The cost of producing solar power has dropped dramatically over the past decades, making it competitive – and sometimes even beaten – with fossil fuel energy.

This trend is expected to accelerate as efficiency improvements and new technologies come to market. Thanks to printed solar cells produced at low cost, 1.3 billion people without electricity could today access them.

Paper-thin solar cells they only require an industrial printer to be made and are also cheap to produce. Unlike traditional solar panels, printed solar cells are flexible, making it easy to carry them anywhere.

Printed solar cells have grown rapidly from 3% to 20% efficiency in just a few years. Its success is due to its profitability-simplicity.

However, mass production and its subsequent distribution is not without obstacles. An industrial printer requires an initial capital investment to start production. Printed solar panels can be sensitive to moisture and can lead to lead contamination if broken.

Solar cells printed on paper

Companies like Kyung-In are testing new coatings for these cells to address these issues.

Despite the challenges, printed solar cells can be a powerful tool in the fight against poverty and represent an important step towards saving 100% renewable energy, especially for the poorest communities on the planet.
