PI: Shengbai Zhang / Hao ZengProposal Number: 1510948 / 1510121The sun represents the most abundant potential source of sustainable energy on earth. Solar cells for producing electricity require materials that absorb the sun's energy and convert its photons to electrons, a process called photovoltaics. Recently, materials based on inorganic-organic halide perovskite materials have achieved promising solar energy power conversion efficiency, and can be made from earth-abundant elements using low-cost, solution based processing methods. However, these perovskite materials contain lead, which is toxic, and degrade in the presence of moisture, which prevents their commercial use. To address these limitations, this project will develop and study the performance of a new class of perovskite materials which do not contain lead and are stable in moisture. This project will also provide educational and outreach opportunities, including the development of a student-designed nanotechnology display as part of the permanent Physics and Art exhibit at Rensselaer Polytechnic Institute, as well as development of various hands-on solar cell kits for K-12 students in the Buffalo area public schools.Photovoltaic (PV) materials based on inorganic-organic halide perovskites have achieved power conversion efficiencies of nearly 18%, which are now comparable to CIGS and CdTe thing film solar PV materials. However, current inorganic-organic halide perovskite materials contain lead and are unstable in moisture. The overall goal of this research is to design and synthesize new ionic photovoltaic absorber materials based on non-halide perovskites that eliminate the use of lead and are stable in moisture. The proposed research has two objectives. The first objective is to understand the physics and chemistry of organic-inorganic halide perovskite materials that determine their power conversion efficiency and photo-induced degradation in water. Based on the fundamental understanding obtained under the first objective, the second objective is to design, synthesize, and characterize the photophysics of new ionic PV absorbers based on the non-halide chalcogenide perovskites which do not contain lead, as well as molecularly doped CuxS compounds proposed by a materials-by-design approach.

PI：Shengbai Zhang / Hao Zengpropossal编号：1510948 /1510121 The Sun是地球上可持续能源最丰富的潜在潜在来源。 用于产生电力的太阳能电池需要吸收太阳能量并将其光子转换为电子的材料，这一过程称为光伏。 最近，基于无机有机卤化物钙钛矿材料的材料已经达到了有希望的太阳能能力转化效率，并且可以使用基于低成本的，基于溶液的加工方法从地球丰富的元素中制成。 但是，这些钙钛矿材料含有有毒的铅，并在水分存在下降解，从而阻止了它们的商业用途。 为了解决这些限制，该项目将开发和研究不含铅且水分稳定的新型钙钛矿材料的性能。 该项目还将提供教育和外展机会，包括开发学生设计的纳米技术展示，作为Rensselaer Polytechnic Institute的永久物理和艺术展览的一部分，以及开发K-12布法罗地区公立学校的学生。基于无机有机卤化物钙钛矿的Photovoltaic（PV）材料已经达到了近18％的功率转换效率，现在可以与CIGS和CDTE Thing Thing Film Film Film胶片太阳能PV材料相提并论。 但是，当前的无机有机卤化物钙钛矿材料含有铅，水分不稳定。 这项研究的总体目的是设计和合成基于非卤化物钙钛矿的新离子光伏吸收材料，这些材料消除了铅的使用并在水分中稳定。 拟议的研究有两个目标。第一个目的是了解有机无机卤化物钙钛矿材料的物理和化学，这些材料决定了其功率转化效率和光引起的水中降解。 基于第一个目标下获得的基本理解，第二个目标是设计，合成和表征新离子PV吸收剂的光体物理学，基于非甲基甲藻素化剂钙钛矿，不含铅，以及分子掺杂的Cuxs Cuxs化合物化合物化合物通过设计材料提出的方法。
