Small Molecule OPV Donors

Small molecule organic photovoltaic (OPV) donors are crucial to the development of highly efficient organic solar cells. These molecules are designed to absorb sunlight and convert it into electrical energy through the photovoltaic process.

Features and Applications

Unlike their polymer counterparts, small molecule OPVs offer the advantage of well-defined structures leading to higher levels of control and more reproducible performance characteristics.
The structure of these molecules includes a conjugated system that facilitates the absorption of light and transport of charge carriers. These often consist of alternating donor and acceptor units to promote charge separation and transport.
The molecules are designed with solubilizing side chains to enhance processability.
Small molecule OPV donors are at the forefront of organic solar cell research, providing a pathway toward lightweight, flexible, and potentially more cost-effective photovoltaics. Due to this, they are applied to cutting-edge technologies such as all small molecule solar cells, hybrid solar cells and wearable electronics.

Our range includes donors for all-small-molecule, small molecule, and polymer solar cells.
