Helm­holtz-Zen­trum Ber­lin für Mater­i­alien und Ener­gie (HZB)

Helm­holtz-Zen­trum Ber­lin für Mater­i­alien und Ener­gie (HZB) invest­ig­ates and devel­ops mater­i­als for a sus­tain­able energy sup­ply. For this pur­pose, we oper­ate the syn­chro­tron facil­ity BESSY II as well as sev­eral core labs, which offer an enorm­ous vari­ety of ana­lyt­ical meth­ods for invest­ig­at­ing mater­i­als. The unique research envir­on­ment at BESSY II is also attract­ive for external users from all over the world. With approx. 1,200 employ­ees, the HZB is today one of the largest non-uni­versity research centres in Ber­lin. More inform­a­tion:

SCI­ENCE + CAREER + DIVERSITY = HZB

... is the for­mula for our suc­cess­ful human resources policy. We offer wide-ran­ging internal and external qual­i­fic­a­tion oppor­tun­it­ies for our employ­ees, includ­ing spe­cial sup­port for junior sci­ent­ists. Our fam­ily-friendly work­place policy includes flex­ible work­ing hours and tele­work arrange­ments. HZB val­ues diversity as driver for suc­cess­ful sci­entific col­lab­or­at­ive work and pro­motes a sup­port­ive work­ing atmo­sphere for people from all back­grounds.

PhD Stu­dent (f/m/d) Per­ovskite/Sil­icon tan­dem solar cells – char­ac­ter­iz­a­tion and mod­el­ing for highest per­form­ance and energy yield

English

Ref­er­ence No.: EE 2020/41

Work­ing field:

The young invest­ig­ator group "Per­ovskite Tan­dem Solar Cells" has recently pub­lished two record effi­cien­cies for per­ovskite/CIGS as well as per­ovskite/sil­icon tan­dem solar cells. The aim of the group is to fur­ther optim­ize this fas­cin­at­ing tan­dem tech­no­logy by detailed under­stand­ing of the dom­in­ant loss mech­an­isms. With this announced PhD pos­i­tion, detailed optical and elec­trical char­ac­ter­iz­a­tion should help to improve the per­form­ance and energy yield of per­ovskite-based tan­dem solar cells.

The announced PhD pos­i­tion is embed­ded in the broad HZB infra­struc­ture, includ­ing the Helm­holtz Innov­a­tion Lab HyS­PRINT. Col­lab­or­a­tion is planned with the Com­pet­ence Centre Photo­vol­ta­ics Ber­lin (PVcomB), espe­cially with the group for Out­door Per­form­ance Ana­lysis at HZB and the 'Labor­at­ory of photo­vol­ta­ics and opto­elec­tron­ics' at the Uni­versity of Ljubljana in Slov­e­nia. This col­lab­or­a­tion offers the oppor­tun­ity to bridge the gap between fun­da­mental research and indus­trial applic­a­tions.

Topic of the doc­toral thesis: Per­ovskite/Sil­icon tan­dem solar cells – char­ac­ter­iz­a­tion and mod­el­ing for highest per­form­ance and energy yield.

The PhD stu­dent will be a mem­ber of the Gradu­ate School "Hybrid Per­ovskites Solar Cells" (HyPer­Cells).
