NPL researchers have demonstrated the direct application of the newmethod to the optimisation of organic solar cells. Transparent, flexible and low-cost organic solar cells could offer a solution to large- scale, low-carbon energy generation. However, a lack of analytical techniques that can simultaneously probe device properties at the nanoscale has presented a major obstacle to their optimisation. The new STEOMmethod developed at
NPL addresses this problem, providing simultaneousmeasurements of topography and electrical, chemical and optical properties, while also being non- destructive, causing no damage to the samples beingmeasured. The breakthrough was achieved by combining plasmonic optical signal enhancement with electrical-mode scanning probe microscopy. This allows the relationship between surfacemorphology, chemical composition and current generation in operating organic solar cells to be explored at the nanoscale for the first time. The research was carried out in
collaboration with Imperial College London,Hangzhou Dianzi University (China), the University of Duisburg-Essen (Germany) and King Abdullah University of Science and Technology (Saudi Arabia).

level test, validation and calibration of batterymanagement systems (BMSs). The BCS-LABCAR is a high-precision battery cell simulator that emulates the behaviour of individual battery cells and packs across a range of challenging operating conditions – cell-balancing, over-charging, deep discharging or pulse operation. The systemis highlymodular and thus scalable to emulate battery packs froma single cell all the way up to 200 cells. The systemfurthermore contains a real-time simulation target (ETAS LABCAR-RTPC) which enables the easy integration of third-party batterymodels – such as theMapleSimbatterymodel – and their execution in real-time.
SIGNAL ANALYSER FOR AUTOMOTIVE AND AEROSPACE TESTING
regard to test, validation and calibration. Development cycles are continuously shortened and budgets for real prototypes are limited.High-fidelity batterymodels are computationally intensive and hence hard to run in real-time; the process of parameterisation is time-consuming and typically requires a deep understanding of the battery cells. Besides these challenges, the test systemhardware often does not have the necessary signal accuracy, current range for balancing or cell emulation dynamics to exactly replicate the results fromthe high-fidelity batterymodel. The combination of ETAS hardware and Maplesoft plantmodel addresses these challenges. The ETAS battery cell simulator (BCS-
LABCAR) is a hardware-in-the-loop systemwhich specifically targets the signal-
