Thin-Film PV laser scribing test system

Equipment Function: Using high-precision lasers, a large-area solar cell substrate is divided into multiple sub-cells and connected in series, thereby improving overall voltage and power output. The equipment comprises four processes: P1 (scribing the bottom transparent conductive layer), P2 (windowing the functional layer), P3 (isolating the back electrode layer), and P4 (edge ??cleaning).

Product Description

Equipment Function: Using high-precision laser processing, the system divides large-area cell substrates into multiple sub-cells and realizes internal series interconnection, thereby increasing overall voltage and power output. The system integrates four process steps: P1 (bottom transparent conductive layer scribing), P2 (functional layer opening), P3 (back electrode isolation), and P4 (edge deletion).

Applications:?Perovskite solar cells, OPV solar cells, CdTe solar cells, and other thin-film solar cells.?
