organic-inorganic hybrid tandem multijuntion photovoltaics having an improved lifetime and preparing method for thereof

摘要

The present invention relates to an organic / inorganic hybrid tandem solar cell with improved lifetime and a manufacturing method thereof, and more particularly, to an inverter-type organic / inorganic hybrid tandem solar cell having a rear electrode layer containing silver and a method of manufacturing the same. The present invention relates to a substrate; A transparent electrode layer formed on the substrate; An inorganic photoactive layer in which an n-type amorphous silicon layer / an i-type amorphous silicon layer / a p-type amorphous silicon layer are sequentially laminated on the transparent electrode layer; A hole transport layer laminated on the inorganic photoactive layer; An electron transport layer laminated on the hole transport layer; An organic photoactive layer laminated on the electron transport layer; And a rear electrode layer including silver (Ag) stacked on the organic photoactive layer, and a method of manufacturing the same. The organic / inorganic hybrid tandem solar cell according to the present invention has an inverter type in which a rear electrode layer containing silver is introduced, and has an organic solar cell and an inorganic solar cell including an organic photoactive layer, An inorganic solar cell including a photoactive layer is connected in series to improve efficiency, and power conversion efficiency is maintained over time, which is advantageous for long-term stability.
