In this study, we provide the reader with an overview of quantum dot application in solar cells to replace dye molecules, where the quantum dots play a key role in photon absorption and excited charge generation in the device. The brief shows the types of quantum dot sensitized solar cells and presents the obtained results of them for each type of cell, and provides the advantages and disadvantages. Lastly, methods are proposed to improve the efficiency performance in the next researching.

Solar energy is an alternative source of energy that can be used to replace fossil fuels. Various types of solar cells have been developed to harvest this seemingly endless supply of energy, leading to the construction of solar cell devices, such as dye-sensitized solar cells. An important factor that affects energy conversion efficiency of dye-sensitized solar cells is the distribution of dye molecules within the porous semiconductor (TiO 2 ). In this paper, we formulate a continuum model for the interaction between the dye molecule Tris(2,2 ′ -bipyridyl)ruthenium(II) (Ru(bpy) 3 2 + ) and titanium dioxide (TiO 2 ) semiconductor. We obtain the equilibrium position at the minimum energy position between the dye molecules and between the dye and TiO 2 nanoporous structure. Our main outcome is an analytical expression for the energy of the two molecules as a function of their sizes. We also show that the interaction energy obtained using the continuum model is in close agreement with molecular dynamics simulations.

In this paper we present fabrication and experimental results to the field of dye-sensitized solar cells, more particularly relates to Syzygium cumini fruit dyes as sensitizers. A dyes molecule from Syzygium cumini fruit adsorbs to each particle of the titanium dioxide. A dyes molecules act as absorbance of the visible light. Simultaneously, titanium dioxide plays a role as griping and absorbs place for natural dye molecules. Thus, an important component for overall performance in term of efficiency for dye-sensitized solar cells is the photogeneration from the absorbed dye in titanium dioxide. The dye-sensitized solar cells fabricated with the extract of Syzygium cumini fruit dye produced fill factor of 0.317 and conversion efficiency of 2.0 %.
