What is it about?
This study demonstrates the implementation of novel self-assembled organic materials in silicon heterojunction solar cells. We investigated the charge transport properties of these organic molecule-modified contacts and examined their performance in solar cells as dopant-free charge-selective contacts for silicon heterojunction solar cells.

Why is it important?
The use of novel self-assembled organic materials in silicon solar cells using a low-cost and vacuum-free deposition technique is of interest. We showcase the fabrication of thermally stable self-assembled organic molecule-modified silicon heterojunction solar cells. This work also provides insight into the interfacial engineering of electron-selective contacts via self-assembled organic molecules.
Perspectives
As the cost of photovoltaic products continues to decrease in the coming decades, cost-effective manufacturing methods will become increasingly crucial. Instead of high-budget vacuum systems, low-cost deposition methods will become prominent. In addition, the use of self-assembled organic materials in silicon-perovskite tandem solar cells has gained attention, achieving record solar cell efficiencies. With the increasing popularity of self-assembled organic molecules, the investigation of new materials in solar cell research offers new perspectives and becomes even more significant.
