Concentrated Solar Startup Sets a New Efficiency Record

Semprius, a startup that makes miniscule solar cells capable of capturing concentrated sunlight without costly cooling systems, announced this week that it had made the world's most efficient solar panel.

The company's solar panels use tiny solar cells made of gallium arsenide—the record-breaking solar module contains hundreds of such solar cells, each about the width of a line drawn by a ball-point pen, arranged under lenses that concentrate sunlight 1,100 times.

Gallium arsenide is far better at absorbing sunlight than silicon, the material used in most solar cells, but it's also more expensive. Furthermore, although concentrated solar modules use less semiconducting material, they usually require expensive optics, cooling systems, and tracking systems to keep them aimed at the sun. Semprius's microscaled solar cells are inherently much better at dissipating heat, making them cheaper.

Semprius's modules have another advantage: whereas a silicon solar cell only efficiently absorbs a narrow band of sunlight, the solar cells in this module are made of three layers of gallium arsenide, each modified to convert a different part of the solar spectrum into electricity.

Do you think solar panel roadways linked across the country could reverse the effects of global climate change

My idea to solve the problems of oil
My idea is to create an electrical system placed on our nations roads as an interconnected network of highly durable plastic solar panel.


The idea certainly makes me think ... I love questions that make me think: "Why did not I think? It makes sense! "I would answer some questions and concerns that others respond to light.
