LONGi Green Energy has applied for a patent for a battery and photovoltaic modules aimed at improving battery efficiency. According to information from the National Intellectual Property Administration, the patent, titled “A Type of Battery and Photovoltaic Module,” was filed on November 2024 and has the publication number CN119815989A.
The patent summary indicates that the implementation provides a battery and photovoltaic module. The battery consists of a substrate featuring a first surface and a second surface, with the first surface containing multiple light-trapping holes. It also includes a first and a second grid line, which are arranged alternately on the substrate. The first grid line overlaps with at least one of the light-trapping holes in the thickness direction, while the second grid line does not overlap with the light-trapping holes.
In this implementation, the first and second grid lines facilitate a shorter and more consistent collection distance for charge carriers, thus avoiding the local electric fields created by the accumulation of carriers. This leads to improved battery efficiency. Furthermore, this design helps prevent stress concentration within the battery, thus reducing the rate of battery fragmentation.
According to data from Tianyancha, LONGi Green Energy Technology Co., Ltd., established in 2000 and located in Xi’an, primarily engages in wholesale operations. The company’s registered capital stands at 757,804.4598 million RMB. As per big data analysis from Tianyancha, LONGi Green Energy has invested in 35 companies, participated in 322 bidding projects, and possesses 201 trademark records and 1,897 patent records. Additionally, the company holds 54 administrative licenses.
