Exploring ways to improve the efficiency of organic solar cells

British and American scientists work together to find that the organic solar cells within a specific way to spin electrons , is expected to significantly improve the photoelectric conversion efficiency of organic solar cells, the latest technology can also be used to develop higher performance organic light-emitting diodes. Organic solar cells simulate the photosynthesis of plants work, its slim, lightweight and flexible, but also can be printed like a newspaper, compared with the current widely used silicon-based solar cells, the manufacturing process more quickly and at a lower cost. But its maximum photoelectric conversion rate of only 12%, not with the conversion efficiency of up to 20% to 25% so more commercial advantages comparable to silicon-based solar cells. Now, research conducted by scientists at the University of Cambridge and the University of Washington found that manipulating the electron spin mode in organic solar cells can significantly improve their performance, helping scientists to develop inexpensive and high-performance organic solar energy battery. Scientists have long been puzzled by the different behavior of electrons in organic solar cells, hoping to clarify why some electrons behave unexpectedly well, while others behave less than optimally. To this end, scientists at the Cavendish Laboratory at Cambridge University have developed a sensitive laser technology to track the behavior and interactions of electrons in organic solar cells. They were surprised to find that the "culprit" was the quantum nature of the electron-owned spin. Spin is a particle-owned property that is related to its angular momentum. Electrons have two spin modes: up or down. Through a process called "recombination," electrons in a solar cell lose the energy they possess and enter a completely empty state known as a "hole." Researchers have found that allowing electrons to spin in a particular way can stop the energy loss and increase the solar cell's current.

The researchers believe that this design concept helps scientists narrow the differences in conversion efficiency between organic solar cells and silicon-based solar cells and is also expected to make higher-performance organic light-emitting diodes. Organic light-emitting diodes are an emerging display technology used to make more efficient displays for use in cell phones and TVs.
