Hybrid organic-inorganic perovskite-based solar cells have demonstrated to be a valuable candidate for multijunction solar panels due to its tunable chemical composition and absorption characteristics. Since 2009, the single junction record efficiency passed from 3.8% to 25.2%. Moreover, multijunction perovskite-based solar cells have already outperformed monocrystalline silicon record of 26.7%, with 27.1% for a 4-terminal configuration and 28% for a 2-terminal one.
Furthermore, perovskites make a perfect market fit due to its low light intensity performances, low-cost and earth-abundant materials composition and adaptability on flexible or rigid substrates.
However, the record holder perovskite device does not couple perfectly with Silicon or CIGS absorption characteristics that limits the potential multijunction efficiency. For this reason, perovskites with optimized optical characteristics are being investigated and many advances lead to the latest multijunction record cells. Nevertheless, further optical and electrical improvements are required to push efficiencies even higher.
In this scope, this work aims to investigate newer compositions and deposition techniques towards 30% or higher efficiencies. The work will consist in the fabrication of solar photovoltaics cells through solution processed state of the art techniques such as spin and/or blade coating. The electrical performances of the devices are then characterized through IV curves, EQE and absorption measurements while the consistency and conformity of the deposited perovskite will be analyzed via photoluminescence (PL and TRPL) and Scanning Electron Microscope (SEM) images.
The work will be conducted in the newly built laboratories at imec in EnergyVille, Genk, working in one of the world’s premier research centers in nanotechnology.
