Abstract

According to the embodiments of the present invention, a gel is provided. The gel has a composition including clay nanoparticles and a halide perovskite material of the general formula AMX3, where A may be an organic or inorganic ion, M may be a metal cation or element, and X may be a halogen anion or element, such as methylammonium lead iodide (CH3NH3Pbl2). According to further embodiments of thepresent invention, a method of forming a gel, a photovoltaic device and a method of forming a photovoltaic device are also provided.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to Singapore Patent Application No. 10201500940Q filed 6 February 2015, the contents of which are hereby incorporated by reference in their entirety for all purposes. technical field [0003] Various embodiments relate to a gel, a method of forming a gel, a photovoltaic device, and a method of forming a photovoltaic device. Background technique [0004] Inorganic-organic lead halide perovskites have gained great attention as photovoltaic device materials due to their favorable electrical and optical properties as well as their solution processability. A high power conversion efficiency (η) above 17% was reported, which is equivalent to that of commercial solar cells made of silicon, copper indium gallium selenide (CIGS), or cadmium telluride (CdTe). [0005] Typically, the perovskite structure consists of corner-corner connected MX 6 A three-dimensional network composi...
