AI Customer ServiceIn this current study, we presented a state-of-the-art self-protected thin film c-Si solar cell against reverse currents by introducing a heavily doped layer sandwiched between the n-type emitter and the p-type base of the device. The proposed structure showed a significant performance under different biasing conditions.
To protect the solar cell against the reverse current, we introduce a novel design of a self-protected thin-film crystalline silicon (c-Si) solar cell using TCAD simulation. The proposed device achieves two distinct functions where it acts as a regular solar cell at forward bias while it performs as a backward diode upon reverse biasing.
In a recent issue of Joule, Xu et al. demonstrated tha,t unlike single-junction perovskite solar cells, perovskite/silicon tandem cells (PSTCs) can withstand even a negative bias of −15V for >12 h without any signs of degradation by tackling the issues above at its source—limit the reverse leakage current ( I r e v ).
A solar cell can become reverse biased (i.e., can operate at a negative voltage) when it produces significantly less current than the other cells that it is connected in series with, for example, in the solar modules.
Due to these challenges in obtaining certain fundamental properties, silicon-based heterojunction solar cells are mainly characterized by several indirect measurements in combination with device simulations to obtain some target parameters that can reflect the properties of certain layers or interfaces.
Since the copper indium gallium selenide (CIGS) solar cells also have a relatively low V bd, they most likely cannot enable high resilience to perovskite/CIGS tandem devices against reverse bias, although currently no experimental evidence supports this claim according to our knowledge.
