SEMI PV57 - Test Method For Current-Voltage (I-V) Performance Measurement of Organic Photovoltaic (OPV) and Dye-Sensitized Solar Cell (DSSC) and Perovskite Solar Cell (PSC) -

Abstract

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

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

• The operation principle of OPV/DSSC/PSC 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/PSC has a different spectrum and absorption range with p-n junction than solar cell does.
• OPV/DSSC/PSC needs more photoelectric conversion response time caused by specific material properties.

Therefore, OPV/DSSC/PSC 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/PSC according to its I-V measurement and device qualification. The objective is to focus on OPV/DSSC/PSC I-V performance evaluation either indoors or outdoors, and provide some actions as below.

• Define the specific STC (refer to ¶¶ 5.2.8 and 5.2.9) for OPV/DSSC/PSC when indoors.
• Provide both statistic method (refer to § 8) and testing procedures (refer to § 9) for OPV/DSSC/PSC to reduce measurement errors due to capacitive effect.
• Evaluate the relationship (refer to Figure 4) between short-circuit current (Isc) and spectral correction factor (MMF).
• Approach specific diffuse lighting application when indoors or outdoors.
