Recently, the State Intellectual Property Office announced a number of photovoltaic invention patents for Trina Solar, including two patents on perovskite and heterojunction technology. According to
the data, the inventors of the patent named "Photovoltaic Device, Its Preparation Method and Preparation Device" are Gao Jifan and Xu Rui, and the application publication number is CN117241637A. The patent application time is August 14.
The invention provides a photovoltaic device, a preparation method and a preparation device thereof, wherein the photovoltaic device comprises a perovskite layer, and the preparation method of the perovskite layer comprises the following steps of: dispersing a perovskite precursor solution on a substrate to form a plurality of liquid droplets arranged at intervals; Droplets on the substrate are diffused and interconnected to form a perovskite solution layer , and the perovskite solution layer is annealed to prepare the perovskite layer.
Another patent is " Heterojunction Solar Cell and Its Manufacturing Method, Photovoltaic Module and Photovoltaic System ", the application publication number is CN117238979A, and the patent application date is September 5. The abstract of the
patent shows that the patent relates to the technical field of solar cells, in particular to a heterojunction solar cell and a manufacturing method thereof, a photovoltaic module and a photovoltaic system. According to the embodiment of the invention, the backlight surface is set to be the polished surface, and the conductive transition layer and the metal layer are adopted to replace the transparent conductive layer in the related technology, so that the cost is reduced, the short-circuit current can be integrally improved, and the photoelectric conversion efficiency of the solar cell is further improved.
Before that, Trina Solar has won many patents in perovskite and heterojunction technology.
On November 24, Trina Solar's " Heterojunction Back Contact Battery and Its Applicable Battery Components " was published as CN117117023a, and the application time was October 8. The
patent abstract shows that the invention provides a heterojunction back contact battery and a battery component applicable to the heterojunction back contact battery.
Then on December 5 , Trina Solar published a patent entitled " Photovoltaic Devices and Their Preparation Methods, Photovoltaic Modules and Photovoltaic Systems " with the publication number CN117177595a. The application date is September 5, 2023.
The patent abstract shows that the application relates to the technical field of photovoltaic power generation , in particular to a photoelectric device and a preparation method thereof, a photovoltaic module and a photovoltaic system, Which is used for solving the problems of poor wettability of the perovskite material on the SAM, poor bonding performance between the SAM and a substrate layer and the like in the related technology.
