I suspect it's a combination of three factors: First, there's a fundamental limit of the efficiency of solar cells. A solar cell is effectively a heat engine that uses the 6000K Sun as the heat source and the Earth's ~300K ambient temperature as the heat sink. Given that, the efficiency of a "perfect" solar cell tops out at around 95% for an infinite-...

If you are looking for theoretical prediction of candidate perovskite solar cell materials; I have come across several papers that couple high-throughput density functional theory calculations along with machine learning for new material prediction. I haven't seen any solar cell compound discovery theoretical work that eventually validated their predictions ...

To make a start in answering this question, here is a review on "Computational predictions of energy materials using DFT" by Jain et al. (2016). The bar for inclusion was: examples where theoretical prediction has led to the experimental discovery of a new material or exposed an important technological facet of a known material. Table 1 contains ...

To add to the previous answer: the new lead-free halide double perovskite $\ce{Cs_2InAgCl_6}$ was discovered by first-principles and then synthesized: G. Volonakis et al. $\ce{Cs_2InAgCl_6}$: A New Lead-Free Halide Double Perovskite with Direct Band Gap, J. Phys. Chem. Lett. 8, 772 (2017) https://pubs.acs.org/doi/10.1021/acs.jpclett.6b02682 I'm sure there ...
