Mixing two Organic Dyes to Improvement Solar Cell Efficiency

Abstract

The solar cell efficiency has been improved by using concentrators having mixing two organic dyes; Pyranine and Triglyceride for Oleic acid. The efficiency of the silicon solar cell was measured before and after mixing. A Big improvement was noticed in the solar cell efficiency from (21.57) to (34.16). Also, the (fluorescence & absorption), stokes shift (Δη), radiated lifetime (τ fm ), fluorescence lifetime (τ f ) and quantum efficiency (Q fm ) was calculated.
