Cheaper Solar Cells via New Metallurgic Route , Using African Sand

GiraSolar B.V. (www.girasolar.nl) aims to find a completely new route from sand to solar cell, which is cheap and clean. Current chemical routes have been developed for silicon chip technology. But this route appears unnecessarily cumbersome and expensive for making silicon which will be used for solar cells. The solar cell market is becoming mature enough to merit a separate silicon production route. The idea is to use African sand as source, given the properties this sand has. This project follows a highly successful start up project in 2006 and may lead to a major breakthrough not only in silicon processing and cheap photovoltaic energy but in development of African sources and recourses as well. GiraSolar B.V. is a company in sales and future production of solar cells.

Main Tasks:

  • Investigate the best sand sources and socio-economical environments in Africa.
  • Investigate current routes and new electrochemical routes from sand to metallurgical silicon with screening of literature and running of feasibility experiments.
  • Investigate current silicon purification processes relative to new electrochemical ones with screening of literature and running of feasibility experiments.
  • Investigate current cell manufacturing relative to the new direct electrochemical deposition approach with screening of literature and running of feasibility experiments.
  • Investigate possible business scenario?s and risks with market entry strategies

Expertise - A team is sought with the following backgrounds:

  • 1-2 students in physics, chemical engineering, materials (3ME, TNW, L&R)
  • 1-2 students in civil Engineering or geo Sciences (CiTG)
  • 1-2 students in entrepreneurship, marketing, management, product development (TBM, IO)

Main Results:

  • Report describing:
  • Optimum sources
  • Electrochemical reduction (im)possibilities
  • Optimum purification routes
  • (Im)possible routes for direct electrochemical deposition cell manufacturing
  • Samples of silicon
  • Small solar cells

Upon good results, some paid full time or freelance work may be offered as job or as project for your own techno start up company. Moreover, a trip to Africa may be part of this project.
