General description

Tin(IV) 2,3-naphthalocyanine dichloride (SnNcCl2) belongs to the family of metal based phthalocyanines. They are widely used as an electron donor material in organic photovoltaic (OPV) cells. The use of SnNcCl2 in OPVs increases its power conversion efficiencies since it absorbs light in the near infrared and infra-red portions of the electromagnetic spectrum which accounts for 50% of the solar photon flux.[1]

application

Used as an electron donor material in Organic Photovoltaic (OPV) Cells.[1][2]

Features and Benefits

Has a narrow energy gap which helps in optical absorption beyond a wavelength of 1100 nm in the infrared region.[1]

Understanding and Successfully Applying Materials for Dye-Sensitized Solar Cells

While dye sensitization as the basis for color photography has been accepted for a very long time,1 attempts to use this principle for the conversion of solar light to electricity generally had resulted only in very low photocurrents, below 100 nA/cm
