Scalable open-air processing of electron transport layers for perovskite solar cells
Abstract/Contents
- Abstract
- This dissertation explores open-air processing of perovskite solar cells, specifically on the electron transport layer deposited above the perovskite layer. An inorganic titanium dioxide electron transport layer is first explored using an open-air chemical vapor deposition process. The titanium dioxide demonstrates improved mechanical stability and barrier properties against ingress of environmental species. The development of an open-air ultrasonic spray process for the deposition of an organic electron transport bilayer on top of perovskite is presented next. The successful spray deposition and resultant film quality is highly dependent on solvent composition and the inclusion of a near-infrared heating module to accelerate film drying. In addition, the second half of the bilayer is an ultrathin (sub 10 nm) film that requires sophisticated characterization to ensure that the film is of the appropriate thickness and surface morphology. The sprayed organic electron transport bilayer is integrated into perovskite solar cell devices exhibiting high efficiencies > 20%. Finally, the spray process is included in a previously developed cost model resulting in significant manufacturing cost savings.
