Abstract
PSS-doped polyaniline (PANI), which is inexpensive, less acidic, and stable in water, is used as a hole transport material (HTM) of an organic photovoltaic (OPV) cell for efficiently collecting energy from indoor lighting. Therefore, the organic photovoltaic cell exhibits a transmittance of 90% or more. Also, a solar cell according to the present invention has improved environmental stability.
Claims3
An indoor organic photovoltaic (OPV) cell for generating an electromotive force from indoor lighting, comprising:
- a transparent electrode formed on a transparent substrate;
- a hole transport layer formed on the transparent electrode;
- an active layer formed on a upper surface of the hole transport layer and made of a P3HT:ICBA material;
- and
- an upper electrode formed on the upper side of the active layer,
- wherein the hole transport layer is made of a PSS-doped polyaniline (PANI:PSS) material.
A method of synthesizing PSS-doped polyaniline used as a hole transport material in an indoor organic photovoltaic (OPV) cell, comprising:
- purifying aniline (AN) by vacuum distillation;
- dissolving the purified aniline in ultrapure deionized water (DI);
- adding PSS to the solution, followed by stirring;
- mixing an ammonium peroxodisulfate (APS) solution with the AN-PSS solution,
- followed by stirring;
- and
- centrifuging the resulting PSS-doped PANI.
