[Smec2019] Study of Matter at Extreme Conditions (SMEC-2019) Miami

[Lee, Seung-Hun (sl5eb)]

Dear Profs. Saini and Mizokawa,

Thank you for the kind invitation. I accept.

However, I would like to present a talk on solar cell perovskites in the Symposium session "Intrinsic structure of layered functional materials”.

Below is the abstract that I will submit.

Thank you again and looking forward to meeting you at the meeting.

New Materials for Next Generation Printable Solar Cells

The realization of economical renewable energy technologies is critical for securing long term prosperity of mankind and mitigating the threat of climate change. Power from the Sun is the most abundant source of renewable energy. In just one hour, more solar energy hits the Earth’s surface than humanity uses in an entire year. Therefore, development of solar cells that can produce electrical power at a cheaper rate than fossil fuel based electricity is highly desirable. However, only about 1 percent of the world’s energy production currently comes from solar cells. This is because the conventional technologies, mostly based on silicon solar cells, are too expensive to be competitive with energy generated by burning fossil fuels. What is needed is research on new solar cell materials that can be fabricated into solar cells with high-efficiency and low-cost simultaneously.

Hybrid Organic-Inorganic perovskites (HOIPs) have recently been discovered as one of the most promising next generation solar cell materials. Solar cells based on HOIPs have achieved high efficiency that rivals that of the conventional silicon solar cells. At the same time, HOIPs can be deposited on surfaces from ink solutions which enable low-cost and high-throughput manufacturing of solar cells as if printing out newspapers. In this talk, I will present our recent research that revealed microscopic mechanism of the photovoltaic properties of HOIPs.[1-3]

This decision was driven by economic reasons since the cost to the participants for a similar land-based meeting in the Miami area is estimated to be much higher.
