Indigenous Development of Semi-Automatic Equipments for Large Area Dye-Sensitized Solar Module Fabrication

Subcategory (under Clean Energy): Solar (PV)
Technology Readiness Level (TRL): TRL 6 - Full prototype at scale
Technology Outline (Process Description)

India was lacking expertise in indigenous manufacturing of 3rd generation photovoltaic technologies. Previously, those seek- ing such facilities had to rely on foreign technologies, resulting in costly imports. However, we have made remarkable strides in bridging this gap at CSIR-NIIST. We accomplished this feat by establishing India’s first indigenous module fabrication line for dye-sensitized solar modules in partnership with the industry. This remarkable achievement was commissioned in October 2018 and subsequently licensed to Elixir Technologies, based in Bangalore, for further commercialization in October 2019. Funding for this ground breaking project was generously provided by the Department of Science and Technology-Solar Ener- gy Research Initiative (DST-SERI), and it was also classified as a high-priority implementation initiative by the Prime Minister’s Office (PMO). The unique development achieved through this endeavour has been thoroughly evaluated and ranked TRL 7 by CSIR HQ, demonstrating the significant technological advancement it represents. Beyond establishing the pilot line facility, CSIR-NIIST has embarked on an interdisciplinary journey, harmonizing the disciplines of Chemistry, Physics, and Engineering nurturing a complete supply chain within the domain of DSCs. Moreover, we have dedicated ourselves to training numerous Ph.D. students and project fellows, thereby fortifying the knowledge base and expertise in this specialized area. Our com- mitment lies in delivering truly indigenous equipment and turnkey solutions for 3rd generation photovoltaic technologies, thereby revolutionizing the industry landscape in India.

Salient Features/Advantages

  • Successfully developed a range of equipments indigenously for the first time in the country which are essential for DSSC module fabrication in parallel interconnection partnering with Elixir Technologies, Bangalore thereby leading to import substitution and 60-70% cost reduction.
  • Process optimized for the fabrication of DSSC modules using parallel architecture and currently in the process of troubleshooting the engineering issues in the fabrication process
  • Showcased the feasibility of integration by coupling the DSSC modules with a temperature sensor making it self-powered, which worked solely with power generated by the DSSC module under LED/CFL light conditions.
  • Developed for the first time an integrated semi-automatic fabrication equipment which is capable of handling five functions together (Ag dispensing, UV dispensing, pick & place, UV curing and electrolyte filling).
  • New modified design for the screen printer’s furnaces for easy accessibility of larger substrates and to improve the efficiency in printing and annealing
  • Optimized a master plate of 2.5cm2 active area to be used for indoor light harvesting applications
  • Licensed the technology on a non-exclusive basis to industry for mass production of these equipment’s

Key Outcomes

  • We emphasize the Importance and the dire need for harvesting all forms of Light (Artificial/ Ambient/Diffused)
  • Catered to the resurgence of Dye Cells for Indoor Photovoltaic Applications
  • Indigenous manufacturing and Recycling/Re- use contributing towards circular economy
  • Development of an end-to-end decentralized ecosystem and supply chain development
  • Import substitution and Atmanirbharatha in light harvesting technologies for the future
