      The paper describes the reuse of GaAs wafers after epitaxial lift-off of a thin-film III-V solar cell. Two method for cleaning the wafers have been investigated. It is shown that multiple wafer reuse is possible without degradation in performance of the thin-film cells.

    2. Optimal design of periodic surface texture for thin-film a-Si:H solar cells (pages 160–167)

      Andrej Čampa, Olindo Isabella, Rob van Erven, Patrick Peeters, Herman Borg, Janez Krč, Marko Topič and Miro Zeman

      Article first published online: 11 MAR 2010 | DOI: 10.1002/pip.940

      Optical effects of the rectangular-like periodic textures introduced at the interfaces of a-Si:H solar cells on the short circuit current and external quantum efficiency were studied by 2-D simulations. Three main interdependent effects that occur due to the periodic-texture were analysed in the paper. These three effects are the antireflective effect, improved light scattering and the optical losses in back metal layer and they strongly influence the overall performance of the cell.

    3. Durability of Pb-free solder between copper interconnect and silicon in photovoltaic cells (pages 168–182)

      The superior thermal cycling fatigue durability of Pb-free cells was also confirmed with physics of failure (PoF) analysis, consisting of nonlinear finite element (FE) stress analysis and an energy-partitioning (E-P) solder fatigue model. FE models predict that even the most voided Pb-free cells modeled are twice as durable as void-free Pb-based cells, under the accelerated temperature cycle used in the test. The acceleration factor (AF) predicted by the PoF analysis for a typical service environment is three times higher for Pb-free cells than that for Pb-based cells.

    4. Analysis of one-axis tracking strategies for PV systems in Europe (pages 183–194)

      Thomas Huld, Tomáš Cebecauer, Marcel Šúri and Ewan D. Dunlop

      Article first published online: 11 MAR 2010 | DOI: 10.1002/pip.948

      One-axis tracking PV systems can increase the energy output relative to fixed systems by about 30% in Southern Europe, and by up to 50% in Northern Scandinavia. These systems perform almost as well as true sun-tracking (two-axis) systems, with overall performance typically 1–4% lower, but with significant simplifications in design.

    5. Optimization of moth-eye antireflection schemes for silicon solar cells (pages 195–203)

      Stuart A. Boden and Darren M. Bagnall

      Article first published online: 11 MAR 2010 | DOI: 10.1002/pip.951

      Nanostructured moth-eye antireflection schemes for silicon solar cells are simulated using rigorous coupled wave analysis and compared to traditional thin film coatings. The optimized moth-eye designs are predicted to outperform an optimized double layer thin film coating by approximately 2% for a laboratory cell and approximately 3% for an encapsulated cell. The predicted performance of the silicon moth-eye under encapsulation is particularly remarkable as it exhibits losses of only 0.6% compared to an ideal AR surface.

      Determination of the bulk lifetime of bare multicrystalline silicon wafers (pages 204–208)

      K. Bothe, R. Krain, R. Falster and R. Sinton

      Article first published online: 11 MAR 2010 | DOI: 10.1002/pip.975

      A detailed experimental study demonstrates the relationship between the effective carrier lifetime of unpassivated wafers and their bulk carrier lifetime. Numerical modelling is used to describe this relationship for different surface conditions taking into account the impact of a saw damage layers with poor electronic quality. A prediction of the bulk lifetime from measurements on bare wafers is possible. A simple procedure to implement the analysis for in-line inspection is presented.

      ZnO nanorod arrays as an antireflective coating for Cu(In,Ga)Se2 thin film solar cells (pages 209–213)

      L. Aé, D. Kieven, J. Chen, R. Klenk, Th. Rissom, Y. Tang and M. Ch. Lux-Steiner

      Article first published online: 11 MAR 2010 | DOI: 10.1002/pip.946

      We report the successful application of ZnO nanorod arrays as an efficient antireflective coating for solar cells, in our case Cu(In,Ga)Se2 thin film solar cells. We show a simple electrochemical approach for preparing ZnO nanorods on solar cells and give a detailed analysis of the solar cells' optical and electrical properties before and after the ZnO nanorods deposition as well as a brief comparison between the ZnO nanorod antireflective coating and a conventional single layer MgF2 coating. This novel approach is a solar cells substrate independent process.

      RIE-induced carrier lifetime degradation (pages 214–220)

      Ngwe Soe Zin, Andrew Blakers and Klaus Weber

      Article first published online: 11 MAR 2010 | DOI: 10.1002/pip.935

      Lifetime degradation for samples where RIE etches into silicon is found to be permanent, while for samples where RIE etches only into dielectric layers of SiO2grown on the wafer, the lifetime degradation is found to be reversible. The reversible degradation in RIE-proc essed samples is associated with radiation damage. By reducing the proportion of a wafer exposed to RIE, the degradation of the effective lifetime of RIE-etched silicon samples can be minimised.

      Wire bonding as a cell interconnection technique for polycrystalline silicon thin-film solar cells on glass (pages 221–228)

      Peter J. Gress, Per I. Widenborg, Sergey Varlamov and Armin G. Aberle

      Article first published online: 11 MAR 2010 | DOI: 10.1002/pip.947

      The use of wire bonding as an interconnection and cell tabbing technique for poly-silicon thin-film solar cells on glass is explored. A tabbed and series-interconnected mini-module with an efficiency of 8.3% has been fabricated, which represents a relative increase of 6.6% over the average efficiency of 7.75% for the individual cells prior to interconnection and tabbing. A 9.3% efficient single cell and an interconnected 4-cell mini-module with an efficiency of 5.6% are also reported.
