摘      要：With the ubiquitous acceptance of PVs, the number of devices manufactured annually is following an exponential trend. Yet, the manufacturing process of important brands of thin-film solar cells involves a tedious and expensive step of laser scribing. The time-consuming and technologically involved laser scribing method remains widely used to contact the device electrodes. This work examines an alternative method (threshold switching phenomenon) to create an enduring conductive path in cadmium telluride (CdTe) PV, which eliminates the pitfalls in conventional scribing technology. The samples undergone threshold switching show a promising sign of the conductive path compared to the control samples. This method could potentially lead to the manufacturing technology saving time, money, and raw materials along with the added reliability and efficiency. © 2023, CC BY.
