Abstract
A High efficiency Solar Cell is reported using Quasi-mono-crystalline silicon (QMS) with nanovoids. It is used as the Semiconductor material. QMS of suitable dimension shows significant enhancement of optical absorptance which in turn provides higher efficiency of the solar cell. Properties of the QMS have been studied and compared with crystalline silicon. The absorptance of QMS at different wavelength shows higher than that of crystalline silicon. Variation of carrier density with void radius within the material is shown at different acceptor concentration. The absorption co-efficient of material at different wavelength are represented graphically for both QMS and simple silicon. It is observed that absorption co-efficient/cm of QMS is higher than that of silicon and hence solar cell using QMS provides higher efficiency than that of silicon. The reflection loss is simulated considering film stack of porous silicon antireflection coating.
