Solar Energy and Photovoltaics Videos

This educational video explains how solar photovoltaics work, how they create electricity from solar energy, and how photovoltaics actually produce electricity. It them goes on to how the system produces electricity for domestic consumption and how excess electricity can be sold back to the grid. Also shown are the various different types of solar panels that can be used in an installation.

This video shows how Washington is becoming a green state. They feel that they are leading the clean technology revolution both with the development of technologies and initiatives, as well as their commitment to reducing energy consumption, reducing their carbon footprint and developing alternative energy sources. The commitment extends from government, right through to industry, where they are looking to develop technologies for sale to the rest of the world.

Bluglass was originally established to commercialise a low cost technique for producing LEDs. The technology involves the Remote Plasma Chemical Vapour Deposion (RPCVD) process for producing gallium nitride films. This low temperature process can also be applied to the production of photovoltaics, where their process can be used to produce films with a higher indium content, wich can effectively boost the efficiency of the solar cells.
