Abstract Tandem solar cells are suited for space applications due to their high performance, but also have to be designed in such a way to minimize influence of degradation by the high energy particle flux in space. The analysis of the subcell perfor

We characterize the radiation-induced damage of InGaP/GaAs/Ge solar cells for various proton irradiation energies and fluences using conventional current-voltage (I-V) measurements, external quantum efficiency, and a noncontact time-resolved photolum

Organic–inorganic hybrid perovskite solar cells are attracting much attention due to their excellent photovoltaic properties. In these multilayered structures, the device performance is determined by complicated carrier dynamics. Here, we studied p

Copper indium sulfide (CuInS2) nanocrystals (NCs) are nontoxic and cost-effective, making them attractive for use in highly efficient solar cells. However, direct observations of the photoinduced carrier dynamics of CuInS2 NCs to examine the relation

We have reported that a novel quantum structure which we term quantum well island (QWI), a few monolayer thick and sub-micron wide structure, is effective in confining the carriers and enhancing multi-exciton interactions. By embedding InAs-based QWI

It would be very useful if a solar cell's power conversion efficiency could be measured without using electrical contacts, but is that really possible? The authors show that it is, by using time-resolved photoluminescence to characterize a working Ga

In-situ characterization is one of the most powerful techniques to improve material quality and device performance. Especially in view of highly efficient tandem solar cells this is an important issue for improving the cost-performance ratio. Optical

More is always better, right? No, not always. The authors show that in intermediate-band solar cells based on quantum dots, infrared photocurrent generation is strongly nonlinear according to dot density, but $o\phantom{\rule{0}{0ex}}p\phantom{\rule{
