Title: Acid additives enhancing the conductivity of spiro-OMeTAD toward high-efficiency and hysteresis-less planar perovskite solar cells

Abstract

A general doping strategy, using a wide range of acids with different p K a values as additive, is demonstrated to enhance the conductivity of spiro-OMeTAD, the dominant hole transport material in perovskite solar cells (PSCs). Here, hysteresis-less planar PSCs with ≈19% efficiency and better open-circuit voltage and fill factor is achieved with acid doped spiro-OMeTAD.

  • Organo-metal halide perovskite solar cells based on planar architecture have been reported to achieve remarkably high power conversion efficiency (PCE, >16%), rendering them highly competitive to the conventional silicon based solar cells. A thorough understanding of the role of each component in solar cells and their effects as a whole is still required for further improvement in PCE. In this work, the planar heterojunction-based perovskite solar cells were simulated with the program AMPS (analysis of microelectronic and photonic structures)-1D. Simulation results revealed a great dependence of PCE on the thickness and defect density of the perovskite layer. Meanwhile, parameters includingmore » the work function of the back contact as well as the hole mobility and acceptor density in hole transport materials were identified to significantly influence the performance of the device. Strikingly, an efficiency over 20% was obtained under the moderate simulation conditions.« less
  • We report on high-efficiency planar heterojunction perovskite solar cells (PSCs) employing Ni-doped alpha-Fe2O3 as electron-transporting layer (ETL). The suitable addition of nickel (Ni) dopant could enhance the electron conductivity as well as induce downward shift of the conduction band minimum for alpha-Fe2O3, which facilitate electrons injection and transfer from the conduction band of the perovskite. As a consequence, a substantial reduction in the charge accumulation at the perovskite/ETL interface makes the device much less sensitive to scanning rate and direction, i.e., lower hysteresis. With a reverse scan for the optimized PSC under standard AM-1.5 sunlight illumination, it generates a competitivemore » power conversion efficiency (PCE) of 14.2% with a large short circuit current (J(sc)) of 22.35 mA/cm(2), an open circuit photovoltage (V-oc) of 0.92 V and a fill factor (FF) of 69.1%. Due to the small J-V hysteresis behavior, a higher stabilized PCE up to 11.6% near the maximum power point can be reached for the device fabricated with 4 mol% Ni-doped alpha-Fe2O3 ETL compared with the undoped alpha-Fe2O3 based cell (9.2%). Furthermore, a good stability of devices with exposure to ambient air and high levels of ultraviolet (UV)-light can be achieved. Overall, our results demonstrate that the simple solution-processed Ni-doped alpha-Fe2O3 can be a good candidate of the n-type collection layer for commercialization of PSCs.« less
  • Organometal trihalide perovskite solar cells arguably represent the most auspicious new photovoltaic technology so far, as they possess an astonishing combination of properties. The impressive and brisk advances achieved so far bring forth highly efficient and solution processable solar cells, holding great promise to grow into a mature technology that is ready to be embedded on a large scale. However, the vast majority of state-of-the-art perovskite solar cells contains a dense TiO{sub 2} electron collection layer that requires a high temperature treatment (>450 °C), which obstructs the road towards roll-to-roll processing on flexible foils that can withstand no more than ∼150 °C.more » Furthermore, this high temperature treatment leads to an overall increased energy payback time and cumulative energy demand for this emerging photovoltaic technology. Here we present the implementation of an alternative TiO{sub 2} layer formed from an easily prepared nanoparticle dispersion, with annealing needs well within reach of roll-to-roll processing, making this technology also appealing from the energy payback aspect. Chemical and morphological analysis allows to understand and optimize the processing conditions of the TiO{sub 2} layer, finally resulting in a maximum obtained efficiency of 13.6% for a planar heterojunction solar cell within an ITO/TiO{sub 2}/CH{sub 3}NH{sub 3}PbI{sub 3-x}Cl{sub x}poly(3-hexylthiophene)/Ag architecture.« less
