Abstract
We calculated the energy yields of perovskite/CIGS tandems for real world irradiance and temperature variations.
Highlights
The photoconversion efficiencies (PCEs) of polycrystalline, thin- lm photovoltaic (PV) devices based on CdTe, Cuy(In1ÀxGax)Se2 (CIGS), and metal halide perovskite have all exceeded 22% under standard test conditions (AM1.5G irradiance, 25 C).[1]
Our results indicate that the AM1.5 PCE optimization is not as sensitive to the subcell bandgaps when the perovskite layer is relatively thin
To understand why the perovskite/CIGS tandem devices are so forgiving and able to yield very high PCEs in a variety of different con gurations we examined the external quantum efficiencies (EQEs) response in greater detail
Summary
The photoconversion efficiencies (PCEs) of polycrystalline, thin- lm photovoltaic (PV) devices based on CdTe, Cuy(In1ÀxGax)Se2 (CIGS), and metal halide perovskite have all exceeded 22% under standard test conditions (AM1.5G irradiance, 25 C).[1]. AM1.5 PCE We modeled 2T and 4T perovskite/CIGS tandem devices using materials and device structures that have been shown to yield high performance results in experiments[13,16,21,40] (Fig. 1(a) and (b)).
