Metrotvnews.com, Surabaya: photosynthetic bacteria could replace silicon as the raw material of solar cells (solar cells) are needed in the development of solar power plants (SPP).
"These bacteria capture energy from the sun to photosynthesize while ago through a certain process of generating electricity," said researchers from the University of Ma Chung Monika Prihastyanti on the sidelines of the exhibition "Institutional Strengthening of seed science and technology centers throughout Indonesia" at Airlangga University in Surabaya, Friday (13 / 6/2014).
The electricity generated by a particular method in which the pigments of bacteria that are unstable first processed for reinforced structure using polymer materials, he said.
"We were given a glass plate to prepare nano particles of Titanium Oxide (TiO2) to be able to absorb electrons. Then the plate was dipped in liquid pigment, the added polymer and carbon materials. Result is a kind of solar cells," he said.
He has been much research into the development of solar cell in Indonesia, but the use of new materials bacterial Ma Chung University, Malang. In the U.S., he said, has developed a solar cell is derived from spinach plants with the same principle of using photosynthetic capabilities.
"But bacteria have an advantage over plants, the electromagnetic wave spectrum is longer so that it can better absorb solar energy," he said.
