Abstract: The present invention provides a drug virtual screening system for crystal complexes, and method of using the same, comprising a visualization subsystem, an evaluation tool box subsystem, an AI model management subsystem, a large-scale sampling subsystem, a virtual screening subsystem, and a data log storage subsystem. Starting with the known crystal complexes, a batch of candidate compounds that meet the requirements are recommended after going through the visualization subsystem, evaluation tool box subsystem, AI model management subsystem, large-scale sampling subsystem, and virtual screening system in turn. Based on this system, the generation of the compound library is organically combined with the subsequent virtual screening. Users only need to describe the action mode of the drug on the protein and the requirements for the drug to generate a batch of compounds that meet the expectations. The automated system reduces user intervention and improves the efficiency of research and development.

Abstract: PbI2 thin film crystallization control is prerequisite of high-quality perovskite layer for the sequentially solution-processed perovskite solar cells. According to the present invention, an efficient-and-simple method has been developed by adding halogen acid additive to improve perovskite thin-film quality and an efficiency of at least 15.2% is obtained. This approach improves coverage, uniformity and stability of pervoskite thin-film. In addition, a nanofiber scaffold is incorporated into the perovskite layer so as to reduce the amount of grain boundaries, thus substantially reducing electron recombination within these boundaries.
