What is PD IEC TR 63228- Measurement protocols for photovoltaic devices about?
PD IEC TR 63228 is an international standard that discusses solar photovoltaic energy systems, and aims to enhance measurement methods for improved performance of PV technologies.
PD IEC TR 63228 specifies present perspectives on the performance evaluation of emerging PV technologies, specifically OPV, DSC, and PSC devices. These devices present some challenges for accurate measurement under the existing IEC 60904 series of standards, which were developed in the context of silicon wafer solar cells.
The primary objective of PD IEC TR 63228 is the measurement of the current-voltage (I-V) relationship under illumination for the purpose of estimating the device output power, or power conversion efficiency. Where necessary, the report makes reference to the IEC 60904 series which describes the standard approach to measuring the performance of all PV devices.

PD IEC TR 63228 on photovoltaic devices is relevant to:
- Manufacturers of PV devices
- Solar power systems manufacturers
- Solar energy engineering
- Photovoltaic cells manufacturers
- Telecommunication repeater stations
- Navigational aids
Why should you use PD IEC TR 63228- Measurement protocols for photovoltaic devices?
For years, considerable research effort worldwide has been invested in the development of new thin-film PV technologies that may offer lower cost production, new applications or both. In particular, organic photovoltaics (OPV), dye-sensitised solar cells (DSC) and perovskite solar cells (PSC) have generated great interest and the market potential of these products is being explored.
In this regard, PD IEC TR 63228 provides an overview of current best practices for measuring the performance of PV devices.
PD IEC TR 63228 helps identify problems like instability in performance over time; unusual spectral responsivity; small device size; difficulty in measuring temperature; a transient response to an external stimulus; optical interference effects; and non-linear current response to irradiance.
PD IEC TR 63228 summarises current best practices for monitoring the performance of PV devices subject to functional problems. It aims to emphasize where existing standards fail to suit the requirements of this technology, to indicate what additional measurements may be required for correct device efficiency assessment, and how these metrics might be standardized in the future. This also aids in product development and R&D initiatives.
