Organic-inorganic hybrid lead halogenide perovskites have attracted vast attention ever since it was first applied to solar cells as light absorber in 2009. Efficiency as high as 25.5% was obtained for small area lab cells after a decade’s efforts made by researchers all over the world. However, prior to the mass production of this type of photovoltaic devices, some key issues, such as large area deposition, monolithically interconnected module fabrication and stability improvement, have to be solved. In this talk, we will present our recent progress in the efficiency enhancement in all-inorganic and hybrid perovskite solar cells and modules. Aperture area efficiencies of 21.37% and 19.21%, certified an independent third party, were achieved for inverted perovskite mini-modules on glass and flexible polymer substrates, respectively. In addition, mini-module with efficiency over 30% measured under LED indoor light illumination was obtained for indoor light harvesting application, either.
