摘要

The key causes for the increased attention in quantum dots are their low cost, ability to function in dispersed light, ease manufacture, light weight, and flexibility. This review critically analyses developments in Quantum Dot Sensitized Solar cells (QDSSCs) over the past two decades, synthesizing insights from 178 experimental and theoretical studies. It is also indicated that the computational modelling aids QDSSC optimization by enabling virtual analysis of charge transport, recombination, and interface effects. SCAPS-1D is emphasized for its rapid parametric optimization of layer thickness, doping, band alignment, and defect states, offering reliable performance trends. Complementary tools such as wxAMPS, SILVACO ATLAS, COMSOL, and SETFOS provide heterojunction, multidimensional, optical, and multiphysics insights. This review article begins with an outline of the importance of solar energy, its potential and various generations of PV cells. QDSSCs purpose was elaborated, along with numerous production methods such as direct adsorption (DA), layer by layer deposition (LLD), Colloidal method, chemical solution deposition, and Hydrothermal method. Furthermore, the effect of utilizing computational analysis in the efficiency assessment of the QDSSC was discussed. The paper also examined the components of QDSSCs, comprising progresses in quantum dot sensitizer, electrolyte, photoanodes, and counter electrode. This review analysis also analytically assesses the economic viability of QDSSC by scrutinizing material and production cost and techno-economic meters such as cost per watt and projected levelized cost of energy (LCOE), highlighting key cost parameters, stability restrictions, and trails toward commercially viable quantum dot photovoltaic technologies.
