Progress in Photovoltaics: Research and Applications © John Wiley & Sons Ltd Early View (Online Version of Record published before inclusion in an issue) These Early View articles are now available on Wiley Online Library Research Articles From cells to laminate: probing and modeling residual stress evolution in thin silicon photovoltaic modules using synchrotron X-ray micro-diffraction experiments and finite element simulations Sasi Kumar Tippabhotla, Ihor Radchenko, W.J.R. Song, Gregoria Illya, Vincent Handara, Martin Kunz, Nobumichi Tamura, Andrew A.O. Tay and Arief S. Budiman Version of Record online: 12 APR 2017 | DOI: 10.1002/pip.2891 Residual stress in crystalline silicon cells in photovoltaic modules was investigated using Synchrotron X-ray Micro-diffraction before and after encapsulation. The mechanism of residual stress evolution was explained by virtue of 2D and 3D finite element simulations, which are in good agreement with the experimental results. Highly localized bending of the cell near the solder joint after encapsulation was found to be the reason for high stress in the encapsulated cells. Enhancing the power output of PV modules by considering the view factor to sky effect and rearranging the interconnections of solar cells Assaf Peled and Joseph Appelbaum Version of Record online: 10 APR 2017 | DOI: 10.1002/pip.2896 Photovoltaic modules experience current mismatch due to inhomogeneous incident diffuse irradiation which produces variations in the module's view factor to sky. To resolve this, illustrated above are the original all-series topology (A) accompanied by four proposed solar cell configurations (B)–(E), each of which establishes a positive power gain with respect to (A). Conversion from (A) to (B) is shown to create a power gain that may peak 19% at Lindenberg, Germany. The energy supplemented per module annually is equally remarkable. Nanoscale insight into the p-n junction of alkali-incorporated Cu(In,Ga)Se2 solar cells Adam Stokes, Mowafak Al-Jassim, Andrew Norman, David Diercks and Brian Gorman Version of Record online: 5 APR 2017 | DOI: 10.1002/pip.2883 Eight atom probe specimens were presented and gave a never-seen-before statistical representation of the variable chemistries at the p-n junction at small length scales of alkali-incorporated Cu(In,Ga)Se2 solar cells. A model to relate chemistry to band profiles such as the shifts in conduction band minimum, valence band maximum, and bandgap is also presented. To unsubscribe from this alert please click here.
