US Patent:

20150318477, Nov 5, 2015

Filed:

Jul 10, 2015

Appl. No.:

14/796468

Inventors:

Michael D. Irwin - Dallas TX, US
Jerred A. Chute - Dallas TX, US
Vivek V. Dhas - Dallas TX, US

International Classification:

H01L 51/00
H01L 51/42
C23C 14/06
C07F 7/24
C23C 16/50

Abstract:

A method for processing a perovskite photoactive layer. The method comprises depositing a lead salt precursor onto a substrate to form a lead salt thin film, depositing a second salt precursor onto the lead salt thin film, annealing the substrate to form a perovskite material.

Appl. No.:

14/209013

Inventors:

Michael D. Irwin - Dallas TX, US
Jerred A. Chute - Dallas TX, US
Vivek V. Dhas - Dallas TX, US

International Classification:

H01L 31/032

US Classification:

136260, 136265, 136261, 136262, 136263

Abstract:

Photovoltaic devices such as solar cells, hybrid solar cell-batteries, and other such devices may include an active layer having perovskite material and copper-oxide or other metal-oxide charge transport material. Such charge transport material may be disposed adjacent to the perovskite material such that the two are adjacent and/or in contact. Inclusion of both materials in 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: one or more interfacial layers, one or more mesoporous layers, and one or more dyes.

International Classification:

H01G 9/20
H01L 51/42
H01L 31/032

US Classification:

136261, 136265, 136263, 136264

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.

Appl. No.:

14/281196

Inventors:

Michael D. Irwin - Dallas TX, US
Jerred A. Chute - Dallas TX, US
Vivek V. Dhas - Dallas TX, US

International Classification:

H01G 9/20
H01L 51/00

US Classification:

136263

Abstract:

A photovoltaic cell of improved construction may include an active layer comprising first and second active material, and a dye. Either of the first and second active material may include a copper-oxide compound. The active layer may further include a thin-coat interfacial layer, which may coat at least a portion of either of the first and second active material. The dye may include a primary electron donor moiety, a core moiety, and an electron-withdrawing moiety.
