摘要: Abstract In this paper, CdTe quantum dots (QDs) with emission bands at 762 nm and 812 nm were investigated for their use in luminescent down shifting (LDS) layers. Spectral location of yield luminescence the QDs solution proposed that they suitable nanoparticles inclusion LDS dispersed poly (methylmethacrylate) (PMMA) polymer matrix thin films fabricated approximately 70 microns. Significant solar cell efficiency enhancements (approximately 5%–10%) under normal (AM1.5, 25 °C) condition observed after doped PMMA coatings. The experimental results showed increments Voc from 478 to 541 mV, Isc 35 42 mA, Jsc 8.96 10.51 mA/sm2, FF 69.1 77.3% 13.12 19.48%. film was spin-coated on front surface Si enhancing via photoluminescence (PL) conversion antireflection effects.
