AbstractTransfer of monocrystalline silicon films to arbitrary foreign substrates is a promising way for the fabrication of high quality silicon films on foreign substrates, demonstrated by solar cell efficiencies on glass as high as 16.6 % in the past. Transfer technologies also enable the use of flexible substrates. This paper investigates the mechanical stability of the separation layer for two different morphologies. First measurements on the minimum bending radius of unsupported silicon films are presented that allow us to estimate minimum curvatures for flexible monocrystalline devices. Finally, we report the first flexible monocrystalline thin film silicon solar cell of 4 cm2 with an independently confirmed efficiency of 14.6 %.

Thermal Annealing Process

This paper reports effect of modification thin film surface morphology using thermal annealing process in order to enhance organic photovoltaic solar cell performance. The organic photovoltaic solar cell (OPV) were fabricated using bulk heterojunction structure, consist of p-type semiconductor of polythiophene (PT) derivative and an n-type of fullerene, C-61 derivative. The devices structure can be named as Al/LiF/polymer composite film/PEDOT-PSS/ITO. For comparison, the devices were varies; as cast and annealed at 125°C for half an hour to modify the thin film surface structure. The performances of the devices were studied by observing the current-voltage characteristics of the device in dark at ambient temperature and under standard A.M 1.5 illumination. The light conversion efficiency of the resulting photovoltaic devices increases from 0.04% (as cast) to 2.3% after thermal annealing process. As a result, the annealed organic photovoltaic devices, show enhanced efficiencies compared with as cast device due to the enhancement in transport properties of polymer base photovoltaic device.

AbstractThin films of CuIn1-xAlxSe2 have been produced by the selenisation of magnetron sputtered Cu/In/Al precursor layers using elemental selenium and the chemical and physical properties of the layers have been determined for different conditions of synthesis. For optimum conditions of synthesis it was found possible to produce single phase films with the chalcopyrite structure. These films were pinhole free, had good adhesion and were conformal to the substrate. The films had uniform depth profiles as determined using the MiniSIMS. The layers were highly photoactive, indicating that they have the potential to be used to fabricate thin film photovoltaic solar cell devices.
