Recent development in perovskite solar cell based on planar structures

Abstract

Perovskite materials can revolutionize the solar energy industry due to their unique features and most importantly, the efficiency of perovskite solar cell (PSC) has been enhanced to above 21% (with TiO2mesoporous structure) within few years. There are increasing studies focusing on the area of planar structures (n-i-p and p-i-n) of PSC because of its processibility for large-scale production. Particularly, p-i-n (inverted) structure has attracted attention because it overcomes the drawback of mesoporous and n-i-p (regular) structure of PSCs and reached the power conversation efficiency (PCE) above 20%. In this paper, we present the introduction and classification of photovoltaic (PV) technologies, a brief description of the planar structure of PSCs, and recent improvement in the inverted structure of PSCs.
