What are the main stages of development of dye-sensitized solar cells?

I'm honored to answer your question!

Dye-sensitized solar cells are a type of functional solar battery that uses a metal oxide semiconductor as a carrier and chemically adsorbs an organic dye that absorbs visible light. “Nano” refers to the microscopic size of the battery’s metal oxide semiconductor. Metal oxide semiconductor particles of tens of nanometers (usually TiO2) have good light transmission and capture effects. Simply put, its working principle is to use organic dyes as antennas to absorb part of the visible light. The high-energy electrons excited by the dyes are transmitted to the external circuit via metal oxide semiconductors, thereby generating current. The photoelectric conversion efficiency of the dye-sensitized solar cells was 71%.. In 1993, the world record for photoelectric conversion efficiency of dye-sensitized solar cells was 117%. In 2011, the world record for photoelectric conversion efficiency of dye-sensitized solar cells was 71%. 13%

I hope this can help you!

Books on pure nanomaterials are castles in the air

First of all, the most important thing is chemical knowledge. You need to know the four basics of chemistry, and polymers are based on all four. basics. , which is the most basic.

Then there is structural chemistry. If you don't know the four basics, you won't know the structure. ThisOnly after knowing structural chemistry can you know how nanoparticles grow. knowledge of materials science

Read the basics of materials science, materials chemistry, materials physics, nanomaterials and composite materials, so you know what a crystal. Many nanoparticles are crystals, which you should know about.

Then there are more advanced courses, which are usually postgraduate courses. When it comes to research, you have to understand the details. The most basic is instrumental analysis. You know how to analyze something. you can read other people's articles. You can understand a little. Of course, you should focus on reading a certain number of books based on your own research direction. The basic books involve a lot of general and quantum stuff. mechanics, large quantities, chistructural crumb and crystal chemistry Yes. If you're doing synthesis, you need to look at advanced organic and inorganic materials. You need to review physical chemistry. You have to relearn polymer physics and polymer chemistry. read about 500 corresponding papers and carefully read 200 articles, otherwise you would not know the trends and gaps in research. As for applications, you have to figure it out yourself, which is usually easier than the above, but you need to pay attention to national and international standards.

When it comes to electronics, there are very few books. Since it is nanotechnology and is new, there is a lot of overlap. Most current applications concern nanoelectronic components, i.e. nanoparticles, nanowires and nanotubes. For manufactured components, it is best to readmacro-electronic books and then read the corresponding foreign literature. Some organic optoelectronic materials are highly analyzed. If you read books about optoelectronic materials, you will know about transitions, orbits, energy levels and electromagnetic curves. You will generally know the current state of research at home and abroad.
