ABSTRACTIn this work, we report on investigation of p-type semiconducting polymer, {poly(3,4 polyethylenedioxythiophene)-poly(styrenesulfonate)} (PEDOT:PSS) as the p-layer in NIP and PIN hydrogenated amorphous silicon (a-Si:H) solar cells. The rectification ratio of solution-casted diode is ∼ 10, it increases to 3×104 when PEDOT:PSS is deposited by Spin Coating technique. We observed additional photovoltaic effect when light is illuminated through polymer side. So far, best solar cells characteristics observed for PEDOT:PSS/a-Si:H hybrid solar cells are Voc ≈ 720 mV and Jsc ≈ 1 - 2 mA/cm2.

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.

AbstractWe present a study on the performance and analysis of hybrid solar cells comprising a planar heterojunction between between a conjugated donor polymer, P3HT or PCPDTBT, and hydrogenated amorphous silicon (a-Si:H). A comparison of the modeled absorption spectra of the layer stack with the measured external quantum efficiency is used to investigate the contribution of the inorganic and organic material to the photocurrent generation in the device. Although both materials contribute to the photocurrent, the devices exhibit poor quantum efficiencies and low short circuit currents. Bandstructure simulations of the hybrid layer structure reveal that an unfavorable electric field distribution within the planar multilayer structure limits the performance. Using electroabsorption measurements we can show that the electric field is extremelyweak in the amorphous silicon but strong in the organic material. The situation changes drasticallywhen the conjugated polymer is p-doped. Doping not only increases the conductivity of the organic material, but also restores the electric field in the amorphous silicon layer. Optimized hybrid solar cells comprising thin doped P3HT layers exhibit energy conversion efficiencies (ECE) up to 2.8 %.

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.
