Abstract
Official abstract text for this publication.
Disinfecting a sample of water includes generating a current using an array of photovoltaic cells, using the current to power an array of light emitting diodes, wherein the array of light emitting diodes emits a germicidal wavelength of radiation, and exposing the sample of water to the radiation. Another method for disinfecting a sample of water includes placing the sample of water within a container, wherein the container includes an array of photovoltaic cells encircling an exterior wall of the container and an array of light emitting diodes encircling an interior wall of the container, placing the container in a location exposed to solar radiation, converting the solar radiation to a current using the array of photovoltaic cells, and powering the array of light emitting diodes using the current, wherein the array of light emitting diodes emits a germicidal wavelength of radiation sufficient to disinfect the sample of water.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for disinfecting a sample of water, the method comprising: generating a current using an array of photovoltaic cells, wherein the array of photovoltaic cells encircles an exterior wall of a container holding the sample, wherein the array of photovoltaic cells comprises a plurality of micro photovoltaic cells, wherein the plurality of micro photovoltaic cells includes flexible thin-film photovoltaic cells; powering an array of flexible light emitti…
