Beyond using a good light source, you need to align the solar cell toward it properly to get optimal power. Think of it as positioning a sail towards the wind. The best way I have found to align a solar cell towards the sun it to mount a small stick perpendicular to the solar cell''s surface then adjust the cell to minimize the stick''s shadow.
Basically, certifications per se do not tell much about the quality of a module. If you buy a solar module with IEC 61215/ 61730/ 61701 etc. certifications, it means that the certification-holding manufacturer managed to produce a few modules of that type that passed a standard''s (e.g. IEC 61215) tests at the time of applying for certification.

Valve Shell Leakage Test is a test that helps identify the presence of water and other fluids in the valve casing. The test is conducted by pressuring the valve for a specified amount of time, usually one minute or more, and looking for leaks. They are performed on valves like a check, stop, and isolation types. The Types of Valve Testing ...
One of the first and most important consistency checks for a traditional PV cells is the comparison of the photocurrent density extracted from J-V and from the integrated EQE. 6 The EQE, therefore, should be reported for all TPVs and solar concentrators. This further eliminates concern over photocurrent overestimation.
