WebHigher energy band gap hamper efficient absorption of the most part of solar radiations (red and infrared region) that is supposed to be the major reason of lower efficiency of P3HT. The maximum flux density of solar spectrum is found around 700 nm, equivalent to 1.7 eV. 7 The lowering of energy band gap of P3HT can improve the absorption ... WebThe optical absorption range of P3HT:PCBM:ZnPc film was expanded in the range of 400–750 nm by the ZnPc addition. The light with a wavelength of 460 nm was used for excitation of the P3HT, and the measurement region of the photoluminescence is in the range of 300–900 nm.
