Quantifying the performance gain of 100 cm2 bifacial four terminal perovskite-Si tandem modules

open access: yesEPJ Photovoltaics, 2022
Improving the performance of solar modules requires the implementation of both spectral and directional irradiance optimization. The performance of bifacial four-terminal tandem minimodules with a 100 cm2 area is reported, both indoor and outdoor ...

Thermal model in digital twin of vertical PV system helps to explain unexpected yield gains

open access: yesEPJ Photovoltaics, 2023
The business case of novel integrated applications of solar energy is often regarded as a straightforward extrapolation of standard solar parks. But when the design of the solar park is remarkably different from typical solar parks, the operating ...

The Techno-Economic Benefit of Sorption Enhancement: Evaluation of Sorption-Enhanced Dimethyl Ether Synthesis for CO2 Utilization

open access: yesFrontiers in Chemical Engineering, 2020
Dimethyl ether (DME) is an important platform chemical and fuel that can be synthesized from CO2 and H2 directly. In particular, sorption-enhanced DME synthesis (SEDMES) is a novel process that uses the in situ removal of H2O with an adsorbent to ensure ...
