The Research team of New York University, Tandon School of Engineering, develops a phenomenal means creating solar cells. These organic solar cells are resistant to air, light, and water. During the research, they removed the material from the device instead of adding any material to it. This is attained by sticking an adhesive tape to the device to strip off the electron receiving molecules.
Degeneration of a device happens due to oxidation of molecule derivatives. However, by removing PCBM from uncovered film surface minimizes the chances of oxidation with sources such as oxygen and water.
Organic Solar Cells Vs Traditional Silicon Cells
According to the study, mass production of solar cells is possible using coil to coil processing method. There are several advantages of organic solar cells over traditional silicone cells. Raw materials needed for production of solar cells can be found easily in nature. Organic solar cells are semi -transparent, thus minimally meddlesome as compared to traditional silicon cells. Solar cells can be affixed on windows, screens, and are apt for mobile devices. They have high elasticity and can be stretched to a large extent. These are known to be very light weight.
Organic solar cells are immune to sunlight, water, and oxygen unlike traditional silicon cells. They can last for a longer time under exposure to moisture, without affecting the efficiency. Moreover, removal of electron receivers through adhesive stripping technique can result in highly durable solar cells. The production cost of these solar cells are high due to the state of the art treatment in enveloping the cells. However, their resistance to water makes them impressive as these can be beneficial in products like solar cell swimming watches.
