Optimasi Teoritik Ketebalan Lapisan Aktif Perylene Tetra Carboxylic Dianhidride (PTCDA) pada Sel Surya Organik Untuk Mendapatkan Efisiensi Maksimum

Abstract

A theoretical study was made on thickness optimizing of photoactive layer 3,4,9,10-perylene tetra carboxylic dianhidride (PTCDA) in resulting maximum Incident Photon to Current Efficiency (IPCE) of organic solar cell which is composed of glass/ITO (Indium Tin Oxide )/CuPc ( copper phthalocyanine) /PTCDA (3,4,9,10-perylene tetra carboxylic dianhidride )/Al. The calculation is based on the assumption that photocurrent generation is the result of excitons generation in PTCDA photoactive layer, that diffuse to CuPc/PTCDA interface and finally dissociated to be free charge carrier, electron and hole. The optimum thickness of PTCDA layer that gives maximum IPCE is 34 nm at the wavelength 467 nm. The highest IPCE is 1,106 %.
