"Small molecule" organic solar cell efficiency will increase by 50%

American scientists have found that the energy efficiency of "small molecule" organic solar cells can be increased by 50% through simple modifications. This discovery is expected to help the solar cell industry to develop new ideas. In a new study, researchers at the University of California, Los Angeles, discovered in a new study that only by adjusting the thickness of the active layer and between the active layer and the electrode, scientists in the United States discovered that through simple modifications, the " Small molecule "organic solar cell energy efficiency can be increased by 50%. This discovery is expected to help the solar cell industry to develop new ideas. In a new study, researchers at the University of California, Los Angeles, found that just by adjusting the thickness of the active layer and inserting an optical spacer between the active layer and the electrode, according to the Physiologist Network today reported in a new study The energy efficiency of a small molecule organic solar cell increased from 6.02% to 8.94%.

The experimental results show that small molecule organic solar cells have the potential to compete with current polymer batteries. It is understood that the current polymer battery energy efficiency close to 10%. The report also said that in the field of organic solar cells, polymer-based equipment is currently the most high-end. But other organic materials such as "small molecules" are also considered promising. Although "small molecule" organic solar cells are currently less energy efficient than polymer solar cells, they are generally easier to make and have higher efficiency.

In addition, scientists have shown that these discoveries still have potentially huge room for improvement.
