From the lab to roof top applications: outdoor performance, temperature behavior and energy yield of perovskite solar cells

We perform rooftop testing of 6 perovskite solar cells. The devices are tracked under maximum power point and weather data is collected over several weeks. In addition, the changing irradiance and temperature conditions are also investigated under controlled laboratory conditions, where maximum power temperature coefficient of -0.17%/K is extracted. With the help of optical simulations and measured weather data, we are able to model the generated power of our devices. The temperature dependent energy yield can therefore be used to predict energy output or monitor the degradation of devices.
