A New Evaluation Method For The Stability Of Cathode Materials For The Third Generation Solar Cells

- Jan 22, 2017 -

With the increasing demand for energy, energy crisis and environmental pollution have become the two major problems facing the world today. In front of the huge energy gap, dye-sensitized solar cells because of its high photoelectric conversion efficiency, low cost, environment friendly and transparent, logical to become the research focus of world attention. Compared with the first generation silicon based solar cells and the second generation thin film solar cells, as the third generation of solar cells, dye-sensitized solar cells, because of its unique advantages, has attracted the attention of academia and industry. At present, the efficiency level of liquid dye sensitized solar cells is up to 14.3%, which is close to the basic level of commercial application of silicon-based solar cells.          

However, the photoelectric conversion efficiency and device stability have become the bottleneck of industrial application of the third generation dye-sensitized solar cells. As an important component of the solar cell, the cathode catalytic material is of great significance. However, the research on the stability of the device has not attracted enough attention of researchers, so far there is no academic papers for evaluating stability of cathode material in dye-sensitized solar cells have reported.          

Xi'an University Of Architecture And Technology professor Winsnin Artaud, Finland university professor Lund Peter and the German Fraunhof Institute for solar energy systems Andreas Dr. Hinsch from different angles for readers and researchers to provide a systematic evaluation of the cathode material stability strategy.          

Professor cloud sorting through the key technology of the large number of recent research results, the stability of cathode material from long-term photovoltaic stability, mechanical stability and electrochemical stability of the three directions of analysis, in order to establish a complete set of system evaluation strategy. The evaluation strategy is published on Energy & Environmental Science.          

From the perspective of commercial applications, the need for more targeted research team. This systematic evaluation method is of great importance to the design of high performance cathode catalytic materials and the commercial application of this material in the field of new energy sources. lithium ion batteries becomes more popular into public eye sight, proper regulation is necessary to regulate proper way of market competition, so as to protect the public's safety in all round way. we are making solar batteries under laws and regulations, for example,please take care to use it.
