“…The device also exhibited decent stability, with only a 14% performance loss after 500 h at room temperature operation. In another study, Cao et al deposited a CZTS layer in-between carbon HTL and perovskite as a second HTL [87]. Devices with double CZTS/carbon HTL showed almost 50% better performances, reaching around 12.5% efficiency.…”

Kesterite Cu2ZnSnS4 (CZTS) has attracted attention as an earth-abundant alternative to commercially successful CIGS solar cells. CZTS exhibits decent optoelectrical properties while having excellent stability on top of being an earth-abundant, low-cost and non-toxic material. Therefore, in recent years, there has been a significant research effort to develop CZTS-based devices. The efficiency of CZTS solar cells reached 12.6% in 2013, and this was a remarkable achievement at the time. However, the efficiency of these devices has been stagnant since then while emerging technologies, most notably perovskite solar cells, keep breaking record after record. Currently, CZTS research focuses on discovering the secrets of material properties that hinder the efficiency of CZTS solar cells while branching out to develop alternative applications for this material. In this review, we summarize the interesting properties of CZTS as well as its promising applications, which include thin-film solar cells, charge-transfer layers in perovskite solar cells, and photoelectrochemical water splitting while briefly commenting on its other possible applications.

“…In a separate vial, 224 mg of sulfur powder is dissolved in 7 mL of oleylamine, quickly injected into the previous oleylamine solution at 230 °C, and allowed to react for 30 min. The obtained Cu 2 SnS 3 nanocrystals are carefully washed four times following our previous procedure and dried at 70 °C. − …”

Integrating a suitable hole-transport layer into carbon electrode-based perovskite solar cells can effectively promote their power conversion efficiencies. Here, Cu2SnS3 nanocrystals are synthesized by the hot-injection method, and their potential to function as hole-transport layers in carbon electrode-based perovskite solar cells is evaluated for the first time. The Cu2SnS3 nanocrystal hole-transport layer can efficiently extract photogenerated holes from perovskite films and suppress charge carrier recombination. As a result, carbon electrode-based perovskite solar cells employing Cu2SnS3 hole-transport layers can demonstrate a maximum power conversion efficiency of 16.75%.

“…[ 219 ] Recently, NiCo 2 O 4 has also shown good performance as HTL, and the hysteresis is obviously suppressed. [ 220 ] Some inorganic materials containing copper have also been used as HTL, such as CuSCN, [ 221 ] CuI, [ 221 ] CuS, [ 56 ] Cu 2 ZnSnS 4 , [ 222 ] copper phthalocyanine (CuPc), [ 223 ] and CuO x . [ 224 ] For example, CuSCN as HTL has a high hole mobility and suitable energy level, which can promote carrier transport at the interface.…”

The power conversion efficiency (PCE) of perovskite solar cells (PSCs) has exceeded 25%, showing great potential in the photovoltaic field. However, PSCs often show anomalous current density–voltage (J–V) hysteresis behavior in the forward and reverse scanning directions, which makes it impossible to accurately evaluate the performance of PSCs. Therefore, it is necessary to clearly understand the mechanism of hysteresis and suppress the hysteresis. Herein, the J–V hysteresis behavior in PSCs and strategies to suppress hysteresis is focused: first, the various factors that affect J–V hysteresis in PSCs are summarized. And the mechanism behind the various possible origins of hysteresis and the challenges encountered are explored. Then, the strategies to suppress or eliminate the hysteresis are summarized, including optimizing the perovskite light‐absorbing layer, improving the performance of the carrier transport layer and interface engineering. Finally, insights on the future development of the hysteresis are also provided.
