École Polytechnique

Ce cours d'introduction aux probabilités a la même contenu que le cours de tronc commun de première année de l'École polytechnique donné par Sylvie Méléard. Le cours introduit graduellement la notion de variable aléatoire et culmine avec la loi des grands nombres et le théorème de la limite centrale. [...]

Solar and wind offer clean and renewable ways to produce large amounts of electricity. They have boomed over the last few years, evolving from an eco-daydream to a major market and showing unprecedented growth rates. Yet, installing solar panels and wind turbines is by no means the end of [...]

The first MOOC “Photovoltaic solar energy” is a general presentation of the solar photovoltaics technologies in the global energetic context, without extensive details. In particular the description of the solar cell operation is restricted to the ideal case. In contrast this second MOOC allows a deep understanding of the [...]

Waves are everywhere. On water of course, but also in the air as you hear a plane, and under your feet during an earthquake certainly. Vibrations, too, are everywhere In your bike as you go over a bump, in you guitar as you play, [...]

Plastic electronics is a concept that emerged forty years ago, with the discovery of electrically conductive polymers. Ten years later, the first electronic devices using organic solids in place of the ubiquitous inorganic semiconductors were realised. The best achievement of plastic electronics is constituted by Organic Light-Emitting Diodes (OLEDs) [...]

The course is an introduction to the photovoltaic (PV) applications in the general mix energetic context dominated by climate warming mitigation. The various uses of solar energy are firstly presented before a short description of the principle of the direct solar photon conversion into electricity (PV). The various [...]
