Abstract

This Standard proposes a performance test method for organic photovoltaic (OPV)/dye sensitized solar cell (DSSC) according to its current-voltage (I-V) measurement and device qualification.

 

The major difference between OPV/DSSC and p-n junction solar cells is photoelectric conversion mechanism, such as:

-        The operation principle of OPV/DSSC uses layers of organic molecules subject to lighting after excitation electronic, then passes to the inorganic/organic layer of the wide energy gap nano-layer and voltage.

-        OPV/DSSC has a different spectrum and absorption range with p-n junction than solar cell does.

-        OPV/DSSC needs more photoelectric conversion response time caused by specific material properties.

 

Therefore, OPV/DSSC shall need specific basis of reference to differ with standard test condition (STC) [AM 1.5G, 25°C, 1000 W.m–2] used by p-n junction solar cell, and also make corrections for spectral issue and reserves extra time for I-V test due to capacitance effect.


This Standard shall develop a performance test method for OPV/DSSC according to its I-V measurement and device qualification. The objective is to focus on OPV/DSSC I-V performance evaluation either indoors or outdoors, and provide some actions as below.

-        Define the specific STC for OPV/DSSC when indoors.

-        Provide both statistic method and testing procedures for OPV/DSSC to reduce measurement errors due to capacitive effect.

-        Evaluate the relationship between short-circuit current (Isc) and spectral correction factor (MMF).

-        Approach specific diffuse lighting application when indoors or outdoors.
