A New Development - Synthesizing Nanocrystals for Harvesting Solar Energy

The light absorbing materials available today are not durable and this is one the major factor, why solar energy was not widely accepted in the global market. These light absorbing solar materials used to harvest solar energy have a disadvantage of degrading or overheating over time. Their characteristics of degradation and overheating are the main disadvantages that set them apart from the other energy sources such as hydroelectric generators or wind generators.


A new video protocol has come with a solution by finding a synthesis of two inorganic nanocrystals, which has more durability than the earlier used light absorbing solar materials. According to the article published in Journal of Visualized Experiments (JoVE), the new discovery is focused on liquid stage amalgamation of two nanocrystals. These two nanocrystals produce an electric charge or hydrogen gas on exposure to light.


Dr. Mikhail Zamkov, who is from Bowling Green State University says that these two nanocrystals allow direct and inorganic coupling of the two variants, i.e., catalyst and light absorber. The uniqueness of these two nanocrystals lies in their characteristics of separating charge in different ways and they are inorganic and durable as well.


Between the two nanocrystals, first is rod-shaped whereas the second is composed of stacked layers. The first one allows the charge separation and the second produces electricity. These nanocrystals are easy to recharge and are less sensitive to heat. They can even resist higher amount of heat which is contradictory to the traditional voltaic cells. This discovery will add an important chapter in development of renewable energy and will be highly beneficial for the mankind in the present and the future as well.
