穩定無鉛與少鉛多維度鈣鈦礦奈米結構之光電特性與應用

The ways we generate energy have already cause serious climate change and environmental pollution. Solar cells are one of the most important renewable energies. Recently, solar cells based on organic-inorganic halide perovskites have attracted considerable attentions because of their solution processes and low-cost materials. The most surprising thing is that the power conversion efficiency of the perovskite solar cells increased from less than 3% to higher than 20% in less than 5 years. However, the perovskite materials used nowadays show no air and thermal stabilities and hinder their possible commercialization in the future. This project aims at realizing efficient perovskite electronics with air and thermal stabilities in four years. We will synthesize Lead-free or low Lead multidimensional perovskite materials with better air stabilities. We will prepare single crystals, nanowires, polycrystalline films and quantum dots based on these multidimensional perovskite materials. Currently, we have realized many nanoparticles of lead-free perovskite materials. White LEDs were also realized based on these materials.
