12. Quantum Dot Sensitized Solar Cells (QDSSCs)

Quantum Dot Sensitized Solar Cells (QDSSCs) are currently a field of intense research across the globe as they provide a promising cost-effective alternative for efficient energy conversion. The wide acceptance of QDs is due to their exceptional optical properties, size-tunable electro- and photoluminescence, multiple exciton generation (MEG), and broad absorption spectra. However, the progress of QDSSCs is confronted with many challenges. The basic strategies of enhanced photovoltaic characteristics depend on factors like—suppressed charge carrier recombination at the interfaces, improved photon absorption, and construction of tandem structures. Exploiting further nanoscience and nanotechnology will be essential in overcoming these hurdles for achieving better functional quantum dot sensitized solar cells. The current research work focuses on how the prevalent challenges are being overcome in order to develop efficient functioning QDSSC.
