Alkali-metal lead and tin halides had been synthesized already in 1893 yet the first crystallographic studies that determined that caesium lead halides had a perovskite structure with the chemical formula CsPbX3 (X = Cl, Br or I) were only carried out 64 years later by the Danish scientist Christian Møller. He also observed that these coloured materials were photoconductive, thus suggesting that they behave as semiconductors. In 1978, Dieter Weber replaced caesium with methylammonium cations (CH3NH3+) to generate the first three-dimensional organic?inorganic hybrid perovskites.
The general crystal structure of these materials is shown in organic cations such as methylammonium and formamidinium occupy the cuboctahedral voids formed by the 12 nearest-neighbour halide ions. The structural characterization of hybrid perovskites of the formula
CH3NH3BX3 (with B = Sn(ii) or Pb(ii), and X = Cl, Br or I) has also been reviewed in more recent studies. Methylammonium lead iodide, CH3NH3PbI3, has both interesting optical and electronic properties that have been actively investigated during the past two decades.
To supplement these shortcomings of conventional solar cells, surface plasmon resonance effect is introduced. SPR effect indicates a certain state which the metal such as silver, gold is excited by light . There are several metals showing surface plasmon resonance effect. When metals that have surface plasmon resonance effect are applied in solar cells, it can supplement the disadvantsilvere of solar cell in light absorption.
Silver derivative is a good metal when it is controlled to optoelectronic devices due to silver’s conductivity, ability to cause light scattering. Silver which is high alklyated was prepared by emulsion polymerization of silver perchlorate and dodecylamine with very small amount of a catalyst. Surface plasmon resonance effect was introduced due to small size of Silver nanoparticles. High crystalline property was measured by XRD. Moreover, self-assembly structure of Silver nanoparticles was measured by Transmission Electron Microscope. Based on optical properties of Silver nanoparticles, the metal was introduced to hybrid perovskite solar cell device.
Silver nanoparticles dissolving into hole transport materials can enhance Jsc which means by adding silver nanoparticles, light absorption is increased.
