Domaine > Physique.

Descriptif

Eligibility/Pre- requisites 

Theoretical course on photovoltaics (Physics of Solar Cell Devices or equivalent) 

Learning outcomes 

his course makes the link between the fundamental physics of photovoltaic devices and the practical reality of selling PV-generated kWh. It is composed of two lectures (given by our industrial partners from Total) and a heavy laboratory component giving students the opportunity to fabricate and test photovoltaic devices in a research environment. After taking this course, the student should be able to:

  • Demonstrate experimental familiarity with critical elements of photovoltaic device fabrication or advanced material/device characterization

  • Identify, use and weight the physical parameters in a photovoltaic system and critical output metrics

  • Describe the industrial steps to produce photovoltaics modules

  • Identify usage of photovoltaics in appropriate applications

  • Have a global vision of the photovoltaics market, value chain and main players

  • Quantitatively evaluate a PV system costs and the PV electricity costs

  • Take into account safety

    Carry scientific messages on environmental impacts of photovoltaic
