Solar cell fabric is a fabric with embedded photovoltaic cells which generate electricity when exposed to light.
Traditional silicon based solar cells are expensive to manufacture, rigid and fragile. Although less efficient, thin-film cells and organic polymer based cells can be produced quickly and cheaply. They are also flexible and can be stitched onto fabric.
According to an article from New Scientist,[1] researchers have built a photovoltaic cell in the layers around a fiber, creating a tiny cylindrical cell. No longer limited to rooftops and poles, solar collection could work silently and unobtrusively from everyday objects.
Flexible solar cells can be used in humanitarian aid. A makeshift shelter developed by PowerFilm, Inc. called the PowerShade can generate one kilowatt of power. This could help a power emergency equipment at short notice in remote places.
Konarka Technologies produce a thin film polymer-based photovoltaic cell, as a flexible film stitched onto a fabric. The ability to make these cells even smaller is dependent on further research into nanocrystal photovoltaic cells. In theory nanotechnology could provide a way to expand the range of photons a cell could collect, increasing its efficiency while becoming smaller. Konarka, in partner with other institutions, is working on this.
ShadePlex is currently developing a product that integrates thin film photovoltaic modules with architectural fabrics. They will feature a high power output (200 W, 500 W, and 1000 W), and can feed either a battery system or be tied to the grid. Integrating thin film photovoltaics with fabric structures will enable a whole class of buildings to easily integrate renewable energy solutions.
