In cooperation with the three universities, Massachusetts Amherst University, Stanford University, and Dresden University jointly developed a new type of nanostructure that can increase the efficiency of organic solar energy from 2.2% to 2.9%, an increase of 32%.
According to reports, solar cells use two different types of semiconductors, namely P-type and N-type, which make contact with each other to form a so-called "PN junction." This is an important part of solar cells because it generates electric fields, making light Can be transformed into current.
After decades of experimentation, scientists have discovered that the ideal "PN junction" structure is a vertical nano-pillar "nanograss" that can capture light very efficiently and has been implemented on inorganic solar cells, but There are challenges on elusive organic solar cells.
Now, the research team has invented a new simple, flexible technology that can produce this “nano grassâ€. They put semiconductor raw materials and graphene primers in a vacuum temperature gradient furnace. The initial low temperature can form an ultra-thin film first, and then as the temperature rises, the semiconductor compound pushes up like a coin, one by one. "Nanograss" was formed.
They said that this process is more flexible, in addition to graphene, zinc oxide, copper iodide and other primer is also possible.
The researchers tested and found that by adopting this structure, the efficiency of organic solar energy increased from 2.2% to 2.9%, an increase of 32%.
