A comprehensive understanding of the performance gain offered by a bifacial module remains an elusive goal for PV owners and EPCs due to variations arising from different design, manufacturing and testing methods. Vicente Parra, Ruperto J. Gómez, José C. Vázquez and Francisco Álvarez of Enertis review the main sources of variability and outstanding uncertainties that must be addressed as the industry seeks to define standard rules for reliably selecting, purchasing and deploying bifacial PV modules

PV is increasingly becoming the cheapest energy source and therefore has become the energy source with the highest yearly capacity additions! Even in 2018, after some scepticism right after SNEC 2018, due to the announcement of the Chinese Government to stop supporting PV as intensively as in 2017, more than 100GW (109GW) have been installed worldwide (we actually bet a crate of beer on that!) and 125GW has been forecasted to be installed in 2019.
When we visit conferences and industrial players, we are very often surprised at how many responsible scientists for PERC production have never heard about the severe degradation effects that PERC devices can show – in particular when talking about LeTID (Light and elevated Temperature Induced Degradation) alias Carrier Induced Degradation (CID).
