Abstract: A method for preparing an inorganic perovskite battery based on a synergistic effect of gradient annealing and antisolvent includes preparing a perovskite layer by a gradient annealing and an antisolvent treatment. A thickness of the perovskite layer is 100 to 1000 nm; when preparing a perovskite precursor solution of the perovskite layer, a solvent is an amide-based solvent and/or a sulfone-based solvent; a concentration of the perovskite precursor solution for preparing the perovskite layer is 0.4 to 2 M; and the gradient annealing is conducted at 40 to 70° C./0.5 to 5 min+70 to 130° C./0.5 to 5 min+130 to 160° C./5 to 20 min+160 to 280° C./0 to 20 min; and a solvent for the anti-solvent treatment is an alcohol solvent, a benzene solvent or an ether solvent.

Abstract: A method for manufacturing a perovskite solar cell, includes disposing an electron transport layer on a transparent conductive substrate, disposing an additive-doped perovskite light absorption layer on the electron transport layer, disposing a hole transport layer on the additive-doped perovskite light absorption layer, and disposing an electrode on the hole transport layer. The disposing of the additive-doped perovskite light absorption layer includes adding an additive having hydrophobicity to a perovskite precursor solution, and applying the additive-added perovskite precursor solution onto the electron transport layer to form the additive-doped perovskite light absorption layer.

Abstract: A photovoltaic device comprises plural layers separated into plural cells, each comprising a region of a photoactive layer and electrodes on opposite sides thereof. Each of the regions of the photoactive layer are formed comprising a first part that comprises photoactive material and a second part that is not photoactive and that has a greater transmittance of visible light than the light absorbing photoactive material, in pre-selected locations, or in a pre-selected distribution of locations, across the region of the photoactive layer. One of the first and second parts are located in plural separate areas within the other of the first and second parts. The transparency of the photovoltaic device is increased by the transmission of light through the second part that is not photoactive.

Abstract: A photoelectric conversion device includes: a photoelectric conversion element; a voltage converter; an electric storage; a load; a voltage monitor; a switch that switches between a first state and a second state; and a controller. In the first state, a voltage output from the voltage converter is applied to the electric storage but not the load, and in the second state, the voltage output is not applied to either the electric storage or the load. When the monitored voltage of the electric storage reaches a full charge voltage of the electric storage, the electric storage is discharged and a voltage is applied to the load by switching the switch to the second state. When the monitored voltage of the electric storage becomes less than the full charge voltage of the electric storage, the electric storage is charged by switching the switch to the first state.

Abstract: Photovoltaic devices such as solar cells, hybrid solar cell-batteries, and other such devices may include an active layer disposed between two electrodes, the active layer having perovskite material and other material such as mesoporous material, interfacial layers, thin-coat interfacial layers, and combinations thereof. The perovskite material may be photoactive. The perovskite material may be disposed between two or more other materials in the photovoltaic device. Inclusion of these materials in various arrangements within an active layer of a photovoltaic device may improve device performance. Other materials may be included to further improve device performance, such as, for example: additional perovskites, and additional interfacial layers.
