Current Trends in Quantum Dots Solar Cells
Bavani Thirugnanam, Sivakami. A, Madhavan Jagannathan
Quantum dots (QDs) are zero- dimensional semiconductor structure exhibits tremendous applications in transistors, LEDs, photovoltaic cells, DNA imaging and photodetectors. The theoretical efficiency of QDs in photovoltaic cells is 40% but practically is lesser than the dye-sensitized solar cells. There are many recent developments focused on the use of different components like QD sensitizer, counter electrode, photoanode, electrolyte in quantum dot Sensitized Solar Cells (QDSSCs). The various synthesis methods are also contributing to enhance the efficiency of QDSSCs, open-circuit voltage, short-circuit current density and fill factor. The easily tunable band gap of QDSSCs is showing major improvement in the photovoltaic fields. The first practical efficiency of QDSSCs is recorded as 0.12% but now it is improved as 18% and many researchers are analyzing different factors to improve the efficiency of QDSSCs comparable with other solar cells.
