In 2014, the Singapore government announced plans to increase the adoption of solar power, including by integrating solar PV systems into the urban environment. Careful planning of a neighbourhood at early design stage, which determines the overall urban m ...
Rough terrain in mid- and high latitudes is often covered with highly reflective snow, giving rise to a very complex transfer of incident sunlight. In order to simplify the radiative transfer in weather and climate models, snow is generally treated as an i ...
In a Swiss case study of the ReCO2st research project, hot water optimization demonstrated a high potential for energy savings with low investment costs. The optimization started with the end user to reduce first hot water consumption. Energy-efficient sho ...
Three novel donor-pi-bridge-donor (D-pi-D) hole-transporting materials (HTMs) featuring triazatruxene electron-donating units bridged by different 3,4-ethylenedioxythiophene (EDOT) pi-conjugated linkers have been synthesized, characterized, and implemented ...
The installation of solar panels on building roofs is increasing and considered as a potential solution to decarbonise the current energy system. However, how to make the best use of this energy is yet to be determined. In this project, two already develop ...
A high penetration of intermittent electricity generation from photovoltaic source, could lead to power curtailment, in order to avoid overloads of the transmission lines, thus reducing the efficiency of the grid. This project focuses on a potential way to ...

Because of its high albedo, snow changes the surface energy balance very signiKcantly and this introduces a strong positive feed-back loop with the local climate. In complex, mountainous terrain, the high albedo causes shortwave solar radiation to be reQec ...
y High specific power, high stowed packing efficiency, low processing cost, and high tolerance against environmental threats (high energy and charged particle radiation) make perovskite solar cell (PSC) a promising candidate for power generation in space. ...
