Brighter together: designing sustainable technologies to create electronic devices
An article about an Aalto research project focusing on light-emitting electrochemical cells has been published in Chemical Science. The research was conducted by the Photoactive Organic Materials group in collaboration with . The research touches our everyday lives, as it鈥檚 closely related to electronic devices we all use in our day to day lives.
The research project has a significant importance, as doctoral researcher Alba Sanz Velasco explains when talking about the context of the study: 鈥淲e are currently living in a digital era, surrounded by electronic devices such as smartphones, tablets, or TVs. However, materials used for developing this technology, in general, fall short of meeting environmental sustainability standards. For example, Organic Light Emitting Diodes (OLEDs) are broadly used to create light in display panels, but the short lifetimes of their materials significantly limit their long-term use. Therefore, in this research we have focused on improving the lifespan by designing a new technology based on light-emitting cells (LECs) in which light is created by a more sustainable material. Moreover, LECs comes with lower manufacturing costs compared to OLEDs. Our research results emphasize the potential of this technology as a promising and innovative substitute to current options.鈥
The weakness of current broadly used technology acted as a catalyst for the research. The researchers aimed to create a more sustainable way of fulfilling the needs of humankind. 鈥淪ustainability surrounding OLEDs for lighting applications concern not only from environmental factors but also disadvantages associated to their long-term applicability. The main drawback of this technology is the short lifespan of the material caused by an inner phenomenon. In essence, our research aimed at developing materials for lighting applications with the broader goal of creating sustainable technologies that balance human needs with environmental preservation鈥, Sanz Velasco further explains.
