2nd International Online Workshop on Lead-Free Perovskite Solar Cells

Towards eco-friendly perovskite technology

The 2nd International Workshop on Lead-Free Perovskite Solar Cells will be held online from 22 to 23 October 2024. It will be hosted by Helmholtz Centre Berlin for Energy and Materials (HZB).

Through the last decade, perovskite solar cells have achieved remarkable efficiency, with state-of-the-art performance exceeding 26%. Perovskite technology has matured to the point where it stands on the threshold of commercialization. However, the highest-performing perovskite devices are based on lead, which poses environmental risks that might hinder or delay the market reach of this technology. Environmentally friendly alternatives to lead are limited, with tin being the most promising candidate due to its competitive optoelectronic properties. However, the efficiency of tin perovskite solar cells lags far behind their lead counterparts due to significant fundamental challenges such as tin oxidation and energy band mismatch.

To unlock the potential of tin perovskites, we need to consolidate the efforts of the tin perovskite community and pool our resources. We must also increase research into tin perovskites and other possible lead-free technologies to find new solutions and achieve breakthroughs. In this context, the international workshop on lead-free perovskite solar cells stands out as an annual gathering for lead-free perovskite research groups to exchange ideas, foster collaborations, and showcase recent achievements.

The workshop is designed for professors and senior researchers to present their recent achievements and discuss potential future trends. It also aims to provide a platform for junior researchers and students to present their recent lab findings, network, and explore potential career pathways. Making the workshop online and free of charge would encourage participation from group leaders in remote locations and motivate students with limited research budgets to join.
