в€‚ P V, therefore, complements the existing offer of AD-based solvers and, relying on the composability of these tools, potentially enables end-to-end differentiability of more advanced multiphysics simulations where the DD model is coupled with full Maxwell equations. Based on these tools, several AD-enhanced simulators have been released, including for molecular dynamics, , fluid dynamics, kinetics, optics and general purpose solvers. Notable examples include JAX, where AD is based on tracing, and Zygote, built on source-to-source transformation. The rise of this line of research has been enabled by the development of growing AD-tools. By computing derivatives with AD, we avoid numerical and scaling issues associated with the finite-difference technique, while adding complexity comparable to that of the original problem. Thus, this new computational tool enables extensive, efficient materials optimization for PV cells, and can be used in conjunction with standard optimization methods, or machine learning algorithms.

в€‚ P V is able to compute not only the efficiency of the solar cell but also its derivative with respect to any material property set by the user. In this work we present в€‚ P V, a 1D simulation tool for PV cells which solves the drift-diffusion equations using the JAX automatic differentiation (AD) package. This is in part due to the unavailability of derivatives, which are key to efficient high-dimensional optimization. Although solar cell modelling is quite well developed, the optimization of solar cells is much more challenging, particularly in the case of optimizing many design variables jointly. These computational tools also allow the study of important physical phenomena such as the effects of grain boundaries and defects, that impact the performance of solar cells. Such simulators have brought significant advances in studying solar cells, and have been applied to common systems including CdS-CdTe and perovskite cells. A number of packages have been extensively developed, and are freely available, such as PC-1D, SCAPS, wxAMPS or SESAME.
