   perovskite solar cell


 The organic-inorganic hybrid perovskite solar cell, which is cheap and easy-to-make photo-absorption materials, has highly increased the power conversion efficiency of thin film solar cells in the recent years. We also used the work function controllable conducting polymers as the efficient charge extraction interlayer in perovskite solar cells.

We increased the WF of self-organized HEL(SOHEL)up to the same level of HOMO level of MAPbI3. As a result, the planar perovskite solar cells with SOHEL increased the built-in potential of the device, so it showed the significantly high performance.




Organic/inorganic hybrid perovskite has much higher color-purity and lower cost compared with organic emitters and inorganic QD emitters. Also efficiency of PeLED can be increased by fine stoichiometric tuning that prevents exciton dissociation, and nanograin engineering that reduces perovskite grain size, and concomitantly decreases exciton diffusion length.




















Our study reduces the technical gap between PeLEDsand OLEDs or quantum dot LEDs and is a big step toward the development of efficient next-generation emitters with high color purity and low fabrication cost based on perovskites.
