摘要： History of commercial production of solar cells made from polysilicon material (Eff =15 -17%) and from amorphous silicon (Eff = 9 - 12%) has accumulated understanding of deficiencies and limitations of these solar cells. The present design combines following technical requirements: a) ability to harvest energy from widest part of sun spectrum; b) offer highest values of absorption coefficient for photons of the selected part of sun spectrum; c) ensure highest efficiency of conversion of incident photons into electron-hole pairs or photocarriers while ensuring lowest recombination rate; d) The simplicity of fabrication and low cost of mass production.
