Cell junctions [1] or junctional complexes, are a class of cellular structures consisting of multiprotein complexes that provide contact or adhesion between neighboring cells or between a cell and the extracellular matrix in animals. [2] They also maintain the paracellular barrier of epithelia and control paracellular transport.
WebIn Concentrating Photovoltaics (CPV), a large area of sunlight is focused onto the solar cell with the help of an optical device. By concentrating sunlight onto a small area, this technology has three competitive advantages: Requires less photovoltaic material to capture the same sunlight as non-concentrating pv.
