In this video the most efficient solar cells tested in the lab are listed in addition to the most efficient panels available in the market.

The list includes all significant PV technologies such as crystalline silicon, organic solar cells, Multi-junction solar cells, Cd Te, Ga As and Pervoskite etc..

It must be noted that NREL (National Renewable Energy Laboratory) upgrades the recognized efficiency chart for PV lab efficiencies every 6 weeks. The values listed here in are referenced in the NREL efficiency graph and from own research. The graph can be retrieved from the following link:

Note that efficiency noted in the lab will always be higher than practical efficiency.
