Dry-processing of metal halide perovskites into thin films

Introduction

Perovskite semiconductors are promising for photovoltaics with a potentially very large market. Industrial compatible deposition processes that do not employ solvents are currently unavailable.

New Deposition Process

We have developed a new deposition process that is completely solvent-free, compatible with a wide range of perovskite precursors, operates at moderate vacuum levels, and leads to high-quality films with crystal grains in the order of 500 nm.

Project Goals

In the APERITIF project, we aim to attract industrial sponsors, including:

1. Equipment manufacturers
2. Photovoltaic module producers

Our goal is to license this novel process and use it to build a larger scale prototype and implement it for larger area solar cells.

Intellectual Property Protection

To protect this process and the novel perovskite compositions and subsequent solar cells, we will file patents.

Expected Outcomes

In view of the superior perovskite film quality, we expect to obtain more efficient and stable photovoltaic devices.

Production Advantages

As the processing method is compatible with continuous operation, it allows for high-speed production, which is urgently needed to address the enormous growth scenarios of photovoltaic panels.
