Three P’s of research

16 03 2009

C. N. Yang, a famous physicist (Yang-Mills theory, Yang-Lee theory awarded Nobel Prize 1957, Yang-Baxter equation), said in 1986 that he believes there are three P’s in research: Perception, Persistence, and Power. All three factors are necessary, but perception and power are the more important. Persistence will come naturally with perception and power.

Yang always emphasized to his students the importance of intuition and that intuition can be sharpened. […] When one finds one’s intuition to contradict new phenomena, new principles, or new knowledge, that is when one has an opportunity to sharpen or improve one’s intuition. Understanding the origin of the contradiction would allow one greater intuition.

Dye solar cell from donuts and passion tea

13 03 2009

Blake Farrow, working in the group of Prashant Kamat, has created a video showing how to make a dye-sensitized solar cell. The nice point is that the basic elements of the DSC are extracted from food: they make the nanostructured titania calcinating a donut, and they make the sensitivization with purple tea leaves. The video also nicely shows that a solar cell can be created by chemical route with relatively simple steps, which is a serious key point for DSC industrialization.

The efficiency shouldn’t be high as this is a fun project but certainly it gives a photocurrent, about 40-50 microamps under sunlight filtered through the labwindow.

Report on organic solar cells (OPV) and hybrid organic/inorganic dye-sensitized solar cells (DSC)

11 03 2009

NanoMarkets, a leading industry analyst firm, announced 9 march 2009 the release of its report, “Organic Photovoltaic Materials Markets: 2009-2016”. The report projects that sales of materials for both “pure” organic solar cells (OPV) and hybrid organic/inorganic dye-sensitized solar cells (DSC), are expected to reach almost $600 million ($US) by 2016.
