A method for manufacturing a perovskite solar cell, includes disposing an electron transport layer on a transparent conductive substrate, disposing an additive-doped perovskite light absorption layer on the electron transport layer, disposing a hole transport layer on the additive-doped perovskite light absorption layer, and disposing an electrode on the hole transport layer. The disposing of the additive-doped perovskite light absorption layer includes adding an additive having hydrophobicity to a perovskite precursor solution, and applying the additive-added perovskite precursor solution onto the electron transport layer to form the additive-doped perovskite light absorption layer.

Perovskite solar cell and method for manufacturing same

Provided is a method comprising acquiring information on a branch formed on blockchain data, calculating a difference in a block height between a target block corresponding to a current block height of the blockchain data and a block in a non-branched state based on the information on the branch and calculating a transaction confirmation reliability of transaction data recorded in the target block based on the difference in the block height, wherein the transaction confirmation reliability indicates a probability that, for as k blocks are further connected after the target block, a position of the block at which the transaction data is recorded will not change, wherein k is an integer greater than zero.

Method for calculating confirmation reliability for blockchain based transaction and blockchain network monitoring system for performing the method

The present invention relates to a method which can effectively remove perovskite light absorbers, hole transport layers, metal electrodes, and the like by immersing a waste perovskite-based photoelectric conversion element module in a cleaning solution under predetermined conditions. The present invention can recover a substrate from the waste module and manufacture a photoelectric conversion element having a photoelectric conversion efficiency level comparable to the initially high level again, using the same.

Method for recycling perovskite-based photoelectric conversion element
