Hybrid solar cells based on blends of a conjugated polymer, poly-3(hexylthiophene) (P3HT), and silicon nanocrystals (Si NCs) have been developed and characterized. The properties of composite Si NCs/P3HT films which were spun from 1, 2-dichlorobenzene were studied. Under A.M. 1.5 direct illumination conditions (100mW/cm2), devices made with 50wt% 3–5nm Si NCs showed 1.33% power conversion efficiency (PCE) and had a 30% incident-photon-to-current conversion efficiency at 470 nm.

This paper describes the design of a hot gas vane motor. The motor is intended as a portable direct drive actuator powered by a hot gaseous working fluid as an alternative to battery-powered electromagnetic motors. The objective is thus to convert a maximum amount of enthalpy at the inlet into mechanical rotational output energy in a compact and lightweight package. The described motor incorporates a non-circular stator shape and a geometry of injection and exhaust ports to maximize conversion efficiency. An analytical model is developed to describe the torque output and efficiency of the motor. Simulations are performed to provide insight into the motor behavior and characterize the expected motor performance.

Different Levels

With current technology, UV filters are essential to ensure long-term dye-sensitized solar cell (DSC) stability. Blocking photons, however, will have an obvious effect on device performance and upon its incident photon-to-current conversion efficiency (IPCE). Filters have been applied to DSC devices with a range of cut-off wavelengths in order to assess how different levels of filtering affect the performance and IPCE of devices made with three different dyes, namely N719, Z907, and N749. It is shown that dyes that extend their IPCE further into the NIR region suffer lesser relative efficiency losses due to UV filtering than dyes with narrower action spectra. Furthermore, the results are encouraging to those working towards the industrialisation of DSC technology. From the results presented it can be estimated that filtering at a level intended to prevent direct band gap excitation of the TiO2semiconductor should cause a relative drop in cell efficiency of no more than 10% in forward illuminated devices and no more than 2% in reverse illuminated devices.
