Identifying a threshold impurity level for organic solar cells.

Alan heeger solar panels.

Alan j heeger non fullerene acceptors have recently attracted tremendous interest due to their potential as alternatives to fullerene derivatives in bulk heterojunction organic solar cells. Professor alan heeger at the university of california santa barbara has silicon solar panels on his roof. While the windows use materials that behave similarly to ordinary solar panels the innovative ink substance is much thinner and much cheaper. Cowan sr leong wlin banerji n dennler g heeger aj.

Comes in different colors. Rooftop solar mandate in san francisco now official. Macdiarmid and hideki shirakawa for their discovery and development of conductive polymers they published their results on polyacetylene a conductive polymer in 1977. Alan heeger holds a flexible plastic solar cell made with a roll to roll printing tool.

Alan heeger was a founder of uniax which was acquired by dupont. The startup is called next and harnesses technology developed by nobel prize winning ucsb professor alan heeger. He won the nobel prize for chemistry in 2000 along with alan g. The transparent solar cells can generate power for air conditioning and even serve to screen from the sun s rays.

The liquid solar cell material can be printed from a roll to roll printing press much as newspaper is printed. Alan heeger winner of the 2000 nobel prize. Heeger says that the tandem architecture offers plenty of room for further improvement enough to eventually make plastic solar cells practical in rooftop solar panels. Nobel laureate alan heeger professor of physics at uc santa barbara worked with kwanghee lee of korea and a team of other scientists to create a new tandem organic solar cell with increased efficiency.

And being bendable can be placed along curved surfaces like the outer walls or windows of high rises. But he says for most people getting electricity straight from the sun isn t easy. The next generation of solar panels promises to be less conspicuous and expensive but the technology still needs to be made more efficient said prof. That s alan heeger a nobel chemistry laureate getting enthusiastic about new uses for thin flexible semi transparent solar cells he s developing using a liquid ink material.
