该研究计划的长期目标是探索新型钙钛矿型功能材料的独特性能，并将其集成到基本的光电器件架构中，包括太阳能电池和发光二极管。钙钛矿材料提供了新的和显着的功能特性（化学，光学，光电等）。最近在纳米尺度上的合成、操作和表征方面的进展为功能材料的新发现和在几个创新应用中开发其独特性能开辟了道路。在过去的3年里，钙钛矿已经取得了惊人的成果，并在世界范围内引起了广泛的关注，作为一种有前途的材料平台，以开发低成本生产的高性能太阳能电池。在此，我们提出探索两种新型钙钛矿型材料体系：（1）多铁性Bi 2FeCrO 6氧化物和（2）金属卤化物钙钛矿MAGeI 3/MA（Bi，In）3。**三个关键的研究目标对于这项努力的成功至关重要：（1）实现合成过程的精确控制并提高所得材料系统的质量，（2）探索、理解和控制它们的基本性质，以及（3）优化它们的性质以用于与能量相关的应用和基本太阳能电池中的集成（使用例如多铁性Bi 2FeCrO 6、MAGeI 3和MA（In，Bi）I3）和发光二极管结构（特别是使用多铁性Bi 2FeCrO 6）。* 因此，所要求的财政支持将有助于为年轻研究人员的培训创造一个具有挑战性和令人兴奋的研究环境，刺激基础知识的进步，并在光电子领域取得重大技术突破。除了巨大的社会影响外，该计划还将大大有助于将加拿大定位为新兴能源相关材料和技术的领导者 **

The long-term objective of this research program is to explore the unique properties of new perovskite-type functional materials and their integration into basic optoelectronic device architectures including solar cells and light-emitting diodes.******Perovskites materials offer new and remarkable functional properties (chemical, optical, optoelectronic etc.) and recent progress in their synthesis, manipulation and characterization at the nanoscale opens the way to new discoveries of functional materials and exploitation of their unique properties in several innovative applications. In the last 3 years, perovskites have yielded spectacular results and have generated a lot of attention world-wide as a promising material platform to develop high-performance solar cells produced at low costs. Here, we propose to explore two novel perovskite-type material systems: (1) multiferroic Bi2FeCrO6 oxide and (2) metal-halide perovskite MAGeI3/MA(Bi,In)3.******Three key research objectives are essential to succeed in this endeavour: (1) achieve a precise control of the synthesis process and improve the quality of the resulting material systems, (2) explore, understand and control their fundamental properties, and (3) optimize their properties for energy-related applications and integration in basic solar cell (using for example multiferroic Bi2FeCrO6, MAGeI3 and MA(In,Bi)I3) and light-emitting diode architectures (using in particular multiferroic Bi2FeCrO6). ******As such, the requested financial support will serve to create a challenging and exciting research environment for the training of young researchers, stimulate the advancement of fundamental knowledge, and generate major technological breakthroughs in optoelectronics. In addition to a great societal impact, this program will contribute significantly to position Canada as a leader in emerging energy-related materials and technologies**
