We demonstrate how perovskite hysteresis can result in permanent reductions in power output in perovskite/silicon tandem modules—including irreversible hotspot-induced damage—from only brief periods of shading.

In this work, we find that the crystallization of ALD TiOx is very sensitive to the film’s thickness, where a small increase in TiOx thickness can trigger a phase change from amorphous TiOx into anatase, which causes a significant increase in J0s. More importantly, we demonstrate that the incorporation of Al ions into the TiOx films inhibits crystallization, which in turn retains excellent passivation for thicker TiOx.

• Optimizing module design for a maximum annual performance. • Detailed gain and loss analysis from cell under STC to module in real environment. • Understanding the impact of module material on the annual module yield. • Impact of angular light, temperatures, lower irradiances on module performance. • Impact of weather condition (ambient temperature, wind speed) on module performance.

Accurate energy yield prediction is of utmost importance for commercial scale photovoltaic systems. One key parameter crucial to the prediction accuracy is the quality of solar radiation data. Most energy yield prediction models rely on Typical Meteorological Year data with maximum temporal resolution of one hour. In this work we develop a methodology to generate Typical Meteorological Year data with much higher time resolution using gap filling methods that aim to maintain high-quality solar radiation data for photovoltaic yield modelling.

The SoERC conference is Australia's first research-only conference that highlights the latest advances in energy research. The conference takes place on 3rd and 4th July at the Australian National University, Canberra.

Impact of perovskite solar cell degradation on the lifetime energy yield and economic viability of perovskite/silicon tandem modules

Hotspots are a major source of failure for photovoltaic modules in the field. The current standard for module testing IEC 61215-2 can leave critical hotspots undetected in half-cut solar cell modules.

A two‐step method to simulate the spatially resolved temperature of a partially shaded cell in a crystalline silicon photovoltaic (PV) module is presented and tested.

We present a passivated contact technology based on polysilicon deposited using low pressure chemical vapour deposition (LPCVD) over an ultra-thin silicon dioxide layer, which achieves an excellent surface passivation with implied open-circuit voltage of 735 mV, a recombination prefactor below 1 fA cm−2 and contact resistivity below 1 mΩcm2.

In this paper, the fabrication of a 22.8% efficient all‐laser‐doped IBC solar cell with localized boron and phosphorus doped contacts is reported.

In this work, we introduce novel test structures and perform numerical simulations to accurately determine the contact properties of 30 μm × 30 μm-sized laser-doped localized contacts.
