Abstract
In a PV module the Jsc is impacted by multiple factors such as geometrical effects, reflection on interfaces and absorption properties of the module components. A major contributer to parasitic absorption are encapsulation materials which are based on different polymers (ethylene-vinyl acetates and polyolefins) with different UV-properties (UV-absorbing and UV-transparent). This raises the question which material to use and how to find the optimal material for a given solar cell. This can be done with simulations of cell-to-module (CTM) losses. However the optical properties of those encapsulating polymers need to be known. In this work multiple encapsulants are characterized in a wavelength range from 300 to 1200 nm to determine their optical constants. Those constants are used for ray-tracing simulations of PERC+ silicon half cell modules with glass or backsheet rear sides to identify losses in Jsc due to absorption in those materials. To gain further information about optical CTM loss mechanisms of these encapsulation materials different rear sides are simulated. As a main conclusion it is shown that encapsulants and rear sides can be optimized independently to maximize the module Jsc. This can reduce the number of required experiments for a number of L encapsulants and M rear sides from L x M to L + M - 1 when optimizing the optical properties of a solar module.
