Synthesis of high quality zinc-blende CdSe nanocrystals and their application in hybrid solar cells
Summary
This article discusses the synthesis and application of high quality zinc-blende CdSe nanocrystals in hybrid solar cells. Through manipulation of the chain-length and concentration of cadmium precursors and the concentration of oleic acid, the morphology and fluorescent properties of the nanocrystals were adjusted. The hybrid solar cells based on the obtained spherical CdSe nanocrystals and either Poly(2-methoxy-5-(2'-ethylhexoxy)-p-phenylenevinylene) (MEH-PPV) or poly(3-hexylthiophene) (P3HT) as a donor showed energy conversion efficiencies of up to 1.08%. This research suggests that hybrid solar cells based on CdSe nanocrystals may be a viable alternative for future production technologies.

AI Discussion
Me: It's about the synthesis of high quality zinc-blende CdSe nanocrystals and their application in hybrid solar cells. It discusses the implications of using these nanocrystals and the potential to develop new production technologies for hybrid solar cells.
Friend: That sounds really fascinating. What are the implications of using these nanocrystals?
Me: Well, the article mentions that the use of these nanocrystals could lead to an energy conversion efficiency three times higher than that reported before for spherical CdSe NCs/conjugated polymer hybrid solar cells. Additionally, when poly(3-hexylthiophene) is used as the donor phase instead of MEH-PPV, the energy conversion efficiency increases up to 1.08%. So these nanocrystals could potentially revolutionize hybrid solar cell production and make them more efficient and cost-effective.
