Studi Pengaruh Nilai Band Gap pada CsFAPbIxBr3-x Perovskite Terhadap Karakteristik Short Circuit Current Dari Photovoltaics Menggunakan Simulasi MATLAB

Abstract

Solar Power Plant is one alternative to EBT technology, namely Solar Photovoltaics (PV). Thin Film is a new technology from PV. Band Gap which is the minimum energy required for a material to excite electrons from the valence band to the conduction band. The transfer matrix on thin film is used to calculate the optical interference and absorption values in a multilayer array. The transfer matrix method is also a complicated calculation so it needs to be done with a calculation script simulated using Matlab software.The amount of photon energy where if the larger the band gap then the fewer photons have enough energy to produce electron pairs and holes and low energy photons do not have enough energy to lift electrons from the valence band to the conduction band. The optimum thickness in each layer in the 11.62 eV – 1.80 eV Gap Band is lowest ranging from 20 nm and 60 nm and highest ranges from 180 nm and 1000 nm. While the highest Jsc value in the Gap Band is 1.62 eV with a value of 17.29 mA / cm2 and the lowest Jsc value in the Gap Band is 1.80 eV with a value of 12.84 mA / cm2.
