The structure of perovskite solar cell
Perovskite solar cells generally includes anode(FTO), N-type electron transfer layer, Perovskite absorption layer, P-type hole transporting layer and cathode(Au)

The structure or perovskite
Perovskites are materials described by the formula ABX3
1. Light extinction coefficiency 10 times higher than Dyes 2. Stability 3. Bandgap controllable
Perovskite can produce electrons and holes, electronic passes through electronic transport layer to the anode and to the cathode through the external circuit. meanwhile, hole can go to the cathode by hole transport layer, and combined with electron to complete a loop here.

The type of perovskite solar cell
Mesoscopic ultra structure perovskite solar cell Structure：similar to Dye-sensitized solar cell Characteristics：a low energy loss and a hபைடு நூலகம்gh photoelectric conversion efficiencies but much interfacial defects has been existed in the solar cell.

The type of perovskite solar cell
Planar perovskite solar cell Structure：don't need a three-dimensional skeleton for supporting materials， mainly consist with conductive glass substitute(FTO), composite oxide layer, perovskite layer, MTL, and metal electrode. Characteristics：simplified the structure of solar cell and the inter defects has been controlled.

The type of perovskite solar cell
Dye-sensitised perovskite type solar cells Structure：similar to Dye-sensitized solar cell，consist with photo-anode， photoabsortion material，HTM，counter electrode. Characteristics：a stable structure and easy to product，but it can't exist without the mesoporous nano oxide layer and much interfacial defects has been existed in the solar cell.
