Photoexcitation of coordinated complex 1 leads to the formation of charge-transfer complex Cu2+(DDQ•−)2 (2). The charge transfer complex 2, when spun on solid substrates, forms nanowires. Sandwich structures of 2 exhibit electrical bistability associated with memory phenomenon. Read-only and random-access memory phenomena are evidenced in nanowires of 2 providing a route to attend the issues pertaining to the addressibility of organic memory devices.</p>1 aRath, Arup, Kumar1 aDhara, Koushik1 aBanerjee, Pradyot1 aPal, Amlan, J.  uhttps://library.ncl.res.in/content/nanowires-metal-organic-complex-photocrystallization-system-achieve-addressable-electrically01259nas a2200157   4500008004100000245012600041210006900167260000800236300002300244490000700267520063700274100001900911700002200930700001900952856013000971       2010                        eng d00aNear-IR activity of hybrid solar cells: enhancement of efficiency by dissociating excitons generated in PbS nanoparticles0 aNearIR activity of hybrid solar cells enhancement of efficiency   cFEB  aArticle no: 0735050 v963 a<p>Photovoltaic devices based on PbSnanoparticles remained inactive in the near-IR region due to a not-so-favorable energy band-diagram that does not allow dissociation of excitons generated in PbS. In this work, with the introduction of nanostructures in the PbS-based hybrid system, we show an enhancement of photovoltaic performance in both visible and near-IR regions. The addition of increases the power conversion efficiency from 0.006% to 0.12%. With the aid of energy band-diagram, we show that excitons generated in PbS even in the near-IR range can now become dissociated to yield photocurrent in the external circuit.</p>1 aGuchhait, Asim1 aRath, Arup, Kumar1 aPal, Amlan, J.  uhttps://library.ncl.res.in/content/near-ir-activity-hybrid-solar-cells-enhancement-efficiency-dissociating-excitons-generated
