摘要： The present disclosure provides a panel structure for receiving light and generating electricity. The panel structure comprises a panel material that has a light receiving surface. The panel material is at least partially transmissive for light having a wavelength in the visible wavelength range. The panel structure further comprises a photovoltaic material being positioned in or at the panel material. The photovoltaic material is distributed between transmissive areas that are void of the photovoltaic material such that features of the photovoltaic material are sufficiently narrow to be at least largely invisible to the naked eye.

摘要： A microstructured ZnO coating that improves the performance of Cu(In,Ga)Se2 (CIGS) photovoltaic (PV) devices via two mechanisms; it acts an antireflective layer with superior non-normal performance to thin film anti-reflective (AR) coatings, and it scatters a large fraction of incoming light at a large angle, resulting in absorption that is on average closer to the p-n junction.
