Literature review: current development of perovskite solar cells (3 units)

 

Perovskite solar cells (PSCs) are a rising star on the field of photovoltaics, and recently it has been demonstrated in the lab to achieve high power conversion efficiency (PCE) towards 25%. However, the practical application of PSCs will be severely limited by, e.g., the photovoltaic degradation induced by moisture, light exposure and temperature change.

In this project, you will review literatures to investigate the fabrication of perovskite materials, PSC assembly, strategies to enhance photovoltaic performance and stability, photovoltaic degradation mechanism, and flexible PSCs. It is expected for you to answer the questions how to fabricate a PSC with high PCE, high mechanic stability and affordable cost.



Hand-powered paper centrifuge (3/6 units) - Student id: 17217555

 

In a global-health context, commercial centrifuges are expensive, bulky and electricity-powered, and thus constitute a critical bottleneck in the development of decentralized, battery-free point-of-care diagnostic devices. In this project, you will assemble an ultralow-cost, lightweight, human-powered paper centrifuge to separate some mixture solution samples, for example, pure plasma from whole blood.
