EPFL2023Electrical Losses Mitigation in Silicon Heterojunction Solar Cells
To overcome the worldwide challenges of climate change, photovoltaics is foreseen to play a significant role in the world electricity production. Nowadays, single junction crystalline silicon (c-Si) based solar cells hold the largest share of the global ph ...
EPFL2021Extraction of p-n junction properties and series resistance in GaAs nanowire-based solar cells using light concentration
Anna Fontcuberta i Morral, Dmitry Mikulik, Pablo Romero Gómez, Ian Nachemson
Series resistance in solar cells limit their maximum conversion efficiency and thus should be minimized. Generally, such losses originate from deficiencies at the contact or absorber level. Quantifying them is the first step for tackling its reduction. In ...
IOP PUBLISHING LTD2019Full-Area Passivating Contacts with High and Low Thermal Budgets: Solutions for High Efficiency c-Si Solar Cells
Today more than 90% of the global PV market is covered by c-Si solar cells which are limited by recombination losses at the metal-semiconductor interface. This recombination path can be avoided by separating the metal from the c-Si wafer by introducing a b ...

Jun Ho Yum, Soo-Jin Moon, Peter Chen, Meng Li
Considering the increasing global demand for energy and the harmful ecological impact of conventional energy sources, it is obvious that development of clean and renewable energy is a necessity. Since the Sun is our only external energy source, harnessing ...
MDPI2016Lithium Fluoride Based Electron Contacts for High Efficiency n-Type Crystalline Silicon Solar Cells
Aïcha Hessler-Wyser, Quentin Thomas Jeangros, Stefaan De Wolf, Mahmut Tosun
Low-resistance contact to lightly doped n-type crystalline silicon (c-Si) has long been recognized as technologically challenging due to the pervasive Fermi-level pinning effect. This has hindered the development of certain devices such as n-type c-Si sola ...
Wiley-VCH Verlag Berlin2016Introducing rigid pi-conjugated peripheral substituents in phthalocyanines for DSSCs
A new carboxy-Zn(II) phthalocyanine bearing rigid 2,6-diarylphenyl peripheral substituents linked to the macrocycle through alkynyl spacers has been prepared by a convergent approach, which implies a triple Sonogashira coupling between the formyltriiodoZnP ...
World Sci Publ Co Inc2016Perovskite-Hematite Tandem Cells for Efficient Overall Solar Driven Water Splitting
Michael Graetzel, Nripan Mathews
Photoelectrochemieal water splitting half reactions on semiconducting photoelectrodes have received much attention but efficient overall water splitting driven by a single photoelectrode has remained elusive due to stringent electronic and thermodynamic pr ...
American Chemical Society2015Computational studies for the characterization and design of dye sensitized solar cells (DSSCs) with improved efficiencies
During millions of years of evolution, all creatures have found their ways of harvesting, storing and utilizing the energy coming from the sun. Plants use photosynthesis to convert carbon dioxide to glucose. With a low efficiency of only 3%, plants still c ...
EPFL2015NIR sensitive organic dyes for tandem solar cells and transparent photodiodes
