Enlitech’s SS-X solar simulator makes the breakthrough possible.
In July 2021, Nature Photonics (Impact factor: 38.77) published a report by Hong Kong Polytechnic University, Wuhan University, and UCLA. An effective method to reduce the photovoltage loss (dimensionally graded perovskite formation; DGPF) by mining interface defects. The halide perovskite solar cells can improve the power conversion efficiency (PCE), and further reduce the bandgap voltage offset (bandgap-voltage offset; WOC) and the non-radiative composite photovoltage loss (ΔVOC, nr). The solar simulator and standard reference solar cell from Enlitech are used to study the effect of DGPF on perovskite solar cells. The authors get over 23% certified PCE.
