Researchers have created a device called 'shadow effect power generator' that uses the contrast in lighting between illuminated and shadowed areas to generate electricity. This novel concept opens up new approaches to take advantage of indoor lighting conditions to power electronics. Shadows are often associated with darkness and uncertainty. Now, researchers at the National University of Singapore (NUS) are putting a positive spin on shadows by demonstrating a way to harness this common but often overlooked optical effect to generate electricity. This novel concept opens up new approaches to generating green energy under indoor lighting conditions to power electronics. A team from the NUS Department of Materials Science and Engineering,
As well as the NUS Department of Physics, created a device called a shadow effect energy generator which uses the contrast in lighting between illuminated and shaded areas to generate electricity. Shadows are omnipresent, and we often take them for granted. In conventional Phone Number List photovoltaic or optoelectronic applications where a constant light source is used to power devices , the presence of shadows is undesirable as it degrades the performance of the devices. In this work, we capitalize on the illumination contrast caused by shadows as an indirect source of energy. The contrast in illumination induces a voltage difference between the shadowed and illuminated sections, resulting in an electric current.
This novel concept of harvesting energy in the presence of shadows is unprecedented,” explained research team leader Assistant Professor Tan Swee Ching, who is from the Department of Materials Science and Engineering at NUS. Mobile electronic devices such as smartphones, smart glasses and electronic watches require an efficient and continuous power supply. As these devices are used both indoors and outdoors, portable power sources that could take advantage of ambient light can potentially improve the versatility of these devices. While commercially available solar cells can play this role in an outdoor environment, their energy collection efficiency decreases significantly in indoor conditions where shadows are persistent.
