The ocular aberrations (wavefront) can be used to describe the vision defects, and wavefront sensing devices (aberrometers) are used to measure the ocular aberrations (OAs). The Zernike polynomials (ZPs) are currently used ...

Among thin film solar cell materials, cadmium sulphide (CdS) has to been found to be the most suited window material as a heterojunction partner in cadmium telluride (CdTe) based solar cells. By introducing a buffer layer ...
