**Welcome to HZB Optics for Solar Energy** 👋

We work on next generation experimental, numerical and ML-based optics in and for photovoltaic devices. 

From an optical point of few the sun ☀️ is a challenging energy source: solar energy devices 🔌 have to be optimized for a broad spectral range and for a light source 💡 changing the illumination direction during the course of the day and the year 🌍 with varying shares of direct and diffuse irradiance.

Here you will a number of models that focus on the characterization, monitoring and design of new photovoltaics devices. Check out for example our latest diffusion models for inverse thin film material design.
