Development of Flexible Tandem Photovoltaic Devices Based on Stable Lead-Free Perovskites - 2025/2027

This project focuses on the creation of flexible tandem photovoltaic solar cells using lead-free perovskites as the semiconductor material. Perovskites are promising due to their high efficiency and low cost, but many formulations contain lead, which poses environmental risks. By eliminating lead and designing bendable devices, the project aims to develop a safer and more versatile technology.

A key goal is to ensure that these devices can withstand extreme desert conditions—intense sunlight, high temperatures, daily thermal variations, and dust—making them especially suitable for arid regions such as northern Chile, which has significant solar potential.

The project seeks to produce photovoltaic devices that are not only efficient but also durable, cost-effective, environmentally safe, and adapted to demanding environments. This could accelerate solar deployment in remote areas, reduce energy dependence, and contribute to the transition toward clean energy.
