DYE SENSITIZED SOLAR CELLS KUPPUSWAMY KALYANASUNDARAM PDF

These nanoparticle DSSCs rely on trap-limited diffusion through the semiconductor nanoparticles for the electron transport. This limits the device efficiency since it is a slow transport mechanism. Recombination is more likely to occur at longer wavelengths of radiation. Photons striking the dye with enough energy to be absorbed create an excited state of the dye, from which an electron can be "injected" directly into the conduction band of the TiO2. From there it moves by diffusion as a result of an electron concentration gradient to the clear anode on top.

Life[ edit ] Dr. Kalyanasundaram completed B. He received his Ph. Following a two-year post-doctoral work at the Royal Institution of London, UK, he joined the teaching and research staff of the Chemistry Department of the Swiss Federal Institute of Technology where he remains till today. Kalyanasundaram has authored over research papers in international journals and 4 research monographs on his photochemistry research.

His research papers are well cited over 22, citations with a h-index 49, placing him amongst the top chemists of Switzerland and of chemists of Indian origin. Works related to Tamil language[ edit ] Created and is maintaining Tamil Electronic Library since TSCII is the only Indic language encoding to be formally included in the global inventory of font encoding standards for world languages. Founded Project Madurai initiative to bring ancient and modern Tamil literature into digital format.

Since its launch, Project Madurai has released etexts of over important Tamil literary works, big and small, covering a wide time span early Sangam Period classics to works of contemporary authors , all genre texts and anthologies in poetry, prose, drama , without any preference for any one religious texts include core works of Saivaite, Vaishnavaite, Christianity and Islam and of all regions works of Indian as well as Sri lankan authors.
