Studying the properties of ternary PEDOT:PSS thin films for solar cell application Available to Purchase

Poly(3-hexylthiophene):phenyl-C61-butyric acid methyl ester–based organic solar cell is used to investigate the effects of treated poly(3,4-ethylenedioxythiophene):poly(styrenesulfonic-acid (PEDOT:PSS) as a hole transport layer. This layer is treated with different alcohol solutions based on the polarity and mixture. The variation in the polarity of alcohol and their effects on the organic solar cell parameters and behavior were studied and evaluated using different techniques such as atomic force microscopy with the aid of using WSxM software involving the application of two-dimensional fast Fourier transforms analysis. Contact angle measurement is also used to measure the hydrophilicity and hydrophobicity of the PEDOT:PSS solution on the top of substrates. An interdigitated electrode is employed to measure the electrical conductivity of the PEDOT:PSS layers; such results are significant in the solar cell application. The latter is characterized using I–V characteristics and IPCE measurement and the results revealed a good enhancement in the solar cell performance with good stability. Inverted structure is also demonstrated, and the results suggest that the treated PEDOT:PSS layer is promising in the field of inverted OSCs.
