报告题目：Interface Engineering of Nanostructured Organic-inorganic (Si) for Efficient Hybrid Solar Cells
Abstract: The fast-booming nanotechnology allows people to explore high performance and low cost photovoltaic (PV) devices. Organic-inorganic hybrid solar cells based on nanostructured semiconductor have built up in few years ago, which can benefit the advantages of both organic and inorganic composites. However, the device performances are relatively lower than its pristine all-inorganic PV devices, resulting from the numerous surface defect and improper organic-inorganic phase segregation. In our group, we have developed various nanostructured semiconductors by surface/interface engineering for high-performance solar cell. We have investigated organic-inorganic hybrid solar cells based on nanostructured semiconductor which act as light harvest layer as well as electron transporting layer. Here, we demonstrate that hybrid PVs based on organic conjugated molecular and silicon nanowire (SiNWs) arrays can achieve a high PCE (~13%) by controlling the phase separation as well as surface passivation.
