Rapid Evaluation System for Photovoltaic Cell and Thermoelectric Generator Hybrid Devices Depending on Temperature via Transparent Heater

In this work, we demonstrate an efficient measurement system suitable for photovoltaic cell and thermoelectric generator (PV-TEG) hybrid devices, which employs a large-area (160 mm × 160 mm) transparent heater (TH). The TH can simultaneously transmit solar radiation and effectively heat the PV-TEG hybrid devices. The resulting TH incorporated measurement system enables the rapid measurement of hybrid devices with a larger range of temperatures. In addition, the measurement system exhibits superior reproducibility with a negligible difference in efficiency (<1%). The method can accelerate the development of PV-TEG hybrid devices with various temperature conditions and without long waiting times.
