Gravitationally captured Dark Matter in the form of Weakly Interacting Massive Particles(WIMPs) can annihilate into standard-model particles, such as neutrinos. The IceCube neutrinodetector at the South Pole is an excellent instrument to search for such a neutrino signal fromthe Sun. We present an alternative analysis which improves on previous approaches, in particularin background-dominated regions. Newly developed techniques based on hit clustering and hit-based vetos allow a more accurate reconstruction and identification of events in the detector andthereby a stronger rejection of background. These techniques are also applicable to other IceCubeanalyses and event filters. We present results for a solar WIMP search using the first year of datataken with the completed IceCube detector with 86 strings.
