چکیده
Low-temperature processed carbon-based perovskite solar cells have received great attention due to low-cost, high stability, and simple preparation processes that can be employed in large-scale manufacturing. Carbon paste is deposited by techniques such as doctor blading or screen printing. However, solvents from this damage the underlying layers resulting poor performance of cells. Furthermore, carbon not an ideal hole-selective contact. To overcome these issues, antisolvent treatment combined with deposition a polymeric hole conductor. Specifically, poly(3-hexylthiophene) (P3HT), added into chlorobenzene antisolvent, improves morphology reduces interfacial carrier recombination. As result, power conversion efficiency (PCE) device structure SnO2/MAPbI3/P3HT/carbon increases 12.16% 10.6% pristine devices without P3HT, using pure antisolvent. For poly(triarylamine) conductor same method, PCE only slightly 11.1%. After 260 h thermal stress at 82 °C, P3HT-additive improve up 13.2% air maintain 91% their initial over 800 h.

Enhanced Ambient Stability of Efficient Perovskite Solar Cells by Employing a Modified Fullerene Cathode Interlayer
A novel fullerene cathode interlayer is employed to facilitate the fabrication of stable and efficient perovskite solar cells. This modified fullerene surfactant significantly increases air stability of the derived devices due to its hydrophobic characteristics to enable 80% of the initial PCE to be retained after being exposed in ambient condition with 20% relative humidity for 14 days.

Lead halide perovskite solar cells have recently attracted tremendous attention because of their excellent photovoltaic efficiencies. However, the poor stability of both the perovskite material and the charge transport layers has so far prevented the fabrication of devices that can withstand sustained operation under normal conditions. Here, we report a solution-processed lead halide perovskite...

Organo lead halide perovskite materials like methylammonium lead iodide (CH3NH3PbI3) and formamidinium lead iodide (HC(NH2)2PbI3) show superb opto-electronic properties. Based on these perovskite light absorbers, power conversion efficiencies of the perovskite solar cells employing hole transporting layers have increased from 9.7% to 20.1% within just three years. Thus, it is apparent that pero...
