ABOUT THE CONFERENCE
Transitioning a society towards better sustainability in resource use than now requires much more use of sustainable energy, an enormous challenge for the coming decades.
Solar energy, in the broadest sense, is the only of two resources that can meet our needs. Here amazing developments occurred, especially in photovoltaics, PV, viz. the advent of hal-ide-perovskite (HaP)-based PV, which thoroughly debunked the idea that improving PV is mainly a development issue!
A proven way to higher photon to electrical energy conversion efficiency is stacking a cell with wide-bandgap absorber on a narrow bandgap one, making a tandem cell. In this way high enough voltages can be photo-generated to drive electrolysis for solar fuels without loss of current.
For the first time ever HaP cells make low-cost, effcient tandem concepts feasible.
Not only may HaPs be our ticket to higher photon to electrical energy conversion efficiency / area / $, they challenge our understanding of electronic materials. This basic science issue is what drives the interest of most WIS research and focuses on the questions:
- Why are photovoltages so high; why is the photogenerated carrier recombination so low?
- Why are defect densities so low; can they self-heal (and if so, how)?
This one-day workshop builds on the participation of WIS scientists in a Solar ERAnet project and in a StableNextSol initiative, as well as in national projects, and the close ties with the Helmholtz Centre Berlin, to bring together Israeli researchers with those from several European countries.
Also, while HaPS are made of earth-abundant, readily available elements, they contain (spar-ingly) soluble lead. Novel compositions to replace, or intelligent ways to insolubilize lead are needed, the topic of the SolarERAnet project. In addition, material and cell stability, the topic of the StableNextSol action, will be addressed.
The meeting will consist of a poster central session, as well as lectures.
All participants are invited to submit poster abstracts.
