Evaluation of active layer thickness influence in long-term stability and degradation mechanisms in csfapbibr perovskite solar cells

Perovskite solar cells (PSCs) have become very popular due to the high efficiencies achieved. Nevertheless, one of the main challenges for their commercialization is to solve their instability issues. A thorough understanding of the processes taking place in the device is key for the development of this technology. Herein, J-V measurements have...

The dominant role of memory-based capacitive hysteretic currents in operation of photovoltaic perovskites

The potential opportunities of perovskite-based technology to further advance in the photovoltaic field and implement an extensive industrial application, will mainly depend on whether some of its weaknesses, such as current density-voltage (J−V) hysteresis, can be overcome. In this sense, a critical aspect is the understanding and the...

Analysis of dynamical mechanisms of CsFAPbIBr perovskite solar cells

Perovskite Solar Cells (PSC) have attracted great attention due to the high efficiencies achieved in the past few years (up to 24.2 %). Perovskite semiconductors show excellent light absorption and large charge-carrier mobilities. In addition, device fabrication is low cost and easily up-scalable. However, the current density-voltage curve (J-V)...
