There has been an increasing interest towards organic solar cells after the discovery of conjugated polymer and bulk-heterojunction concept. Eventhough organic solar cells are less expensive than inorganic solar cells but the power conversion energy is still considered low. The main objective of this research is to investigate the effect of the P3HT’s thickness and concentration towards the efficiency of the P3HT:Graphene solar cells. A simulation software that is specialize for photovoltaic called SCAPS is used in this research to simulate the effect on the solar cells. The solar cell’s structure will be drawn inside the simulation and the parameters for each layers is inserted. The result such as the open circuit voltage (Voc), short circuit current density (Jsc), fill factor (FF), efficiency (η), capacitance-voltage (C-V) and capacitance-frequency (C-f) characteristic will be calculated by the software and all the results will be put into one graph.

A Value

By using spin-coating technique, a low bandgap conjugated polymer, poly[2,6-(4,4-bis-(2-ethylhexyl)-4H-cyclopen-ta[2,1-b;3,4-b′]dithiophene)-alt-4,7-(2,1,3-benzothiadiazole)] (PCPDTBT)  and its composite thin films have been prepared. The optical absorption and photoconductive properties with over a wide spectral range, from 350 to 950  nm, were characterized. The obtained results showed that PCPDTBT:10 wt% CdSe  composite is the most suitable for efficient light-harvesting in polymer-based photovoltaic cells. The photoelectrical conversion efficiency (PCE) of the device with  a multilayer structure of ITO/PEDOT/ PCPDTBT:CdSe /LiF/Al  reached a value as large as 1.34% with an open-circuit voltage (Voc) = 0.57 V, a short-circuit current density (Jsc) = 4.29 mA/cm2, and a fill factor (FF) = 0.27. This suggests a useful application in further fabrication of quantum dots/polymers based solar cells.

Betavoltaic Cell

A betavoltaic cell in 4H SiC is demonstrated. An abrupt p-n diode structure was used to collect the charge from a 1mCi Ni-63 source. An open circuit voltage of 0.95V and a short circuit current density of 8.8 nA/cm2 were measured in a single p-n junction. An efficiency of 3.7% was obtained. A simple photovoltaic type model was used to explain the results. Good correspondence with the model was obtained. Fill factor and backscattering effects were included. Efficiency was limited by edge recombination and poor fill factor.

Good light harvesting properties and matched energy levels as well as enhanced Jsc value and high Voc value in solar cells were achieved simultaneously by construction of the D–A–π–A type regular terpolymers of PIDT-DTQ-TT, finally leading to the maximum PCE value of 6.63% in PSCs.

ABSTRACTWe have deposited and analyzed solar cells from mixed SiCI2H2/SiH4 plasmas. Intrinsic and doped films were also grown to explain the cell results. The SiCI2H2 cells have lower fill factor and short circuit current density than the SiH4 cells due to the higher defect densities and lower photoconductivities of SiCI2H2/SiH4 material. Cell results showed low VQC if the n-layer was in contact with an i-layer deposited from SiCI2H2/SiH4. A pure silane buffer layer between the i- and n-layers was needed to attain the standard open circuit voltage. The reduced Voc results from a reduced conductivity of phosphorus-doped SiCI2H2/SiH4 material. However, comparison of doped films showed higher conductivities for boron-doped material grown from the SiCI2H2/SiH4 mixture than from pure silane.
