Resumen:

In this work, we present the optoelectronic properties in polymorphpus silicon thin films grown by plasma Enhanced Chemical Vapor Deposition (PECVD), starting from diclosorsilane and hydrogen as precursor gases. Variation in the band gap from 1.66 to 2.0 eV as a function of different deposition conditions were obtained. Raman spectrocopy was used to determine the crystalline fraction in the polymorphous silicon thin films. On the other hand the relation of photosensitivity with the RF power and the behavior of diffusion length were studied. A model of a new type of HIT solar cells with band gap and doping gradient is proposed. © 2017 IEEE.
