A Theoretical study of charge transport properties in perovskite analogues for high performance solar cells. — •Prerna Prerna1,2 and Harald Oberhofer1,2 — 1University of Bayreuth — 2Bavarian Center for Battery Technology, Bayreuth, Germany
Perovskite materials have emerged as promising candidates in solar cell technology, offering exceptional efficiency and affordability. Their remarkable performance, surpassing that of conventional inorganic materials, has placed them at the forefront of next-generation solar cell research, attracting significant attention from both academic and industry.
To harness their potential, we are investigating their charge transport properties using first-principles calculations (DFT) within the band transport regime. Our focus includes the calculation of carrier mobility, scattering rates and relaxation time through a detailed analysis of effective mass, deformation potential, and elastic properties. Our studies also incorporate the effects of structural deformations, aiming to align theoretical predictions with experimental results, providing deeper insights into the transport mechanisms in perovskites.
Furthermore, we are exploring the anisotropic nature of perovskites to understand directional dependencies in their electronic and mechanical properties. This anisotropy analysis is crucial for optimizing their performance and tailoring their application in advanced solar technologies. Together, these studies offer a comprehensive approach to enhancing the functionality of perovskites for cutting-edge solar energy solutions.
