Perovskite – R&D&i project of perovskite-based photovoltaic solar cells
The Perovskita project of the Department of Photovoltaics is a line of Research, Development and Innovation that aims to obtain high-efficiency and low-cost photovoltaic cells based on the use of organic/inorganic hybrid materials, as the active layer (or light catcher).
This technology, which has evolved rapidly over the last decade, now holding laboratory efficiency records of more than 20 per cent, is particularly attractive because of its relatively simple production processes. These processes are based on the arrangement of their constituent elements in the form of thin layers deposited on transparent substrates, which reduces the costs of both materials and manufacturing processes.
The objectives of the project are to achieve advances that will allow the inclusion of this technology in the commercial sector. To this end, the work focuses on three areas:
- Improvements in the synthesis of the structures of deposited layers, which make it possible to increase the efficiency of the cells, reducing light and electrical losses.
- Study of the deposition methods of the layers that configure the structure of the photovoltaic device itself.
- Evaluation of the behavior of this type of structure over time and in relation to its exposure to atmospheric agents.
The research and development work under this project has enabled the laboratory to present its results in various forums, through participation in public conferences and publication of articles. The latest contributions are listed below, in chronological order:
- A one-step deposition method assisted with non polar washing solvent treatment for producing uniform thin layers of perovskite validated through ellipsometry. This article summarizes the methodology developed by the solar cell laboratory (SiCellLab), which has been validated using spectral ellipsometric characterization, in order to evaluate the optical properties and thickness of thin films of methylammonium lead iodide (CH3NH3PBI3) deposited from solutions of their chemical precursors, through spin coating on glass substrates by the one-step method, assisted with non-polar solvent washing treatment[ Local] [ EUPVSEC]
- Optimizing the deposition of thin layers of organic-inorganic hybrid perovskite methylammonium lead iodide (CH3NH3PbI3) on large surfaces through their optical properties. The article proposes a method to optimize the deposition of perovskite layers on large surfaces, up to 75 mm x 75 mm. [Local] [EUPVSEC]

- Adaptation of a crystalline silicon solar cell laboratory to produce perovskite solar devices. It shows the adaptations carried out in the photovoltaics laboratory, originally designed for the research of crystalline silicon cells, in this new line of research. [Local] [EUPVSEC]
This action is co-financed by the MEDI-FDCAN Programme 2016-2025 and is included in the Strategic Framework for Island Development (MEDI) 2016-2025 of the Island Council of Tenerife.
