NanoGram, a company with a nanomaterial manufacturing process, has raised $32 million in venture funding which will be used to accelerate development of its silicon solar cells.
The Milipitas, Calif.-based company is one of many trying to engineer a leap in solar cell efficiency using materials technology.
The efficiency of traditional silicon solar cells--the most widely used material for cells--is progressing incrementally.
But many companies are pursuing are investing in manufacturing processes to both improve the efficiency of converting light to electricity and to bring down the cost of manufacturing. Start-up Nansolar last month began shipping its first cells … Read more
