Because of their elasticity， light weight， little cost， and wide-area applications， besides that a notable increase in power conversion efficiency （PCE）， organic solar cells have recently caught the concern of numerous researchers. In the current project， we created a variety of organic small compounds as donor materials by using Gaussian 09. Our design approach entails swapping the core part， which is benzothiadiazole （BT）， based on a derivative of oxadiazole， as the terminals on both sides of the prototype compound （RM） with a variety of fragments to improve the electronic and optic characterization and performance for PCE in organic solar cells. Careful theoretical consideration under density-functional theory DFT and time-dependent density functional theory TD-DET at the B3LYP/6-31G（d，p） basis set was made to find the maximum absorption wavelengthλmax， the efficiency of light harvesting （LHE）， excitation energy (EX)， HOMO and LOMO levels， energy band gap (Eg)， dipole moment （ρ）， the DOS， ionization potential （LP）， electron affinity （EA）， fill factor （EF）， and open circuit voltage (Voc) of molecules RM and TSstudied in a methodical manner. Calculated values revealed that proposed compounds T1-T4 can be encouraging materials for manufacturing organic solar cells as a donor tiny compound with acceptor PC61BM to predict a rise in power conversion efficiency （PCE） owing to their possession of proper values for some optical and electronic features， like the lowest HOMO level， narrower band gaps， and a greater absorption wavelength compared with the reference model RM.

控制理论与应用（英文版） 2013年第1期11卷 103-107页

We consider optimal control of a bilinear parabolic equation. The determination of such control requires to minimize a given energy performance measure. The performance measure of the system is taken as a combination of its modified total energy and the penalty term describing the approach used in the control process. Using an appropriate transformation modal expansion, the optimal control of a distributed parameter system （DPS） is simplified into the optimal control of a bilinear time-varying lumped parameter system （LPS）. A computational efficient formulation to evaluate the optimal trajectory and control of the system is determined. It is based on the parametrization of the state and control variables by using finite wavelets. Numerical examples are provided to demonstrate the applicability and the efficiency of the proposed method and the results are quite satisfactory.

In this paper, we propose an ellipsometer using a phase retarder and rotating polarizer and analyzer at a speed ratio I：N. Different ellipsometric configurations are presented by assuming N = 1, 2, and 3. Moreover, two values of the offset angle of the retarder are considered for each ellipsometric configuration. The Mueller formalism is employed to extract the Stokes parameters, from which the intensity received by the detector is obtained. The optical properties of c-Si are calculated using all configurations. A comparison between different configurations is carried out considering the effect of the noise on the results and the uncertainties in the ellipsometric parameters as functions of the uncertainties of the Fourier coefficients. It is found that the alignment of the phase retarder has a crucial impact on the results and the ellipsometric configuration with speed ratio 1：1 is preferred over the other configurations.

In this paper we propose theoretically a set of ellipsometric configurations using a rotating polarizer, compensator, and analyzer at a speed ratio of N1ω：N2ω：N3ω. Different ellipsometric configurations can be obtained by giving different integral values to N1, N2, and N3. All configurations are applied to bulk c-Si and GaAs to calculate the real and imaginary parts of the refractive index of the samples. The accuracies of all ellipsometric configurations are investigated in the presence of a hypothetical noise and with small misalignments of the optical elements. Moreover, the uncertainties in the ellipsometric parameters as functions of the uncertainties of the Fourier coefficients are studied. The comparison among different configurations reveals that the rotating compensator–analyzer configuration corresponds to the minimum error in the calculated optical parameters.
