A hybrid organic -inorganic solar cell is provided that includes a substrate, a
transparent conductive oxide (TCO) layer deposited on the substrate, an n-type electron transport material (ETM) layer, a p-type hole transport material (HTM) layer, an i-type perovskite layer, and an electrode layer, where the substrate layers are arranged in an n-i-p stack, or a p-i-n stack, where the passivating
barrier layer is disposed between the layers of the (i) perovskite and HTM, (ii)
perovskite and ETM, (iii) perovskite and HTM, and perovskite and ETM, or (iv)
TCO and ETM, and ETM and perovskite, and perovskite and HTM, or (v) substrate
and TCO, and TCO and ETM, and ETM and perovskite,and perovskite layer and
HTM, or (vi) a pair of ETM layers, or (vii) a pair of HTM layers.
