable model.…”

“…The goal of this paper is to identify the most promising experimentally feasible devices. For this reason we restrict ourselves to CH 3 NH 3 PbI 3 as it is the state-of-the-art material that demonstrates high conversion efficiencies [19,23] and has a bandgap that is sufficiently close to the optimum to still allow for high efficiencies of tandem structures in combination with c-Si [24].…”

Abstract:In this study we analyze and discuss the optical properties of various tandem architectures: mechanically stacked (four-terminal) and monolithically integrated (two-terminal) tandem devices, consisting of a methyl ammonium lead triiodide (CH 3 NH 3 PbI 3 ) perovskite top solar cell and a crystalline silicon bottom solar cell. We provide layer thickness optimization guidelines and give estimates of the maximum tandem efficiencies based on state-of-the-art sub cells. We use experimental complex refractive index spectra for all involved materials as input data for an in-house developed optical simulator CROWM. Our characterization based simulations forecast that with optimized layer thicknesses the fourterminal configuration enables efficiencies over 30%, well above the current single-junction crystalline silicon cell record of 25.6%. Efficiencies over 30% can also be achieved with a two-terminal monolithic integration of the sub-cells, combined with proper selection of layer thicknesses.

Carbon nanotubes have a variety of remarkable electronic and mechanical properties that, in principle, lend them to promising optoelectronic applications. However, the field has been plagued by heterogeneity in the distributions of synthesized tubes and uncontrolled bundling, both of which have prevented nanotubes from reaching their full potential. Here, a variety of recently demonstrated solution-processing avenues is presented, which may combat these challenges through manipulation of nanoscale structures. Recent advances in polymer-wrapping of single-walled carbon nanotubes (SWNTs) are shown, along with how the resulting nanostructures can selectively disperse tubes while also exploiting the favorable properties of the polymer, such as light-harvesting ability. New methods to controllably form nanoengineered SWNT networks with controlled nanotube placement are discussed. These nanoengineered networks decrease bundling, lower the percolation threshold, and enable a strong enhancement in charge conductivity compared to random networks, making them potentially attractive for optoelectronic applications. Finally, SWNT applications, to date, in organic and perovskite photovoltaics are reviewed, and insights as to how the aforementioned recent advancements can lead to improved device performance provided.
