Title: Perovskite ink with wide processing window for scalable high-efficiency solar cells

Abstract

Perovskite solar cells have made tremendous progress using laboratory-scale spin-coating methods in the past few years owing to advances in controls of perovskite film deposition. However, devices made via scalable methods are still lagging behind state-of-the-art spin-coated devices because of the complicated nature of perovskite crystallization from a precursor state. Here we demonstrate a chlorine-containing methylammonium lead iodide precursor formulation along with solvent tuning to enable a wide precursor-processing window (up to ~8 min) and a rapid grain growth rate (as short as ~1 min). Coupled with antisolvent extraction, this precursor ink delivers high-quality perovskite films with large-scale uniformity. The ink can be used by both spin-coating and blade-coating methods with indistinguishable film morphology and device performance. Using a blade-coated absorber, devices with 0.12-cm 2 and 1.2-cm 2 areas yield average efficiencies of 18.55% and 17.33%, respectively. As a result, we further demonstrate a 12.6-cm 2 four-cell module (88% geometric fill factor) with 13.3% stabilized active-area efficiency output.

  • We have applied an optical splitting system in order to achieve very high conversion efficiency for a full spectrum multi-junction solar cell. This system consists of multiple solar cells with different band gap optically coupled via an “optical splitter.” An optical splitter is a multi-layered beam splitter with very high reflection in the shorter-wave-length range and very high transmission in the longer-wave-length range. By splitting the incident solar spectrum and distributing it to each solar cell, the solar energy can be managed more efficiently. We have fabricated optical splitters and used them with a wide-gap amorphous silicon (a-Si) solar cellmore » or a CH{sub 3}NH{sub 3}PbI{sub 3} perovskite solar cell as top cells, combined with mono-crystalline silicon heterojunction (HJ) solar cells as bottom cells. We have achieved with a 550 nm cutoff splitter an active area conversion efficiency of over 25% using a-Si and HJ solar cells and 28% using perovskite and HJ solar cells.« less
  • We review our recent progress toward realizing future low-cost, high-efficiency, and scalable organic solar cells (OSCs). First, we show that the transparent electrodes based on metallic nanostructure is a strong candidate as a replacement of conventional indium tin oxide (ITO) electrode due to their superior properties, such as high optical transparency, good electrical conductivity, and mechanical flexibility, and the versatility that these properties can be adjusted independently by changing the linewidth and thickness of the metal grid structure. Furthermore, we exploited the unique optical properties due to the excitation of surface plasmon resonance by the metallic nanogratings to enhance themore » light absorption of organic semiconductors, and demonstrated enhanced power conversion efficiency than devices made using ITO electrode. In addition, we also investigated a new device fabrication process with a focus on the photoactive layer formation, which produces the most optimum bulk-heterojunction morphology compared with conventional annealing-based methods. Finally, we successfully demonstrated that these approaches are scalable to large-area and high-speed roll-to-roll processes. We believe that the works highlighted in this paper represent one step forward to realizing low-cost, high-efficiency, and large-area OSCs.« less
  • High mobility hydrogenated indium oxide is investigated as a transparent contact for thin film Cu(In,Ga)Se{sub 2} (CIGS) solar cells. Hydrogen doping of In{sub 2}O{sub 3} thin films is achieved by injection of H{sub 2}O water vapor or H{sub 2} gas during the sputter process. As-deposited amorphous In{sub 2}O{sub 3}:H films exhibit a high electron mobility of ∼50 cm{sup 2}/Vs at room temperature. A bulk hydrogen concentration of ∼4 at. % was measured for both optimized H{sub 2}O and H{sub 2}-processed films, although the H{sub 2}O-derived film exhibits a doping gradient as detected by elastic recoil detection analysis. Amorphous IOH films aremore » implemented as front contacts in CIGS based solar cells, and their performance is compared with the reference ZnO:Al electrodes. The most significant feature of IOH containing devices is an enhanced open circuit voltage (V{sub OC}) of ∼20 mV regardless of the doping approach, whereas the short circuit current and fill factor remain the same for the H{sub 2}O case or slightly decrease for H{sub 2}. The overall power conversion efficiency is improved from 15.7% to 16.2% by substituting ZnO:Al with IOH (H{sub 2}O) as front contacts. Finally, stability tests of non-encapsulated solar cells in dry air at 80 °C and constant illumination for 500 h demonstrate a higher stability for IOH-containing devices.« less
  • In order to improve the efficiency of silicon solar cells, minority carrier recombination must be reduced. Designs for solar cells which minimize recombination are discussed. To reduce surface recombination, use of a heterojunction structure with a wide-bandgap semiconductor lattice-matched to the silicon was explored. Heterojunction windows of zinc sulfide were fabricated and tested, and measurements of solar cell open circuit voltage, dark current, and short-wavelength quantum efficiency confirm that the surface recombination velocity is reduced from that of the bare surfaces. In order to reduce bulk recombination, a very thin cell is proposed, with a new geometrical optical confinement (lightmore » trapping) system to maintain high values of short-circuit current despite the lower cell thickness. Analysis of this design indicates that the efficiency of light trapping is extremely high, with trapped optical pathlengths of better than 50 times the width of the cell. Finally, improvements in solar cell performance require non-destructive techniques for measuring the lifetime of minority carriers in the initial wafers as well as in finished cells. A new method of directly measuring the carrier recombination in silicon was demonstrated.« less
