A review of toxicity assessment procedures of solar photovoltaic modules

Remanufacturing of perovskite solar cells

“…The definition of ‘homogeneous material’ is “a substance or group of substances that cannot be mechanically separated” which does not clearly state whether the threshold applies to the entire PV module or only to the perovskite absorber layer. 41,42 If the entire device is considered as homogeneous material, devices with glass substrates would likely comply with RoHS limits based on Moody et al 's estimations. However, compliance might be compromised if the standard applies to individual layers within the device.…”
