Description

Technical Field

[0001] This utility model relates to the field of photovoltaic cell testing, and specifically to a cell testing device. Background Technology

[0002] IBC (Interdigitated Back Contact) is a battery with interdigitated back contact. This type of battery designs all the positive and negative electrodes, as well as related grid lines and electrodes, on the back of the cell, resulting in a more aesthetically pleasing front side and higher conversion efficiency by utilizing the light-blocking area lost due to grid lines. Currently, research on IV testing systems based on back contact batteries focuses on BC battery processes with the same pattern, which has poor compatibility with different BC battery printing patterns and other mainstream technologies in the industry such as Topcon and OBB processes.
