The Perovskite project of ITER’s photovoltaics department is a line of research, development and innovation that aims to develop high-efficiency, low-cost photovoltaic cells using organic-inorganic hybrid materials as the active (light-capturing) layer.
This technology, which has evolved rapidly over the past decade, having achieved record-breaking efficiency levels in laboratory conditions of over 20%, is particularly attractive because of the relative simplicity of the processes involved in developing it. These consist in arranging its constituent elements in the form of thin layers on transparent substrates, which reduces the cost of both the materials and the manufacturing processes.
The aims of the project are centred around improving the technology with a view to harnessing its commercial applications. To this end, the project will focus on three areas:
- Improving the synthesis of the structures of the deposited layers, to ensure greater photovoltaic cell efficiency by reducing light-capturing and electrical losses.
- Research into the methods of layer deposition related to the structure of the photovoltaic device itself.
- Assessment of the performance of such structures over time and in response to their exposure to the environment.
Research results from this project were accepted for publication at different forums and publications. The following contributions are listed in chronological order:
- Optimizing the deposition of thin layers of organic-inorganic hybrid perovskite methylammonium lead iodide (CH3NH3PbI3) on large surfaces through their optical properties. The present paper proposes a method for optimizing the deposition of thin layers of organic-inorganic hybrid perovskite methylammonium lead iodide (CH3NH3PbI3) on large surfaces (up to 75 mm x 75 mm) via spin coating procedures.
