Described are techniques for generating interactive presentations using three- dimensional (3D) computer models of photovoltaic (PV) power system components. In some embodiments, generating an interactive presentation involves creating a set of component models as 3D computer models of PV power system components. Further, an environment model is created as a 3D computer model of a real-world environment. The environment model can be combined with at least one component model from the set of component models to form an interactive presentation in which the environment model and the at least one component model are displayable as virtual objects on a display device. Various types of interactive presentations are described, including augmented reality, mixed reality, and virtual reality presentations.

Provided in the present invention is a method for preparing a perovskite thin film by means of ternary co-evaporation, comprising: using a ternary co-evaporation method to prepare lead iodide, cesium bromide and an organic passivator on a textured substrate so as to form a conformal mixed thin film, spin-coating an ammonium salt solution on the mixed thin film, and annealing same to form a perovskite absorption layer. The organic passivator can effectively passivate free lead iodide in the thin film before the thin film is formed, thus reducing internal defects of the thin film, and improving the quality of the thin film. The laminated solar cell obtained by means of the method has higher open-circuit voltage and photoelectric conversion efficiency and a lower attenuation rate.

The present invention relates to a method and a device for detecting defects in a photovoltaic panel by using an image of the photovoltaic panel. The photovoltaic panel defect detection method and device according to the present invention detect defects that cannot be detected in an EL image of the photovoltaic panel by using an artificial intelligence unit pre-trained with an optical image rather than the EL image, thereby classifying defects by type, and measure the size of defects so as to determine whether the panel is ultimately defective, and thus defect determination in a photovoltaic panel production process can be faster and more accurate such that process time is reduced and defect detection rate is increased, thereby enabling cost losses to be reduced.
