Abstract
Solar cells (SCs) using ordered silicon nanowires (SiNWs) were fabricated, and their efficiency was analyzed using photocurrent spectroscopy. The use of ordered SiNWs led to an SC efficiency of up to 16%, compared to that of a thin-layer silicon SC. The impacts of wire gauge and arrangement on the efficiency of SCs were analyzed, revealing that a sequential arrangement of ordered SiNWs can increase the external quantum efficiency (EQE) by up to 80%. A comprehensive mechanical analysis of the ordered SiNWs of SC showed that using ordered SiNWs improves carrier transport and reduces the loss of voltage and current generated at high temperatures. Photocurrent spectroscopy was used to measure the optical efficiency produced by SCs with ordered SiNWs, and the results showed that an SC made from ordered SiNWs achieved significantly higher efficiency compared to a traditional silicon SC. The study demonstrates the potential of ordered SiNWs as an effective material to enhance SC performance. This study provides insight of these nanowires (NWs) for achieving maximum efficiency.
