Multi-Channel Solar Cell Evaluation for Long-Term Exposure Testing
The ADCMT SS9610 evaluates photovoltaic conversion efficiency and degradation characteristics over extended periods by automatically measuring and logging the I-V characteristics of multiple solar cells.
The system records key solar cell parameters including short-circuit current, open-circuit voltage, maximum-power current and voltage, fill factor, conversion efficiency, series resistance, and parallel resistance. Environmental measurements such as solar radiation, temperature, humidity, and wind speed can also be incorporated into the evaluation.
Up to 50 Channels
Multi-channel measurement using one scanner with additional scanner cards
Long-Term Evaluation
Tracks conversion efficiency and degradation characteristics over time
Automated I-V Logging
Records Isc, Voc, Ipmax, Vpmax, FF, efficiency, and resistance parameters
Indoor or Outdoor
Supports solar simulators, exposure testing, and environmental measurements
A configurable ADCMT source monitor performs 0 V-crossing I-V sweeps, while the scanner connects multiple cells to the measurement system. The standard configuration supports 10 channels and can be expanded to 50 channels with scanner cards. Systems requiring more than 50 channels can be customized by adding scanners.
Measurement timing, suspended periods, channel-switching intervals, and the number of measurements can be scheduled through the system software. Logged data is automatically stored in daily or monthly CSV files for stable long-duration testing.

Multi-Channel PV Cell Measurement
The standard system supports 10 channels and can be expanded to a maximum of 50 channels using additional scanner cards. Larger customized systems can be configured by adding scanners.
Long-Term Degradation Evaluation
Periodic I-V measurements track photovoltaic conversion efficiency and degradation characteristics during extended indoor or outdoor exposure testing.
Comprehensive Solar Cell Parameters
Logs Voc, Isc, Ipmax, Vpmax, maximum power, fill factor, conversion efficiency, series resistance, parallel resistance, and complete I-V measurement data.
Environmental Data Integration
Supports up to five environmental measurement inputs, including solar radiation, temperature, humidity, wind speed, and panel temperature.
Selectable Source Monitor
The source monitor can be selected according to the required cell voltage and measurement-current ranges, with bipolar output enabling I-V evaluation across 0 V.
Programmable Measurement Scheduling
Configure the measurement start date and time, suspended periods, measurement intervals, channel-switching intervals, and number of measurements.
Load Resistance Connection
Optional actuator-card configurations can connect cells not currently being measured to load resistances, allowing degradation evaluation under conditions closer to actual operation.
Automatic CSV File Creation
Daily or monthly file creation prevents excessive file growth and supports reliable long-term data collection, with configurable file names and storage destinations.
Solar Simulator Control
Digital I/O or contact-signal output can control a solar simulator or other light-source shutter as part of an automated measurement sequence.
