iit scientists create low-cost solar cells using jamun
Researchers used natural pigments found in jamun as a cheap light-sensitivity agent for dye-sensitive solar cells (DSSCs)
Or Gratzel cells.
The thin film solar cell of Gratzel cells is made of porous titanium dioxide (TiO2)
Coating the photopositive pole, the dye molecular layer absorbing the sunlight, the electrolyte of the regenerated dye and the cathode.
These parts form sandwiches-
Similar to the structure of dye molecules or photosensitive substances, the ability to absorb visible light plays a key role.
\"Jamun\'s dark and IIT campus\'s massive jamun tree clicks on the idea that it can be useful in typical dye-sensitive solar cells (DSSC)
Assistant professor of Indian Institute of Technology and chief researcher Soumitra Satapathi (IIT)
\"Said Roki of utalakhand.
The researchers used ethanol to extract dyes from jamun.
They also use fresh plums and blackcurrant, as well as mixed berry juices that contain pigments that give jamun a unique color.
Then centrifuge the mixture and pour it out.
The extracted colored pigment, called Huaqing pigment, is used as a sensitivity agent.
\"Natural pigments are very economical compared to ordinary ru --
Based on pigments and scientists are optimizing to improve efficiency . \"
Satapathi is also a visiting professor at the University of Massachusetts at Lowell. S.
\"There is growing pressure on fossil fuels, and concerns about global warming have prompted people to keep looking for alternative energy sources,\" he said . \"
Satapathi\'s uncertainty about the speed of new dams or nuclear power plants means a strong reliance on solar energy
India has great potential and the same ambitions
Fulfilling the country\'s commitment to increase its share of non-debt by 40
By 2030, fossil fuel capacity in the power industry will increase, the researchers said.
\"In principle, we have a huge social demand for renewable energy, especially solar energy.
For a long time, our lab has been actively engaged in low-cost, high-efficiency solar cell production . \"Satapathi.
The team of researchers, including nipaun Sawhney and anubragraghav, are very optimistic that the process can be easily replicated for mass production of solar cells.
The simplicity and cost-effectiveness of the entire manufacturing process, the wide supply of fruits and juices, and the easy extraction of floral pigment dyes make them new cheap candidates for solar cell applications, the researchers said
The study was published in the Journal of photovoltaic.
