Can a unified testing protocol improve the performance of flexible solar panels?

In a recent article in the journal Nature Energy, a committee of 23 PV and mechanical performance experts of 12 nationalities have introduced a unified testing protocol aimed at improving consistency in the evaluation of flexible solar cells and panels.

What is the bending test protocol for flexible photovoltaics?

Recently, Fukuda et al. proposed a bending test protocol for the mechanical characterization of flexible photovoltaics, recommending 1% strain over 1 000 bending cycles, along with a comprehensible discussion of best practices for mechanical bending methodology and measurement conditions.

Can bending test be standardized for flexible solar cells?

Recently, Fukuda et al. (2024) propose a bending test protocol for standardizing the mechanical performance characterization of flexible solar cells, focusing on 1% strain over 1 000 bending cycles. This marked an important step toward establishing consistency and good practices in the literature.

What is flexible photovoltaic research?

Notably, current flexible photovoltaic research predominantly focuses on the retention of PCE following mechanical testing, often over hundreds or thousands of bending cycles with different bending radii. Parameters such as bending radius (R) and number of bending cycles (NBC) are frequently reported.

Can solar cells be mechanically flexible?

However, even with this unified protocol, accurately comparing the mechanical flexibility of solar cells is hindered by the variated influence of parameters like thickness, bending radius, and power conversion efficiency (PCE) evolution during mechanical testing.

What are flexible photovoltaic devices?

Nature Energy 9, 1335–1343 (2024) Cite this article Flexible photovoltaic (PV) devices are a promising research field with potential for wearable, portable, indoor and internet-of-things applications. Substantial progress has been made in recent years, with flexible emerging PVs reporting power conversion efficiencies (PCEs) of over 24%.
