According to the Physicists Organization Network recently reported, researchers at the University of California, Santa Barbara proved that just by tuning the thickness of the active layer and embedding an optical interval between the active layer and the electrode of a small molecule organic solar cell, its efficiency can be increased by 50%, from 6.
02% to 8.
94%.
Organic solar cells and polymer-based solar cells are currently at the forefront of research in the world, but other organic materials, such as small molecules, have also proved promising
.
Although small molecule organic solar cells are now less efficient than polymer solar cells, they are generally easy to manufacture and easier to improve
.
The researchers explained in the paper that small molecule organic solar cells have several advantages over organic polymer solar cells: relatively simple synthesis, high charge carrier mobility, particles of the same size (monodispersity) and better reproducibility
.
However, small molecule solar cells have achieved the highest efficiency to date at around 8%, somewhat lagging behind the best polymer devices
.
In some simple demonstrations, the research team led by Professor Allan tuned the thickness of the movable layer of a small molecule solar cell, embedding a zinc oxide optical interval between the movable layer and the metal electrode to be able to capture more light and improve light absorption
.
The optical spacer inserted into the active layer is in a more advantageous position
in the optical electric field within the battery.
