Highly efficient and rapid manufactured perovskite solar cells via Flash InfraRed Annealing

Abstract

This work unveils how to quickly manufacture highly efficient and stable perovskite solar cells (PSCs) using the Flash InfraRed Annealing (FIRA) method. With FIRA, the titanium oxide mesoscopic layer can be synthesized in only 10 min, and the synthesis of the perovskite film takes a few seconds. All is done in one place and continuously, allowing a better synchronization of the manufacturing process with high reproducibility. For this purpose, a new perovskite composition based on formamidinium (FA) lead iodide combined with a passivation post-treatment has been optimized, improving the film quality for PSCs. Here we show a step forward into the industrial application of the FIRA method in PSCs.

Perovskite solar cell
A perovskite solar cell (PSC) is a type of solar cell that includes a perovskite-structured compound, most commonly a hybrid organic–inorganic lead or tin halide-based material as the light-harvesting active layer. Perovskite materials, such as methylammonium lead halides and all-inorganic cesium lead halide, are cheap to produce and simple to manufacture. Solar-cell efficiencies of laboratory-scale devices using these materials have increased from 3.8% in 2009 to 25.
Solar cell
A solar cell, or photovoltaic cell, is an electronic device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical phenomenon. It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Individual solar cell devices are often the electrical building blocks of photovoltaic modules, known colloquially as solar panels.
Dye-sensitized solar cell
A dye-sensitized solar cell (DSSC, DSC, DYSC or Grätzel cell) is a low-cost solar cell belonging to the group of thin film solar cells. It is based on a semiconductor formed between a photo-sensitized anode and an electrolyte, a photoelectrochemical system. The modern version of a dye solar cell, also known as the Grätzel cell, was originally co-invented in 1988 by Brian O'Regan and Michael Grätzel at UC Berkeley and this work was later developed by the aforementioned scientists at the École Polytechnique Fédérale de Lausanne (EPFL) until the publication of the first high efficiency DSSC in 1991.
