“…акцепторные материалы В разработке новых ПCЭ в последние годы широко используются бесфуллереновые акцепторы, в том числе ПCЭ с объемной гетероструктурой и послойной структурой [19][20][21]. В отличие от широко используемых фуллерен-содержащих акцепторов (таких как PC 61 BM и PC 71 BM), бесфуллереновые акцепторы легко настраиваются по их оптическим свойствам и по энергии запрещенной зоны.…”

Быстрое развитие технологий полимерных солнечных элементов (ПСЭ) в последние годы позволили достичь впечатляющих успехов в повышении эффективности преобразования энергии (ЭПЭ), достигнув значения последней более 19 процентов, что демонстрирует большие перспективы их практического применения в будущем. Достижения в области новых материалов для указанных целей, в том числе: донорных из сопряженных полимеров, олигомеро-подобных органических молекул, а также полимерных акцепторов на основе фуллеренов и нефуллереновых молекул, однокомпонентных ПСЭ и водно/спирто-растворимых интерфейсных материалов в качестве буферного слоя, стали основой для исследований новых перспективных ПСЭ. Исходя из этого, в настоящей статье проанализированы различные типы материалов, используемых для ПСЭ, их преимущества и недостатки для практического применения в солнечной энергетике.

“…As for other BDT derivatives,TBFT-TR (2020) was reported based on the donor unit TBzF; [447] DT-BDT (2016) , [418] ZR1 (2019) [448] and SM-DTBDT (2021) [372] were prepared by introducing DTBDT as donor unit; BBTSM-1 (2023) and BBTSM-2 (2023) were also synthesized based on the BDT derivative unit BzBT. [449] Comparing the detailed photovoltaic parameters between BBTSM-1: Y6 based and BBTSM-2: Y6 based OSCs, π-bridge unit in BBTSM-1 with a longer alkyl chain octyl significantly optimized the light absorption, molecular stacking and miscibility in the active layer, which explains the reason why BBTSM-1: Y6 based OSC achieved a higher V oc (0.87 V),J sc (20.7 mA/cm 2 ) and FF (62.3%). Furthermore, although the advantage of highV oc in such SMD-based OSC devices has been weakened, the significantly enhanced J sc andFF endows TBFT-TR: Y6 based (14.03%), ZR1: Y6 based (14.27%) and SM-DTBDT: Y8 based (12.45%) OSCs with a higher PCE .…”

In recent decades, the demand for clean and renewable energy has grown increasingly urgent due to the irreversible alteration of the global climate. As a result, efficient organic solar cells (OSCs) have gradually gained attention as a study hotspot. To break up this dilemma, this paper reviews the molecular design strategies of benzodithiophen (BDT)-based polymer and small molecule donor materials since their birth, focusing on the development of main-chain engineering, side-chain engineering and other unique molecular design paths. Up to now, the state-of-the-art power conversion efficiency (PCE) of binary OSCs prepared by BDT-based donor materials has approached 20%. Our work detailly discusses the potential relationship between the molecular changes of donor materials and photoelectric performance in corresponding OSC devices, thereby presenting a rational molecular design guidance for stable and efficient donor materials in future.

“…[14][15][16] In addition, good thermal and photochemical stabilities are also preferred for efficient HTMs. [17][18][19] Up to now, 2,2 0 ,7,7 0 -tetrakis[N,N-di(4-methoxyphenyl)amino]-9, 9 0 -spirobifluorene (Spiro-OMeTAD) featuring a spiro framework and four electron-rich arylamine substituents is still the most commonly used HTM in highly efficient PSCs. [20][21][22] Unfortunately, the complex synthesis and purification process of the spirobifluorene central core make the cost of Spiro-OMeTAD extremely high, which significantly limits its future commercial application.…”
