In times of fossil fuel shortage, increasing crude oil prices, as well as rejection of conventional energy sources (e.g. coal or nuclear power plants), sustainable energy forms become more and more the focus of attentions. Hydropower, wind power, geothermal power, or biomass processing are but a few of these sustainable resources.
Another important source for renewable energy is solar power. Photovoltaics and solar thermal collectors are most widely used.
Dye solar cells (DSCs) which are discussed in this application note are thin film cells. They are also called dye sensitized solar cells (DSSC) or Grätzel cells named after the Swiss chemist Michael Grätzel who was greatly involved in the development of new cell types.
From director Christopher Nolan (Inception, The Dark Knight trilogy) comes the story of a team of pioneers undertaking the most important mission in human history. Academy Award winner Matthew McConaughey (Dallas Buyer’s Club) stars as ex-pilot-turned-farmer Cooper, who must leave his family and a foundering Earth behind to lead an expedition traveling beyond this galaxy to discover whether mankind has a future among the stars. Also starring Academy Award winner Anne Hathaway (Les Miserables) and Academy Award nominee Jessica Chastain (Zero Dark Thirty).
