Photovoltaic Research in IIT Delhi
Mon, 30/09/2013 - 11:00
Location:
Speaker:
Prof Viresh Dutta
Affiliation:
Indian Institute of Technology, New Delhi
Synopsis:
The research on Photovoltaics (PV) has been going on in IIT Delhi since early 70s. The earlier work had been on crystalline Si solar cells and Thin Film Solar Cells. The main emphasis has been to develop inexpensive deposition techniques for thin layers required for the PV devices. The solution growth (now called the Chemical Bath Deposition) of semiconductor layers and spray deposition are some of the examples of such techniques.
The presentation will cover different areas of PV device research currently going on in the institute. These include: (i) Spray Deposition of large area TCO coatings , (ii) Continuous Spray Pyrolysis (CoSP) technique for nanoparticle and nanostructure fabrication , (iii) Spray deposition of Polymer layers for organic solar cells , and (iv) IIT Delhi DSSC fabrication technology.
PV systems have also been established in IIT. A 25 kWP PV generator is installed for supplying PV electricity to the utility grid in Solar First Mode with a virtual grid. A 5 kWP PV generator is established as part of PV / Fuel Cell Hybrid system with 1 kW Fuel Cell, Electrolyser for hydrogen generation and Metal Hydride for hydrogen storage. 1 MWP roof top PV generation in the institute is also under processing.
India’s need for solar energy is well understood and SPV applications are being widely promoted. The work done in IIT Delhi is an effort to develop the PV technologies in the country and to make the PV electricity an important component of the electricity generation technology mix.
