The procedures for the measurement of the current-voltage (I-V) characteristics and bifaciality parameters of bifacial photovoltaic devices are analytically described in the IEC 60904-1-2 document [1]. A short summary of these procedures and a bifacial parameter calculation example are provided. . Drawing on in-house modelling and simulation software developed at TÜV Rheinland, this paper explores the power rating issue for bifacial devices, examining the definitions of rear irradiance, measurement test method, power stabilization and verification for type approval. They utilize bifacial solar cells, with the back typically encapsulated in transparent materials (such as glass or transparent back sheets). This article will help you get to know bifacial panels inside out. The Technology Collaboration Programme (TCP) was created with a belief that the future of energy security and sustainability starts. .
