First developed in China in about the year A.D. 150, paper has many uses, the most common being for writing and printing upon. Indeed, the development and spread of civilization owes much to paper's use as writing material.
(Phys.org) —Rice University scientists have invented a novel cathode that may make cheap, flexible dye-sensitized solar cells practical.
The race is on to optimize solar energy's performance. More efficient silicon photovoltaic panels, dye-sensitized solar cells, concentrated cells and thermodynamic solar plants all pursue the same goal: to produce a maximum ...
One of the most promising types of solar cells has a few drawbacks. A scientist at Michigan Technological University may have overcome one of them.
