Tailoring perovskite crystallization and interfacial passivation in efficient, fully textured perovskite silicon tandem solar cells

Joule, Journal Year: 2024, Volume and Issue: 8(10), P. 2811 - 2833

Published: July 19, 2024

Fully textured perovskite silicon tandem solar cells are promising for future low-cost photovoltaic deployment. However, the fill factor and open-circuit voltage of these devices currently limited by high density defects at grain boundaries interfaces with charge transport layers. To address this, we devise a strategy to simultaneously enhance crystallization passivate perovskite/C60 interface. By incorporating urea (CO(NH2)2) as an additive in solution step hybrid evaporation/spin-coating deposition method, kinetics accelerated, leading formation desired photoactive phase room temperature. With that, films large sizes (>1 μm) improved optoelectronic quality formed low annealing temperatures (100°C). Concurrently, remnant molecules expelled surface, which locally displaces C60 layer, thus reducing interfacial non-radiative recombination losses. this strategy, resulting achieve 30.0% power conversion efficiency.

Complex Metal Oxides as Emerging Inorganic Hole‐Transporting Materials for Perovskite Solar Cells

Small, Journal Year: 2024, Volume and Issue: 20(25)

Published: Jan. 9, 2024

Abstract Perovskite solar cells (PSCs) have achieved revolutionary progress during the past decades with a rapidly boosting rate in power conversion efficiencies from 3.8% to 26.1%. However, high‐efficiency PSCs organic hole‐transporting materials (HTMs) suffer inferior long‐term stability and high costs. The replacement of HTMs inorganic counterparts such as metal oxides can solve above‐mentioned problems realize highly robust cost‐effective PSCs. Nevertheless, widely used simple oxide‐based are limited by low conductivity poor light transmittance due fixed atomic environment. As an emerging family HTMs, complex superior structural/compositional flexibility attracted increasing interest recently, showing carrier conductivity/mobility superb transmittance. Herein, recent advancements design development for high‐performance summarized emphasizing superiority over counterparts. Consequently, several distinct strategies proposed. Last, future directions remaining challenges also presented. This review aims provide valuable guidelines further robust, high‐efficiency, low‐cost
