Title: | Nanophotonic front electrodes for perovskite solar cells | Authors: | Paetzold, Ulrich Wilhelm Qiu, Weiming Finger, Friedhelm POORTMANS, Jef Cheyns, David |
Issue Date: | 2015 | Publisher: | AMER INST PHYSICS | Source: | APPLIED PHYSICS LETTERS, 106 (17) | Abstract: | In less than 3 years' time, a vast progress in power conversion efficiencies of organometal halide perovskite solar cells has been achieved by optimization of the device architecture, charge transport layers, and interfaces. A further increase in these efficiencies is expected from an improvement in the optical properties via anti-reflection coatings and nanophotonic light management concepts. In this contribution, we report on the development and implementation of a nanophotonic front electrode for perovskite solar cells. The nanostructures were replicated via the versatile and large-area compatible UV-nanoimprint lithography. The shallow design of the used transparent and conductive nanostructures enabled easy integration into our solution-based baseline process. Prototype methylammonium lead iodide perovskite solar cells show an improvement of 5% in short-circuit current density and an improvement from 9.6% to 9.9% in power conversion efficiency compared to the flat reference device.
