https://diode.zone/videos/watch/7679dd9c-d6ee-4f4b-80fe-c97a2a3838ed There are two main challenges in modern photovoltaics: (i) improving the efficiency of existing solar cells; (ii) searching new approaches, materials and technologies to reduce the cost of converting solar energy into electricity. Here we report the possibility to solve both problems by forming a silicon-heterocyclic amine hybrid due to deposition of organic layers from chemical solutions at room temperature onto Si patterned substrates [1, 2]. Aqueous organic and mixed solvents of thiamine diphosphate hydrochloride (TD), procainamide hydrochloride (PRO), clonidine hydrochloride (CLON), cyanocobolamine (CYCAM), metamizole sodium (MS), laevomycetin (LM) were used for chemical film deposition at room temperature under ambient laboratory conditions. The PV performance as function of the PD molecular structure, hybrid morphology, deposition regime and power solar energy has been analyzed using SEM, optical microscopy, XRA, FTIR spectroscopy, spectral photoresponse study and PV diagnostics. The hybrids have demonstrated the solar energy conversation with an efficiency of 3.7 % to 8.4 % depending on the used organics, chemical solutions and surface and/or interface morphology. Such hybrid organic-inorganic architecture designs with PD yields a number of advantages: (i) the absence of high-temperature thermal treatment and high vacuum; (ii) the lack of purification and additional doping; (iii) better use of the solar spectrum due to Si substrates; (iv) use of an inexpensive and non-aggressive organic medium. Some approaches are being developed to increase efficiency, for example, through the use of plasmonic Au nanoparticles [3] or an additional layer of organic dye [4]. Research is in progress.
