We utilize fully covered thin layer of transparent MoO3/Ag/ZnS as the top electrode for Si nanocone/PEDOT:PSS hybrid solar cells. By adjusting the geometrical parameters systematically, the optimized PCE was realized as 5.12%.

The Individual

Hybrid solar cells consist of organic as well as inorganic substances. An organic compound absorbs light and transports holes whereas an inorganic compound is an acceptor and transports electrons. Hybrid solar cells were fabricated on glass slides pre-coated with indium tin oxide (ITO) which itself acts as a cathode. Poly(3,4 ethylenedioxythiophene)polystyrenesulfonate (PEDOT:PSS) was coated in order to avoid a short circuit between the layers and also to smooth the surface of ITO. A photoactive layer which consisted of poly(3-hexathiophene) (P3HT), TiO2 and star dispersant was coated over the PEDOT:PSS layer. Gold/molybdenum was sputtered as an anode material. Star dispersant was added to the active layer in order to improve the performance of the solar cell. Introduction of star dispersant increases the interfacial area and in turn the exciton dissociation. Atomic force microscopy (AFM) was used to measure the thicknesses of the individual layers and also to obtain a topographical view of the cell surface to ensure the uniformity of the deposited layers. Absorption and photoluminescence spectra were measured to characterize the solar cell. Finally, current–voltage characteristics were measured to ensure that the solar cell acts as a diode.

In this paper, we present our work on high-efficiency multi-junction polymer and hybrid solar cells. The transfer matrix method is used for optical modeling of an organic solar cell, which was inspired by the McGehee Group in Stanford University. The software simulation calculates the optimal thicknesses of the active layers to provide the best short circuit current (JSC) value. First, we show three designs of multi-junction polymer solar cells, which can absorb sunlight beyond the 1000 nm wavelengths. Then we present a novel high-efficiency hybrid (organic and inorganic) solar cell, which can absorb the sunlight with a wavelength beyond 2500 nm. Approximately 12% efficiency was obtained for the multi-junction polymer solar cell and 20% efficiency was obtained from every two-, three- and four-junction hybrid solar cell under 1 sun AM1.5 illumination.
