A team of scientists from China and Sweden have created an organic solar cell which is optimized to transform the indoor lights in energy. The electricity being produced is low. However, it is sufficient to run several products brought online by Internet of Things.
With the advent of Internet of Things, the need to several online products, both in homes and public space is increased. Many of them would be a variety of sensors so as to measure and detect temperature, particle concentration, moisture, and several other parameters. Resultantly, the demand regarding affordable and small renewable source of energy is on the rise, to decrease the requirement of expensive and often battery replacements.
Owing to these scenarios, the demand for organic solar batteries is increasing rapidly. They are flexible, easy to manufacture due to increased surfaces in printing press, and cost-effective in terms of manufacturing. Another key advantage of these solar cells responsible is the layer that is responsible for light absorption, comprise mix of acceptor as well as donor materials. This provides the sufficient flexibility in fine tuning the organic solar cells. It helps them optimizing with various spectra for different wavelengths.
Unique Combination of Donors and Acceptor Materials to Act as a New Innovation
Researchers led by Feng Gao, from Linköping, Sweden, and Jianhui Hou, from Beijing, China, have created a novel combination of acceptor and donor materials that precisely determined the composition, which is to be utilized in solar cell as an active layer. This combination exactly absorbs the light wavelengths which is present in the living rooms, supermarket, libraries, etc.
The teams have said that they are confident about the efficiency of the organic solar cells in future. They could be well utilized for usage with ambient lighting applications, owing to huge room for material optimization required in the process. The discovery is likely to be a promising one in terms of indoor solar cells.
