11 October 2016 Current Affairs: For the first time, Indian researcher has successfully produced a stable, high-efficiency, all-inorganic perovskite nanocrystal solar cells.
It was produced by Abhishek Swarnkar, a research scholar from the Department of Chemistry at Pune’s Indian Institute of Science Education and Research (IISER).
The new inorganic perovskite nanocrystal material has 10.77% efficiency to convert sunlight to electricity. It used cesium to produce the material of cesium lead iodide.
The nanocrystals of cesium lead iodide were reduced to nanometre range. It allowed the material to absorb visible sunlight till 700 nm at ambient temperature.
These nanocrystals were found to be stable from —196 degree C to about +200 degree C. It also converted sunlight to electricity by producing a high voltage of 1.23 volts. These nanocrystals were assembled as a thin film. The thin film was used for making both solar cells and red LEDs.
This research on inorganic perovskite nanocrystal moves away from traditional research based around a hybrid organic-inorganic halide perovskite material.
Though, this traditional hybrid material has high efficiency of over 22% but organic component in it volatile. This material becomes completely unstable under ambient conditions within a short span of time which renders it unsuitable for commercial photovoltaic applications.
