The highest solar cell efficiencies today are reached with four-junction devices under
concentrated illumination. The optimal bandgap combination for realistic four-junction cells …

In this worN we report on a procedure to increase the reproducibility of multi-junction solar
cell growth. This is achieved by applying a systematic offset to room-temperature …

Abstract The Hall Van-der-Pauw method is widely used to assess the electrical properties of
GaSb based semiconductor layers. Semi-insulating GaSb substrates are not available, and …

A study on the microstructure of argon-beam activated n-GaSb/n-Ga 0.32 In 0.68 P bond
interfaces is presented, focusing on the behavior of the bond upon thermal annealing and …

III-V based multi-junction solar cells with 4 to 6 junctions reach the highest efficiencies for the
conversion of solar energy today. We present the latest results on the development of a …

The performance of Al0. 3Ga0. 7As/InP/Ge triple-junction solar cells (TJSC) at the
geosynchronous orbit of Venus had been simulated in this paper by assuming that the solar …

The highest solar cell efficiencies today are reached with four-junction devices under
concentrated illumination. One multi-junction cell concept with prospects of reaching highest …

Given the omnipresence and economical availability of silicon semiconductor processes, it
is no surprise that direct detection particle pixel detectors are commonly fabricated using …

We used surface-activated wafer-bonding (SAB) at low temperatures for the fabrication of
advanced four-junction solar cells. The bonded heterojunctions are optimized regarding …
