Tuning the Thermal Conductivity of Silicon Phononic Crystals via Defect Motifs: Implications for Thermoelectric Devices and Photovoltaics

“…Nonetheless, specific applications require materials with low thermal conductivity, such as thermoelectric devices , and photovoltaics. In the former case, it has been shown that it is possible to increase the thermoelectric efficiency of Si-based structures by phonon engineering. , In the latter case, a Si-based layer can be placed between the conductive layers inside the photovoltaic cell, serving both as electrical and heat insulator. − As a heat insulator, it hinders heat flow and prevents overheating and damage to the device. Meanwhile, as an electrical insulator, it prevents the recombination of the electron–hole pair, which is essential for the operation of photovoltaic devices.…”
