It is understood that American scientists use a thin layer of plastic to gather solar energy on a solar cell made of gallium arsenide, which doubles the energy efficiency of the solar cell. This method not only reduces the use cost of solar cells, but also Of flexible solar cells can also show their talents in many fields.
At present, scientists plan to make larger plastic sheets, dotted with multiple smiling solar cell arrays. When the sun shines on the plastic sheet, it will be absorbed by a dye on the sheet that specifically captures the sunlight. Since this is a luminescent dye, it will release the absorbed light, but most of the released light is confined inside the plastic sheet, so these sunlight will bounce around inside the plastic until it reaches the inside of the solar cell . In view of the fact that this dye can only absorb part of the sunlight, in order to improve energy output, scientists have added a reflective material to the plastic sheet, which can introduce sunlight that the dye cannot absorb into the solar cell.
The research team has previously developed an innovative method that can make flexible and malleable solar cells that can adapt to irregular surfaces. The latest research method is compatible with this technology. The combination of these two methods to obtain low-cost and high-efficiency flexible solar cells is expected to find new uses.
The ability of the new type of dye and plastic film to collect sunlight has only increased by 10 times, while the Semprius company founded by the Rogers team has used another method to increase the ability to collect sunlight by 100 times. But the latter requires a very large concentrator and a tracking system to keep the battery facing the sun. This system may provide low-cost solar power for the grid, but it is not practical for solar helmets or laptop computers. In contrast, dye-coated plastics are thin and lightweight, and can absorb sunlight from different angles, eliminating the need for a tracking system.
