Graphene is used in solar panels:

Transparent electrodes: Graphene is a transparent, flexible material that can be used as an electrode in solar cells. Graphene-based electrodes are a cheaper alternative to the brittle, expensive electrodes typically used in transparent solar cells.

Interfacial buffer layer: Graphene can be used as an interfacial buffer layer in solar cells.
Hole/electron transport material: Graphene can be used as a hole/electron transport material in solar cells.

Photoactive layers: Graphene can be used in photoactive layers of solar cells.
Environmental stability: Graphene's 2D network structure protects solar cells from environmental degradation.

Efficiency: Graphene can be stacked to increase the efficiency of solar cells. Graphene-based perovskite solar cells can have a power conversion efficiency of over 20.3%.
