Climate specific artificial ageing test procedures are developed to allow for an efficient and fast product development of new PV modules/materials optimized for the use in specific climatic regions. Nondestructive characterization of the ageing‐induced changes in the electrical performance is related to material degradation effects. Direct evidence...

We used a validated distributed numerical model to study the performance of six‐segment GaAs monolithically interconnected laser power converter. By studying each electrical loss mechanism separately, we show that perimeter recombinations at low irradiances and Joule losses in lateral conduction layer at high irradiances govern high performance. By...

Compound semiconductor nanowires (III‐V) are promising for development of high‐efficiency, low‐cost, flexible solar cells. Different axial p‐n junction nanowire array solar cell structures are designed and investigated by nanoscale material/device characterization and simulation techniques. It is demonstrated that by varying the junction design of the...

This paper focuses on designing a hybrid triple junction solar cell consisting of a‐Si:H/nc‐Si:H/c‐Si for solar water splitting, as a promising way to store energy in the long term. The triple junction cell achieved an efficiency of 10.57%, open‐circuit voltage (V oc ) of 2.03 V, short‐circuit current density (J sc ) of 8.65 mA/cm2 and...
