“…Organic–inorganic hybrid lead halide perovskite solar cells (PSCs) have experienced dramatic development in both power conversion efficiencies (PCEs) and long-term stability, showing great prospects for practical application in future photovoltaic fields. − Nevertheless, lead toxicity poses a great hurdle toward PSCs’ commercialization . Efforts are growing to alleviate the lead problem by seeking alternative, lead-free halide perovskites, among which Sn-based halide perovskites are superior to all lead-free perovskites reported so far in terms of photovoltaic performance. , In this sense, considerable efforts are being made in developing highly efficient and stable Sn-based PSCs; however, there still exists a distinct gap in comparison with the lead counterparts because of the severe open-circuit voltage loss ( V oc deficit, which is defined as E g / q – V oc ) and instability issues. , …”

Open-circuit voltage loss and instability from surface Sn(II) oxidation and high-density Sn vacancies pose great hurdles for developing highperformance Sn-based perovskite solar cells (PSCs). Turning attention from the bulk microstructure to surface reconstruction is promising to push the performance enhancement of Sn-based PSCs. Herein, a surface-modulation strategy based on 6-maleimidohexanehydrazide trifluoroacetate is rationally designed to reconstruct the surface structure of FASnI 3 films to manage the Fermi level and passivate defects. The electronic state evolution results in an n-type Fermi level shift of the shallow surface, thereby forming an extra back-surface field for electron extraction. Meanwhile, the ion-pairing agent affords passivating cationic and anionic defects, thereby nullifying the charged-defect-rich surface. In particular, the reductive hydrazide group and carboxyl groups alleviate superficial Sn(IV) and inhibit Sn(IV) formation, homogenizing surface potential and prolonging carrier lifetime. Accordingly, devices deliver a champion power conversion efficiency (PCE) of 13.64% and an elongated lifespan, with over 75% of the original PCE after 1000 h of illumination (O 2 < 50 ppm). This work presents a new insight on the surface reconstruction strategy for developing high-performance Sn-based PSCs.

“…The analysis below will focus on PSCs as they have achieved the highest efficiencies, 47 are generally seen as the most disruptive 53,54 and are closest to commercialization out of the emerging photovoltaic materials. 55 However, several other emerging photovoltaic technologies, such as organic, kesterite and quantum dot solar cells, offer similar advantages in ease of processing, and the analysis below is also largely valid for these technologies. Successful deployment of PSCs could function as a blueprint for the roll-out of other emerging photovoltaic technologies.…”

“…PSCs are an excellent solution for powering consumer electronics, especially Internet of Things (IoT) ecosystems, where billions of sensor nodes are connected to the grid. , Current research trends move toward low-power equipment and protocols, improving energy utility to increase network coverage, reduce latency, minimize energy loss, and improve data reliability. The IoT market has been growing exponentially, creating a massive web of interconnected devices, including smartphones, kitchen appliances, industrial robots, healthcare devices, or connected cars.…”
