Researchers(研究人员) at(at) the Institute(研究所) for(for) Integrated(综合) Cell(细胞)-()Material(材料) Sciences(科学) at(at) Kyoto(京都) University(大学) have(have) made(使) a(一种) popular(流行) type(类型) of(of) dye(染料)-()sensitized(敏化) solar cell(太阳能电池) more(更加) efficient(高效) by(通过) adjusting(调整) and() updating(更新) its() structure(结构).(.) Published(发表) in(in) the Journal(期刊) of(of) the American Chemical Society(美国化学学会) (JACS),((JACS),) the team(团队) report(报告) a(a) series(一系列) of(of) adaptations(适应性) with(with) a(a) power(功率) conversion efficiency(转换效率) of(of) 10.7(10.7) percent(),(,) the highest(最高) yet(然而) for(for) this kind(这种) of(of) dye(染料)-()sensitized(敏化) solar cell(太阳能电池),(,) the most(most) efficient(高效) solar technology(太阳能技术) available(可用) at(at) present(目前).(.)
Current(目前) dye(染料)-()sensitized(敏化) solar cells(太阳能电池) are(are) made(made) up(up) of(of) a(a) porous(多孔) layer() of(of) titanium dioxide(二氧化钛) covered(覆盖) with(with) a(a) molecular(分子) dye(染料).(.) As(As) sunlight(太阳光) is() taken(采取) in,(in,) electrons(电子) are() excited(激发) as(as) they(它们) pass(通过) through(through),(,) and() are() collected(收集) for(for) power(电力) before(before) being() "(")recycled(再循环),"(,") reintroduced(引入) into(into) the electrolyte(电解质) and() back() to(to) the dye(染料) molecule(分子).(.) As(As) they(它们) are(are) lightweight(重量轻) and() low() density(密度),(,) they(它们) have(具有) a(a) high(很高) industry(行业) appeal(吸引力) as(as) a(a) replacement(替代) material(材料) for(for) current(当前) rooftop(屋顶) solar panels(电池板).(.)
There() are() different(不同) approaches(方法) to(to) structuring(构建) these(这些) solar cells(太阳能电池);(;) with(with) aromatic(芳香) ring() fusion(融合) to(to) a(a) porphyrin(卟啉) core(核心) being(being) the most() attractive(有吸引力),(,) as(因为) they(它们) absorb(吸收) red(红光) light() well(很好地).(.) Yet(然而) they(它们) have() their(它们) downsides(缺点):(:) the electrons(电子) are() only(只能) excited(激发) for(for) a(a) short() lifetime(寿命),(,) have() a(a) tendency(倾向) to(to) aggregate(聚合),(,) making(making) conversion(转换) to(to) power(动力) difficult(难以).(.)
In order to(为了) improve(提高) efficiency(效率),(,) Hiroshi(Hiroshi) Imahori(Imahori),(,) Tomohiro(Tomohiro) Higashino(Higashino) and() colleagues(同事) investigated(研究) the use(使用) of(of) a(a) methylene(亚甲基) bridged(桥接) material(材料),(,) fused(融合) to(to) the porphyrin(卟啉) core(核心).(.) They(他们) believed(认为) this() would() overcome(克服) the downsides(缺点),(,) particularly(特别是) by(通过) suppressing(抑制) the aggregation(聚集) and() enhancing(增强) energy conversion(能量转换).(.)
With(With) the new(新型) molecular(分子) dye(染料),(,) DfZnP-iPr,(DfZnP-iPr,) they(它们) achieved(实现了) a(a) higher(更高) efficiency(效率) than(than) previously(先前) reported(报道).(.) They(他们) believe(相信) their(他们) research(研究) will() reinvigorate(重振) the exploration(探索) of(of) aromatic(芳香族)-()fused() porphyrin(卟啉) sensitizers(敏化剂) for(for) these(这些) high() performance(性能) solar cells(太阳能电池).(.)
"(")Growing(越来越) concern(关注) over(over) the use(使用) of(of) fossil fuels(化石燃料) and() environmental(环境) issues(问题) means(意味着) we(我们) need(需要) to(to) work(工作) hard(努力) on(on) improving(改善) sustainable(可持续) energy systems(能源系统).(.) Our(我们) work(工作) improves(提高了) the efficiency(效率) of(of) a(a) lightweight(轻质) and() attractive(有吸引力) solar technology(太阳能技术) and() we(我们) hope(希望) will(will) stimulate(刺激) the research(研究) community() to(to) further(进一步) explore(研究) the potential(潜力) of(of) aromatic(芳香族)-()fused() porphyrin(卟啉) sensitizers(敏化剂) for(for) high() performance(性能) dye(染料)-()sensitized(敏化) solar cells(太阳能电池),"(,") says() Hiroshi(Hiroshi) Imahori(Imahori) of(of) Kyoto(京都) University(大学)'s('s) Institute() for(for) Integrated(综合) Cell(电池)-()Material(材料) Sciences(科学) (iCeMS)((iCeMS))
