“…Thus, a correlation between the strength of intermolecular interactions, revealed by single crystal X-ray diffraction studies, with band gap energy of 1-4 can be established. The optical band gaps of diamines 4 and 5 are comparable with the optical band gaps recently reported for triphenylamine flanked thiazole-based small organic molecules [34].…”

“…Moreover, the width of half peak of the (1 0 0) of VC96 is narrower than that of VC97, which indicates that VC96 has better ordered crystalline domains in the blend than VC97 and it is easier for PC 71 BM to admix into the loosely stacked VC97 molecules than VC96. This ease of insertion results in higher miscibility of VC97 and PC 71 BM, which has adverse effects on the purity of the crystalline domains [49][50][51], and thus leads to widening of the half peak of the (1 0 0). In the case of VC96:PC 71 BM blend the well ordered crystalline domains of the VC96 donor promote the escape of charge from the D-A interface, which reduces the bimolecular recombination, a higher utilization rate of absorbed photons and a higher J sc .…”

“…The solar cells based on molecule 3a and PC 71 BM with a 1 : 4 weight ratio reached a PCE of 2.20%, two times higher than that of 3b. Later, the same research group reported two D-A-D type molecules, 5,5-bis (2-triphenylamino-3-decylthiophen-2-yl)-2,2-bithiazole (4a) and 2,5-bis (2-triphenylamino-3-decylthiophen-2-yl)thiazolo [5, 4-d]thiazole (4b) [26]. Compounds 4a and 4b had strong absorptions in the range of 300-560 nm.…”

Organic bulk heterojunction (BHJ) solar cells based on small molecular donors have received great attentions recently, because small molecules possess the merits of high purity, well-defined molecular structures, definite molecular weights and high charge carrier mobility. The highest power conversion efficiency (PCE) of BHJ solar cells based on small molecular donors and fullerene derivative acceptors has reached 7.38%. In this review, we will briefly summarize the development of small molecular donor based BHJ solar cells in the past two years. These results suggest that small molecular donors are promising candidates for high efficiency BHJ solar cells. Due to the environmental constraints and the predicatable exhaustion of fossil energy resources, it is one of the major challenges in the 21st century to find clean and renewable energy. Solar energy which has the potential to act as renewable and clean energy sources is believed one of the promising and long term alternatives to replace fossil energy in the future. Currently, solar cells based on silicon have been practically applied, however, the high cost hinders their wide applications. Comparing with the well-studied silicon solar cells, photovoltaic devices based on organic semiconductors have attracted great attentions recently because they can be fabricated on flexible substrate with large scale at low-cost [1,2]. In this review, we will mainly focus on the development of organic BHJ solar cells. Organic BHJ solar cells consist of electrodes (cathode and anode), donor and acceptor blended active layer and substrate. Based on the donor used into solar cells, they can be briefly divided into two classes, polymer donor solar cells and small molecular donor solar cells. Currently, the polymer donor solar cells have made great progress [3][4][5][6][7], and the highest power conversion efficiency (PCE) reported in literatures has been over 8% [8,9]. In spite of the high performance, there are disadvantages for polymer donors [10], for instance, the high molecular weight dispersity, the batch to batch reproducibility, and so on. On the other hand, small molecular donors do not have the drawbacks mentioned above. In contrast, they have high purity, well-defined molecular structures, definite molecular weights, as well as high charge carrier mobility [11]. As a result, small molecular donors have attracted more and more attentions for photovoltaic applications recently and the highest PCE of BHJ devices based on small molecular donors has reached 7.38% [12].Considering several reviews have summarized the application of small molecular donors in BHJ solar cells [13][14][15][16][17][18][19][20][21], in the present review, we will mainly focus on the development of small molecular donor BHJ solar cells in the past two years. The review will classify the donors based on their device fabrication technique. And the principle of organic solar cells which can be found in the previous reviews
