Solar cells with higher efficiency and lower environmental impact

Environmental impact of solar cells depends on material usage, but also the efficiency of solar energy conversion.

Today´s solar cell market is highly dominated by crystalline silicon solar cells, where the production costs are strongly suppressed, and where the experimental efficiencies are approaching the theoretical limits.

One way of progress towards lower cost and sustainability is to use the solar light more efficiently by fabricating tandem solar cells.

This project aims to develop a technology that fits well to combine with conventional silicon solar cells to a tandem solar cell module.

The technology in the project is based on (Ag,Cu)(In,Ga)Se2 and the research at Uppsala University, where several breakthroughs have enabled high efficiency for solar cells suitable for this application.

In the project, a solar cell module deposited on the front lamination glass will be developed, which will lead to lower kWh costs and a lower carbon foot print.
