The PV module manufacturers have a variety of backsheets. However, choosing the right backsheet for specific PV module design is often very costly, time-consuming and complex. Due to recent upsurge in off-grid solar applications and downward cost pressures, the PV industry has started various R&D initiatives to produce low cost backsheet variants.

The PP backsheet exhibits a significantly higher reflectance over the whole solar wavelength range (hemispheric reflectance of 80.4%) than the PPF backsheet (hemispheric reflectance of 68.6%). The higher reflectance results in an increased back-scattering and back-reflection of the incident light onto the cell, thus increasing the power output ...
