Breakthrough synthesis method improves solar cell stability

Solar cell efficiency has significantly increased in recent years due to the use of light-absorbing materials like halide perovskites. However, the challenge lies in reliably producing these materials at a large scale. Researchers at Rice University, along with collaborators from Northwestern University, the University of Pennsylvania, and the University of Rennes, have developed a process known as kinetically controlled space confinement. This method enables the precise control of temperature and crystallization duration to create 2D perovskite-based semiconductor layers with the ideal thickness and purity, potentially improving the stability and reducing the cost of emerging technologies such as optoelectronics and photovoltaics. These 2D perovskite crystals can exhibit higher quantum well thickness (referred to as 'n value') than traditional methods, resulting in narrower band gaps and enhanced electrical conductivity, making them valuable for electronic devices.
Traditionally, synthesizing 2D perovskite materials with higher 'n values' led to mixed phases and uneven crystal growth, affecting the material's reliability. The researchers designed a method to slow down the crystallization process and gradually adjust the kinetics parameters, achieving a phase-pure synthesis of 2D halide perovskite layers. This breakthrough not only enhances the purity of the crystals but also provides a new approach for high 'n value' crystal synthesis, offering promising prospects for stable and commercially viable applications in solar cells, optoelectronic devices, and fundamental light-matter interactions.
